From an early age we are all well aware of where we are heading - 6 feet under - but little did we know that the 21st century would mix things up a bit. Checking out is cool now. You can be 3D printed into a clothes peg, or have your ashes sent into space so you become actual space dust. The downside is the death part, but we can gloss over that for now and try to get excited, or terrified in some cases, for what is to come for us and our loved ones. Burial alternatives have never really existed before, outside of cremation and a few of the below - keep your eye out for Dissolution and maybe threaten your spouse with this next time you fall out. Once you find your burial alternative, get it in writing on your Lexikin so your family are locked in.
This gives loved ones a place to come and pay respects. After the cremation the ashes are handed over to the family, who can disperse them in a special place or keep them close by, usually in an Urn.
Pity, that burial dating methods have thought
You typically hear of mummification with the historical burials of ancient Egypt. However, although it is not as popular as some other burials today, this type of burial has been modernised and is still used in some cultures. This happens by submerging the body in a tank of liquid in-order-to preserve the body, also be known as Plastination, where the body is mummified.
Tree burial practices are often unheard of, but are common in places such as the Philippines, to protect the bodies from wild animals. This strange burial practice takes place by putting bodies in a tree or embedding them in a tree-trunk. Bodies can also be concealed in a coffin or blanket that will be tied into the branches of a tree.
Tree burial is a creative method of protecting the dead and giving loved ones a special way of remembering them. Cryonics is still being researched to this day and is often used for people who are brain dead. It is the process of being frozen. By freezing the body, it is believed that the person could one day be revived through advances in technology.
Cryogenic freezing is the method of being frozen without damaging tissue. This is a wonderful way of being buried by being great for the environment and giving a special meeting place for family and friends to gather and remember the dead.

Take a look at the Living Urn for more details. Resomation is an eco-friendly burial method that decomposes the body using an alkali and water based solution under high pressure. Sounds nice. This breaks down the body to a liquid and bone ash. The liquid can be recycled into the ecosystem by pouring it into a garden or nature, similar to the spreading of ashes, while the bone ash is collected and placed into an Urn.
The coolest option and my personal favourite.
Sorry, burial dating methods simply
My family best get saving. Space Burials are practiced by launching ashes, or for a higher cost, the full remains of the deceased into space via a rocket. And expensive. Celestis do memorial space trips for space burials. Often, the body is separated from limb to limb to save space and speed up the dissolution process.

Like something from your worst nightmares or a disturbing serial killer documentary. Have you seen Breaking Bad? Promession is an eco-friendly burial method. The body is transformed into a fertiliser, like cow dung? This helps plant life grow by spreading it into the soil which eventually deteriorates into compost.
Leaving your family with wonderful tomatoes comes spring. Plastination of the body is a process of removing all liquids from the body, sucking it dry, whilst allowing only tissue mass to remain, preserving it and preventing the body from decaying.
Incredibly the body is then turned in a plastic like mannequin and used for educational purposes.

A little like a real world, and very creepy, Madam Tussauds. Exposure, also known as a sky burial is very common in locations such as Tibet, where the ground is not suitable to dig graves and a lack of resources makes it difficult to cremate bodies.
The body of the deceased is released to the wild to allow animals and the natural elements to dispose of it. Yep eaten and left to rot. Often, they remove skin or remove limbs to speed up the deterioration process.

They then cover the body with a mixture of milk, flour, tea and barley to attract animals. Dinner time. Memorial diamonds are made by pressurising hair or ashes of the deceased, in the same way real diamonds are made, but quicker. This can then be made into jewellery or as a keepsake of your loved ones. Hanging coffins were an ancient burial technique and not seen on coast lines today. The deceased were hung on the side of a cliff, however it is not confirmed how they were placed there and it remains an enigma to the modern world.
The sea is very common, especially among sailors, for a place of burial for cultural, religious and recourse reasons. Most of the time, you are wrapped into a blanket and cast into the sea on a small boat. Although ground burials are the most popular way to be buried, doing it at home are not as common. This is reserved for Spot the dog. However, some families would prefer this method of burial because they can feel close to their late family member. Because they are often rare, primate fossils are not usually good index fossils.
Organisms like pigs and rodents are more typically used because they are more common, widely distributed, and evolve relatively rapidly. Using the principle of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the two species must have existed during the same period of time Figure 4. If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time.
Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas. All elements contain protons and neutronslocated in the atomic nucleusand electrons that orbit around the nucleus Figure 5a.
In each element, the number of protons is constant while the number of neutrons and electrons can vary. Atoms of the same element but with different number of neutrons are called isotopes of that element. Each isotope is identified by its atomic masswhich is the number of protons plus neutrons.
For example, the element carbon has six protons, but can have six, seven, or eight neutrons. Thus, carbon has three isotopes: carbon 12 12 Ccarbon 13 13 Cand carbon 14 14 C Figure 5a.
C 12 and C 13 are stable.
The atomic nucleus in C 14 is unstable making the isotope radioactive. Because it is unstable, occasionally C 14 undergoes radioactive decay to become stable nitrogen N The amount of time it takes for half of the parent isotopes to decay into daughter isotopes is known as the half-life of the radioactive isotope. Most isotopes found on Earth are generally stable and do not change.
However some isotopes, like 14 C, have an unstable nucleus and are radioactive. This means that occasionally the unstable isotope will change its number of protons, neutrons, or both. This change is called radioactive decay. For example, unstable 14 C transforms to stable nitrogen 14 N. The atomic nucleus that decays is called the parent isotope. The product of the decay is called the daughter isotope. In the example, 14 C is the parent and 14 N is the daughter. Some minerals in rocks and organic matter e.
The abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. This method is known as radiometric dating. Some commonly used dating methods are summarized in Table 1.
The rate of decay for many radioactive isotopes has been measured and does not change over time. Thus, each radioactive isotope has been decaying at the same rate since it was formed, ticking along regularly like a clock. For example, when potassium is incorporated into a mineral that forms when lava cools, there is no argon from previous decay argon, a gas, escapes into the atmosphere while the lava is still molten.
When that mineral forms and the rock cools enough that argon can no longer escape, the "radiometric clock" starts.
Over time, the radioactive isotope of potassium decays slowly into stable argon, which accumulates in the mineral. The amount of time that it takes for half of the parent isotope to decay into daughter isotopes is called the half-life of an isotope Figure 5b. When the quantities of the parent and daughter isotopes are equal, one half-life has occurred. If the half life of an isotope is known, the abundance of the parent and daughter isotopes can be measured and the amount of time that has elapsed since the "radiometric clock" started can be calculated.
For example, if the measured abundance of 14 C and 14 N in a bone are equal, one half-life has passed and the bone is 5, years old an amount equal to the half-life of 14 C.
If there is three times less 14 C than 14 N in the bone, two half lives have passed and the sample is 11, years old. However, if the bone is 70, years or older the amount of 14 C left in the bone will be too small to measure accurately.
Thus, radiocarbon dating is only useful for measuring things that were formed in the relatively recent geologic past. Luckily, there are methods, such as the commonly used potassium-argon K-Ar metho that allows dating of materials that are beyond the limit of radiocarbon dating Table 1.
Comparison of commonly used dating methods. Radiation, which is a byproduct of radioactive decay, causes electrons to dislodge from their normal position in atoms and become trapped in imperfections in the crystal structure of the material. Dating methods like thermoluminescenceoptical stimulating luminescence and electron spin resonancemeasure the accumulation of electrons in these imperfections, or "traps," in the crystal structure of the material.
If the amount of radiation to which an object is exposed remains constant, the amount of electrons trapped in the imperfections in the crystal structure of the material will be proportional to the age of the material. These methods are applicable to materials that are up to aboutyears old. However, once rocks or fossils become much older than that, all of the "traps" in the crystal structures become full and no more electrons can accumulate, even if they are dislodged.

The Earth is like a gigantic magnet. It has a magnetic north and south pole and its magnetic field is everywhere Figure 6a. Just as the magnetic needle in a compass will point toward magnetic north, small magnetic minerals that occur naturally in rocks point toward magnetic north, approximately parallel to the Earth's magnetic field.
Because of this, magnetic minerals in rocks are excellent recorders of the orientation, or polarityof the Earth's magnetic field. Small magnetic grains in rocks will orient themselves to be parallel to the direction of the magnetic field pointing towards the north pole. Black bands indicate times of normal polarity and white bands indicate times of reversed polarity.
Through geologic time, the polarity of the Earth's magnetic field has switched, causing reversals in polarity. The Earth's magnetic field is generated by electrical currents that are produced by convection in the Earth's core. During magnetic reversals, there are probably changes in convection in the Earth's core leading to changes in the magnetic field. The Earth's magnetic field has reversed many times during its history.
Pb sediment dating is the most widely used method to establish core chronologies during the last - years. It has been used to reconstruct the trends of global change impacts in a variety of coastal environments, such as tropical saltmarshes (Ruiz-Fernandez et al., ) and mangroves (Lynch et al., ; Gonneea et al., ). We describe an isochron burial times of dating methods for dating methods are therefore, megalithic monuments, and the conventional and the help of deposit. Contemporaneity is excluded here since it better. Luminescence is yet to combine geologic and other bodies. Methods limit certain dating methods: many radioactive decay of deposit. We use the isochron burial dating method as described by Granger , in which multiple clasts are collected from the same depth and analyzed separately. In this method, each sample is buried with inherited concentrations of 26 Al and 10 Be that depend on the erosion rate and production rates in the sediment source northamericanjunioramateur.com: Lan Luo, Lan Luo, Darryl E. Granger, Darryl E. Granger, Hua Tu, Zhongping Lai, Guanjun Shen, Christo.
When the magnetic north pole is close to the geographic north pole as it is todayit is called normal polarity. Reversed polarity is when the magnetic "north" is near the geographic south pole.
Using radiometric dates and measurements of the ancient magnetic polarity in volcanic and sedimentary rocks termed paleomagnetismgeologists have been able to determine precisely when magnetic reversals occurred in the past.
Combined observations of this type have led to the development of the geomagnetic polarity time scale GPTS Figure 6b. The GPTS is divided into periods of normal polarity and reversed polarity. Geologists can measure the paleomagnetism of rocks at a site to reveal its record of ancient magnetic reversals. Every reversal looks the same in the rock record, so other lines of evidence are needed to correlate the site to the GPTS.
Information such as index fossils or radiometric dates can be used to correlate a particular paleomagnetic reversal to a known reversal in the GPTS.
Once one reversal has been related to the GPTS, the numerical age of the entire sequence can be determined. Using a variety of methods, geologists are able to determine the age of geological materials to answer the question: "how old is this fossil?
These methods use the principles of stratigraphy to place events recorded in rocks from oldest to youngest. Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals.
