What percentage of the Earth's crust is made up of organic material? - best rated organic underarm deodorant
I wonder what percentage of the Earth's crust is composed of organic material (plants and animals died, alias) of the ground?
Even if by chance you know ... What is the rate at which expanded with the organic matter on Earth and deepened?

Interesting question. There are several types of organic matter in the crust on the soil or sediment organic and bio-fuels (coal, oil) to lower levels. I assume that the total amount must be small organic matter in the crust, but here is an attempt to put some numbers behind it:
A high content of organic matter in soil is an average of 5%, and the soil layer is only a few feet deep. Let us assume that the level of the ocean sediments and organic matter similar to the deeper soil layers. Therefore, we assume that there is a depth of the soil or sediment, an average of 10 meters. This leads to an average depth of 50 cm of organic matter in soil / sediment layer.
Coal is the most important component of organic fuels. A region rich in coal multiple seams, each seam tens of meters thick, so we assume a total depth of 100 meters. Perhaps 1% of the surface of the earth has such rich resources of coal, and covers the entire surface of the earth, this would lead to an average depth of 1 meter of coal. *
The thickness of the crust varies from about 5 km on the seabed about 40 kilometers of the earth, and no part of the ocean about 3 times more than the earth, then say that all crustal rocks average depth of 15 km.
With the above assumptions, which are moving deliberately toward the positive side, a first approximation to the organic matter content of the crust would be: (.5 m of soil organic matter of fossil + 1.0 m) / (15.000 m) = 0 , 0001
Thus, as the upper limit, perhaps 0.01% of TCrustal material would be organic.
....
Another answer in this case, we examine the question of a geologically and contains limestone as organic, because organic matter is derived, what is true. However, in chemical terms, limestone (CaCO3) is generally considered to be inorganic because they do not contain carbon-hydrogen (CH) Bond. And in biology, including the inorganic carbon are considered, because it is biologically active. Unfortunately, the distinction between organic and inorganic is, is .... in some cases a matter of definition

.... and if the answer to your question also depends on the definition of "organic" is more relevantVant to your problem.
Limestone is, in fact, most of the crust consists of organic material. My calculations show that about 0.3% by volume alone. Other organic matter, probably no more 0.1% vol.
The soil is a much smaller proportion of organic matter on the planet, even if the reservoir of carbon is very important to their role in global climate and short-term global carbon cycle. The soil varies from 0-99% organic matter. Not all areas on the planet is covered with earth. The content of the soil has a high organic is often very thin.
There are large stocks of organic matter in the crust of the earth. The larger the limestone. Other organic materials (in the cortex of oil and natural gas about 3 Trilliremain) in barrels. Many slate contain anywhere between 2-20% organic matter. Coal is a major reservoir of organic matter in the crust that almost 100% of organic matter.
From:
The American Geological Institute defines organic as a rock:
"A sedimentary rock, especially from organisms (plants or animals) and equipment that were originally part of the skeleton or tissue of an animal. Cf biogenic rocks.
By: Bates, R. and J. Jackson, eds, 1984, Dictionary of geological terms, page 359
Only the stored carbon in the limestone is 48000000 Gt.

The molecular weight of calcium carbonate in the amount of "bio-making Rock" in the C --Rust, is the amount
Gigatons 400,000,000. A gigaton is one billion tonnes.
Assuming an average density of limestone is 2.71. This value is typically used deep log analysis of calcium deposits. This calculation produces a volume of approximately 150,000,000 cubic miles of limestone, or about 35,400,000 cubic miles.
Well, the volume of the crust of the earth to be calculated, we have the area 510,065,600 km2. Cut Assuming an average thickness of the crust of 100 km, the volume of the crust is 510,065,600,000 kilometers dice. Share (the amount of limestone which is by far the largest amount of organic material on Earth) and received 0.29 or 0.3% of the organic crust material form of limestone.
Since the estimates that we have 3 trillion barrels of oil left on Earth, which converts to 477 million cubic meters, or 477 cubic miles. What other very small percentage added.
For all the coal remained in the country is estimated at 984 million tonnes. It's proven reserves and is much more that was not found. It is 1.3 tonnes of coal in a cubic meter. This results in a volume of coal in the crust up to 1,500 cubic kilometers, even a very small percentage of the cortex.
It is difficult to say that it is a model for the "speed with which the biological material ... expanded or deepened. Organic materials such as coal, petroleum, natural gas tends to be altered by the depth andTemperatures on some changes in their entirety with the inorganic carbon as graphite.
***********
Edit: I guess the thickness of the crust is probably much higher than the model shows the crust of the USGS, it can be, how on average 20-30 km. This simply means that my final estimate is almost at 0.9% for only lime, and the total could be above 1%.
I can not finalized. " But I can say that very, very small.
