What happens to a pile of blood in the middle of nowhere?

Question

as it dries over millions of years and is buried by new layers of rocks, and earth and compressed over millins of years. Ive read somewhere that there is a theory out there that says iron deposits are formed from blood. can anybody explain this to me and the logic behind it, or why its not possible or whatever.

Answer 1

The blood would dry up, oxidize, and blow away. Prick your finger and drop some on your sidewalk and see what happens to it.

Answer 2

The major source of iron deposits is when the oceans "rusted" about 2 billion years ago.  

This was because the oxygen level in the ocean water reached a critical level.  Before that the ocean water was "hard" water - it had a lot of iron in it.  Chlorophyll containing bacteria in the oceans created oxygen and caused the dissolved iron in the oceans to oxidize and precipitate out as thick bands of what is today iron ore.

No blood to iron and no dinosaurs to oil.

Answer 3

The operational chemical in blood is hemoglobin,  whose main component is iron; hence the name, "hemo", as in "hematite" (an iron ore).

Answer 4

Don't listen to Dan. Pricking your finger could cause infection if you aren't trained or using sterilized equipment, plus its just a horrible experiment. What if you are anemic?

There is iron in blood however which could pool, if the moisture from the blood evaporates which would leave the iron and the remainder of blood would coagulate dry up and turn into a powder/flakes.
