此外，我知道这是可能不是石油泄漏，但我确实有证据表明有的东西正在发生，我只是试图排除这种可能性。谢谢你！< / p >

The other reason for no plant life is the land was purposely cleared using heavy equipment such as bulldozers or graders. The land may have been purposely cleared for other reasons: preparations for drilling of the site, to erect buildings or a similar facility or to accommodate soil heaps, as you have indicated. Do the soil heaps appear to be local soil from the site that has been removed and stockpiled or does it look like soil from elsewhere? How many dumps are there and what would you estimate to be the size of the dumps: length, width and height?

Any carbon in the soil could be natural, it could be charcoal that has been plowed in. It is unlikely that any hydrocarbon would have "decomposed/disintegrated" leaving carbon in the ground and hydrogen to escape to the atmosphere. If there were oil related hydrocarbons in the soil and it was in such quantities to kill the vegetation that was there you would possibly be able to smell it from the boundaries of the site. If the land was able to be dug one might be able to smell any liquid hydrocarbons in the soil.

As intriguing as your question is, there is not enough detail to give a conclusive answer.
