Is this magnetic or a paramagnetic phenomena? I never took geology. It's been too long from general physics and physical chemistry.

Anerobes are responsible for the Hydrogen Sulfide in crude oil recovered from as deep as 15,000 feet, and reservoirs have been known to become contaminated with them and the oil become 'sour' (and less desireable as a result).

Who knows what critters are down there?

The iron compounds are magnetic because they are lined up with the earths magnetic field. As the bacterial use the mineral as part of their life cycle the magnetic property of the rock decreases.

The only beef I have with this article is the use of the therm “magnetic signal”, it would have been more correct to call it “magnetic flux”.

Thanks neverdem. X-Planets, related to the collateral interest in panspermia.

	Gods Graves Glyphs	Thanks neverdem. [M]any bacteria live deep in the oceans and deep in the earth, far from light, far from what we normally think of as good, comfortable places to live... the bottom of the Mariana Trench... 11 kilometers (almost 7 miles) below the surface of the sea... there are bacteria. Some of them won't grow at all unless the atmospheric pressure is at least 50 megapascals (around 7,000 pounds per square inch), and they grow better if the pressure is greater -- 70 megapascals (more than 10,000 pounds per square inch). For comparison, the pressure at sea level -- the pressure we have evolved to bear -- is 700 times less. Then there are the "intraterrestrials" -- the organisms that live in rocks deep in the earth, the creatures of the "deep subsurface biosphere." Bacteria have been found in rock samples taken several hundred meters below the sea floor, even when the sea floor itself is 4 kilometers (2.5 miles) below sea level. Thomas Gold-related.

an oldie excerpt from the hard drive:

Microbes May Thrive Under Pressure
by W. B. Schomaker

"Carnegie Institute scientists Anurag Sharma and James Scott found that E. coli remained viable, despite being squeezed with pressure exceeding 16 thousand times that found at sea level. This means the bacteria could endure pressure conditions like those found 31 miles (50 kilometers) below Earth's crust and perhaps much deeper below the surface of an alien ocean. Previously, scientists believed that only highly specialized organisms, called extremophiles, could thrive in such intense conditions."
