With all due respect. Grey hematite is simply a form of iron oxide
Fe2O3 . It can form from water but it also can occur in volcanic rocks,
metamorphic rocks. It is not "mostly" formed in the presence of water.
Does anyone have a lit. reference of the geochemistry and kinetics for
the formation of hematite as masses of large crystals? Maybe the USGS
would be kind enough to provide one.

Now that one lander has identified one rock ("Adirondak") as an
olivine basalt, olivine has been detected locally in the soil and also
from orbiter. That rock is very anguylar and doesn't appear to polished
to a high luster by wind driven material.

With the presence of ubiquitous olivine and unweathered basalt, it is
unlikely that liquid water (as opposed to ice and vapor) has occurred on
the surface of mars for a long long time. Absent water, absent water
based life, and so no coal. The geomorphology of mars need not be
sculpted by water. Dry debris flows and avalanches can be just as
effective given time.

Before the Apollo program, NASA went through intricate gyrations to
"prove" (aided and abetted by the USGS) that most of the lunar craters
were of volcanic origin--a concept not seriously entertained since the
time of Barrelle. And NASA now still has an low level of imagination
being guided by the Geological Survey.


The mossbauer spec and other instruments shoud be able to detect
carbon. If coal dust covered the surface it should have been
detected. I know of no reason to suspect coal on mars. If it did, we
should have to radically revise our theories of the formation of the
planets. IMHO it would be more likely to find carbon dust on the
surface in the form of micro-diamonds.

Robert, I wonder if diamonds can be formed from a meteor or bolide
striking Mars from Nonbio-carbon such as limestone.

Limestone is CaCO3, not concentrated carbon, you idiot.

I guess I would
also need to know how much connected is limestone to that of
biological matter. So, would the Moon have tiny diamonds from all of
its formed craters even if it is lifeless. I need to know whether
diamond creation occurs on all planets that have meteor impacts?

And if meteor impacts create diamonds regardless of whether the planet
has life or has no life, whether there is some distinguishing
characteristics between diamonds formed from meteor impacts upon
biological-carbon or nonbio-carbon.
I recall the Arizona meteor crater had thousands of very tiny diamonds
and that Arizona was rich in biocarbon lifeforms when the meteor
struck. But that a meteor impact in Africa created some of the largest
and finest diamonds because it was lush in bio-life at the moment of
impact.

So I need to get some data on meteor created diamonds and whether
diamonds can be formed from meteors impacting coal seams and whether
those diamonds have a unique signature as per the coal origin.

Also I am wondering whether Manganese Nodules would have formed on
Mars if Mars had vast Oceans some 6 to 8 billion years ago. I suspect
if manganese nodules are found would be proof of vast oceans and also
we would be able to give parameters of those oceans because Manganese
Nodules have a means of dating their accretions.
