Careful, Steve, you're starting to sound like Kent Hovind. :-)

The Clinton iron ore is a Silurian red hematite that stretches from
Alabama to New York. It runs about 35-40% iron, compared with about
50-60% iron in the specular hematite we get from South America. The
Clinton is a fossiliferous, shallow-water deposit, possibly originating
from the weathering of mafic igneous rocks (according to Longwell, Flint
and Sanders, _Physical Geology_, 1969, p586).
I suppose if Art's idea is correct, then there should have been massive
plantonic blooms during the Silurian. Does this time correlate with an
episode of oil production, Glenn?
