So, ...what then in the Plate Tectonic consensus exactly *is* the
explanation for a progressive global marine regression resulting in
the laying bare of thousands of metres of build-up of Phanerozoic
stratigraphic sequence across continental crust world- wide, and

Geology professor John McCampbell once wrote: ?The essential
differences between Biblical catastrophism [the Flood] and
evolutionary uniformitarianism are not over the factual data of
geology but over the interpretations of those data. The

We thought you would be interested to know about the renewed
availability of Keith Richards' seminal book in the field of fluvial
geomorphology, "Rivers: Form and Process in Alluvial Channels."
The 1985 edition of this landmark book has just been returned to print

 Where did all the water come from to cover the whole earth? The
Bible itself answers. Early in the creation process, when the expanse
of the atmosphere began to take shape, there came to be “waters . . .
beneath the expanse” and “waters . . . above the expanse.” (Genesis

earth's crust and the underlying mantle, averaging 8 kilometers (5
miles) in depth under the oceans and 32 kilometers (20 miles) in

We have just moved in to a house on the edge of marshland in the
eastern UK
The house has mains drinking water, but there is a 3' 6" (approx 1m)

Richard,
thanks for the information about the fictitious paleo-ocean.

centered on the P-T boundary involves the large-scale dynamics of the

Below is a link to a story re a professional paper, with link to same, about
"Silent Slip" in/on Sub-Duction Zone Faults. This paper is based on studies
of the Nankai Trough & Cascadia Sub-Duction Zones.

In other newsgroups, the movie _The Day After Tomorrow_ has triggered
discussion of ice ages.  (Yes, the movie is bullshit.  Take that as
said and move on.)  I had a few questions that I was hoping
a geologist could answer:

A few days ago, on a TV quiz show, the question was asked: “Which is the
only continent that does not have a continental divide?”  The answer was -
Antarctica.  I work in an office full of geologists and we can’t figure that
out.  We’ve tossed around thoughts about radial flow, only ...

Synopsis of the evolution of the Verneshot hypothesis
Alvarez proposed that the impact of a meteorite caused the extinction
of the dinosaurs at the end of the Cretaceous period.  His geologic
survey of the Cretaceous-Tertiary (K-T) boundary revealed that it was

Does anyone know where the pictures of maroon and white Navajo Sandstone I
keep seeing were taken?  My wife would very much like to get some pictures
on our next trip.
5 1/2 days and something like 450 digital and 100 film shots and she still

For those still looking for an un-earthly origin for the Mars spherules --
spherules just like the ones seen in the Mars photos are still alive and
well in the Navajo Sandstone at Zion, Escalante/Grand Staircase, and Capitol
Reef .
