Totally by chance, while working further with John VanSickle's height_field
patchwork macro, I came across this landscape. I called it Drifting Over The
Traps.
For those who wonder what Traps are: this refers to the Large Igneous
Provinces, of which the Siberian Traps at the Permian-Triassic boundary, and
The Deccan Traps at the Cretaceous-Tertiary boundary are the most famous for
alledgedly being responsible for major global biological extinction events.
I shall probably work further on this, but I thought I would already share
this image with you.

Hey Thomas,
Interesting landscape. I bet 'The Traps' have some great potential for
good mineral hunting. That's assuming they harbor pegmatite dikes. If
the composition is mainly basaltic, then there's a good chance of
finding some zeolites. I've always wanted to find some apophyllite,
which is found with zeolitic minerals.
I haven't forgotten about the weathered rocks tutorial I've been
promising for months. I'm just not sure how to start new pages on the
POV Wiki yet...

The traps are basaltic indeed. I rapidly googled and found this:

or this one:

How about the Karoo, Sam? Smaller than the traps in Siberia or India, but
still a vast igneous province.

Would be nice... :-)
