It's been a really interesting exercise, this sledging plate
tectonics...    (..the relationship between the knowledge base, how
it's maintained, and how the people who feed from it use it to go
clubbing - for *fun*)  ...

Q: The Big bang 14.8 billon Bp.  Earths age 5.2 billon Bp.

In an obscure thread in this ng that you Real Geologists wouldn't touch
with a ten-foot pole, this Don Findlay person wrote that plate tectonics
theory is "based on the assumption of a panthalassa." I wrote that that
is wrong. Plate tectonics theory is based on the assumption ...

Signs of intelligent life on Earth?
  I first got a link to this on an iPod site, of all places.
Paste this location in to your own 'Google Earth'
(nothing up MY sleeve ;^) and tell me what YOU think it is.

What do you call a bunch of geologists?
(Well, we're not carrots, so a 'bunch' doesn't really scan very well.)
A collection of geologists?
A stratigraphy of geologists?

How many rock types are there? My MacDonald Encyclopedia of Rocks and
Minerals
has 377 rocktypes including minerals. Would this be representative of the
bulk of most

These were taken in sunlight.
The actual green was a little darker than in the pics but is reasonably close.
The DSC rock is from California, USA.  Serpentine.

Does anyone have any suggestions, picture of amateur setups, websites
or references for preparing thin sections minerals, rocks and metals at

Any homemade equipment suggestions for saws, laps, grinders and

SCIENTISTS have found that Britain owes its island status to a
catastrophic flood that swept away in less than 24 hours the hills that
once joined the land mass to France.
The flood, which took place between 400,000 and 200,000 years ago,
