The"Great Unconformity" And Other Essays About Rocks and Fossils

The"Great Unconformity" And Other Essays About Rocks and Fossils

There is a great blog called "Written in Stone,
which has a number of great and well-illustrated
essays about geology. This includes a series
about the "Great Unconformity."

The Great Unconformity of the Grand Canyon
and the Late Proterozoic-Cambrian Time Interval:
Part I - Defining It
http://written-in-stone-seen-through-my-lens.blogspot.com/2012/01/great-unconformity-of-grand-canyon-part.html

The Great Unconformity and the Late Proterozoic-
Cambrian Time Interval: Part II - The Rifting of
Rodinia and the "Snowball Earth" Glaciations
That Followed
http://written-in-stone-seen-through-my-lens.blogspot.com/2012/02/great-unconformity-of-grand-canyon-part.html

The Great Unconformity at Baker's Bridge:
Part III - Regional Geological and Global
Bio-Evolutionary Significance

Lecture About Organic Rich Mudstones (Including Their Paleontology)

Lecture About Organic Rich Mudstones (Including Their Paleontology)

There is a wonderful, although long, lecture about
organic rich mudstones that can be viewed online.
It is “Organic Rich Mudstones-Questions” at:
https://www.youtube.com/watch?v=9GVdJAmf7FU

Although it aimed toward oil and gas exploration,
he does discuss the paleontology and taphonomy
of organic rich mudstone (“back shales”) in some
detail. What he has to say about the paleontology and
taphonomy of these rocks is quite interesting.

This lecture is just one of number of lectures that
the Houston Geological Society has online at
http://www.hgs.org/multimedia_Education

I also found interesting is “The Largest Volcano in
the World-Mid Pacific Ocean” by William Sager at:
