Optical dating sediments
Although biotite is not very resistant to weathering and transforms into clay minerals, it is sometimes found in sediments and sandstones.
The best way to learn about minerals is to study with a collection of small specimens that you can handle, examine, and observe their properties.
It has become a common sight to see popular fossils such as those of Stegosaurus and Tyrannosaurus Rex in museums, but what is much less known are the many strange and bizarre fossils which paleontologists have discovered, especially recently.Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks.These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others.First they look very boring and it needs some discipline for a layman to work through them. 19 - Achat Christian Weise Verlag, München, 2000 ISBN 3-921656-54-0 Christian Weise (editor) extra Lapis No. Fowler The Solid Earth - An Introduction to Global Geophysics Cambridge University Press, Cambridge, 2004 ISBN 0-521-89307-0 Brian J.

Though there are plenty of bones on this list, we’ve also included a host of other bizarre fossils. Oh, we did.) You’ll likely be shocked at some of the weird fossils on this list; ones that unfortunately don’t get as much media attention as they should, such as a turtle the size of a helicopter and an ancient arthropod orgy.
