Historical Geology: Web Research Discussion

Description

Research one of the following
questions on the Internet. Research sources of information on the Web can
include, but not limited to, books, articles, videos, and handouts.
1. 
What are the mineralogical and stability differences between the
carbonate minerals calcite and aragonite?
2. 
How have organic reefs differed over time in terms of dominant
organisms which make up their framework structures? Be sure to give a few
examples.
3. 
How is the inorganic precipitation of calcium phosphate
inhibited in most marine waters?
4. 
Some evaporite units are more than 2 km thick. How can such
enormous amounts of evaporative minerals accumulate? Note that evaporating the
entire Mediterranean Sea right now will produce only 60 m of salt deposits.
