Geology is the study of Earth history, structure, composition and life forms.
This category is for the topic of geologic time and techniques and tools to measure geologic time.

Sites discussing the age of the earth from a Biblical perspective, including discussions of interpreting scientific observations to support the Genesis account of creation and earth history, do not belong here. Submit them to Society/Religion_and_Spirituality/Christianity/Perspectives/Origins_and_Creation

This category is for geology books, magazines, and journals.
This category is for any organization or association specifically related to, or promoting the earth sciences.
Web sites pertaining to the use of Geology in the Oil and Gas Industry. Any activity that does not fit into an existing subcategory is listed here.
In general this category includes web sites of interest to research scientists as well as oil and gas geologists. If a business deals only with the commercial (not scientific) aspects of the oil and gas business, it should be submitted to a category under Business: Industries: Energy: Oil and Gas.
The study of rocks, which are aggregates of minerals.
Most research activities will either occur in academic departments or in research institutes (which may either be in universities or external). Both of these are included in this category.
