Indiana Limestone (PowerPoint)

At Camp Brotherhood 2010 Michael Yeaman gave a powerpoint presentation (some would call it a "short show") on "The Geology of Sculpting Stone" which you can download (it's big 20 Meg) and browse thru and review at your own pace.

Michael has since prepared similar "The Geology of Sculpting Stone" presentations for Basalt and Granite following the same format:

•The Stone Defined
     ◦— General Description, History of Use and Physical/Chemical Properties
     ◦— Specimens (macro and thin section)
     ◦— Specific Occurrences
•Geology
     ◦— Age and Geologic Description
     ◦— Formation Environment and Processes
     ◦— Global Paleogeographic Setting
     ◦— Modern Analogs
•Select Creations
     ◦— Art
     ◦— Architecture
