Rock-forming Minerals in Thin Section, 6H35.54
Topic and Concept:
Polarization, 6H35. Birefringence
Location:
Cabinet: Optics (OP)
Bay: (B5)
Shelf: #2
Abstract:
Three examples of rock-forming minerals in thin-section were kindly donated to UW Physics Lecture/Demonstration by the UW Geology Department.
Preparation and examination of thin sections is a topic in optical mineralogy, and is typically covered in the undergraduate geology major's coursework.
The thin sections are approximately 30 microns thick, and mounted on glass slides so they can be handled.
