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.

Equipment	Location	ID Number

Thin sections	OP, Bay B5, Shelf #2
polariscope	OP, Bay B5, Shelf #2

Setup and Procedure:

Place thin section between crossed polarizers of polariscope.

Rotate one polarizer (or look at thin section from different vantage point)

Obseve the changes of the colors, which are frequently quite beautiful.

Cautions, Warnings, or Safety Concerns:

Discussion:

Discuss the physics behind the demonstration, explaining some of the various steps of the demonstration when appropriate.

Videos:

Lecture Demonstration's Youtube Channel
