Stereo Photomicrographs

These photos were taken using a MBC-10 stereo microscope.  One photo was taken, then the specimen was moved over without rotating, and a second photo was taken.  Trial and error was used to determine the separation distance for gaining optimal stereo effect.  Magnification is not given here as it is monitor specific.

About the photos:

• botjade: This is a specimen of rare botryoidal jade (nephrite) from the Blue Moon Mine, Trinity Co., California.  More specimens can be seen at U.S. Jade.
• calcitecluster: This calcite cluster is from a quarry in the Lexington Limestone at Danville, KY.
• dogteeth: This is another calcite cluster with doubly terminated dog tooth spars, Mexico?.
• pyritetetras: Tetrahedral crystals of pyrite on fluorite, Santa Barbara Mine, Chihuahua, Mexico.  Field of view is 7mm.
• pyritohedron: A typical form of pyrite from Spain.
• gravesmthematite: This a specimen of hematite from Graves Mt., Georgia.  The hematite is in the form of clusters of concentric shells.
• lichen1: Rhizoplaca chrysoleuca.  On granite boulder, Laramie Mts., WY.  Field of view is 5mm.
• lichen2: Rhizoplaca chrysoleuca.  Field of view is 20mm.
• lichen3: Ramalina americana with apothecia.  On black locust branch, Woodford Co., KY.  Field of view is 2mm.
• galena: Galena on sphalerite.  Field of view is 10mm.
