D’Orbigny Meteorite Thin Section

This is a thin section specimen of the D’Orbigny Meteorite. The thin section photographs were taken under cross polarized light using two linear polarizing filters. The first set of pictures is from a nicer CCD and microscope. For a good link to more Angrite pictures, see here. Angrites always look spectacular in polarized light.

Pasamonte Meteorite Thin Section

Taken in cross polarized light, this is a remarkably beautiful thin section of the Pasamonte Meteorite. The Pasamonte Meteorite is famous in history as the first observed fall to be photographed. Harvey Nininger played an important role in cataloging and recovering many of the specimens currently located in museums and private collections. The Pasamonte Meteorite is described here as:

a brecciated, non-cumulate, polymict eucrite, showing dark fine-to medium-grained, subhedral to euhedral, lithic and mineral fragments set in a light, friable, sugary, ash-gray matrix with a high porosity
