NWA 6704 Meteorite Thin Section

NWA 6704 is a special meteorite which has properties that make it difficult to place in any known category of classification. The story of its discovery by Gregory M. Hupé is a feature article at Meteorite Times and provides a nice look into the art of meteorite discovery. Slices showing the internal meteorite texture have an eerie green coloration… in fact, it makes me think of kryptonite! This thin section of NWA 6704 is composed of large orthopyroxene oikocrysts which, due to their intricate polarized color gradients, were difficult to seamlessly stitch together. The final result is rainbow of vivid colors, patterns etched almost 4.52 billion years ago. Be sure to view the links below for additional information and images.

NWA 1950, a poikilitic shergottite, is a Martian treasure for meteorite collectors. The two thin sections presented in this post are stunningly beautiful and were a real joy to photograph. I hope viewers find them visually stimulating. Many of the darkened olivine grains look remarkably similar to those found in NWA 2737; both were formed from high pressure shocks related to the ejecting event. Image One was taken with 4x/0.25 objective while Image Two was taken with 10x/0.25 objective. Additional information:

NWA 5903 Meteorite Thin Section

This thin section image of NWA 5903 provides viewers with an abstract painting created by nature. To look at a thin section of any rock under cross polarized light is to view the emergent features of mineral formation. Sextillions upon sextillions of atoms all interacting! It is fascinating to observe how matter crystallizes in various geometries and how this crystallized matter acts under polarized radiation. The eucrites are always wonderful to view this natural process, and NWA 5903 does not disappoint. The calcic plagioclase and exsolved pyroxene are mostly what give this image its incredible beauty.
