Nantan Meteorite Thin Section. The official record of the Nantan's fall was in 1516. The Location covers the towns of Lihu and Yaozhai, in Nandan County, Guangxi, China. The Nantan meteorites were distributed over an area of 27 - 28 -Km long and 8 -Km wide, overlying Permian limestone and surface soils. The occurrence of northwestern elongated zone concurs with the historical description of falling direction. Nantan meteorites have different shapes: spherical, triangle, flat-iron shaped, elliptical, semi-sheered, tongue-shaped, irregular, and so on. Fresh meteorite surfaces are black, and commonly characterized with angular or round melted pits. Because of severe weathering and the humid climate, most of the smaller pieces of the Nantan meteorite are rusty brown in color, with no sign of a melted surface. The average chemical composition is 92.35% iron, and 6.96% nickel. This Auction is for ONE 1x3" glass slide with a thin slice (section) of meteorite on it. The section is so thin that it allows light to pass through it. For best results, try looking at this through a microscope. We sell several microscopes, including high power compound as well as polarizing. Contact us for details: sales@livebloodlabs.com. |
