Rapid Growth of Magnesium-Carbonate Weathering Products in a Stony Meteorite from Antarctica
1 National Science Foundation Accelerator Facility for Radioisotope Analysis and Department of Geosciences, University of Arizona, Tucson, AZ 85721.
Nesquehonite, a hydrous magnesium carbonate, occurs as a weathering product on the surface of the Antarctic meteorite LEW 85320(H5 chondrite). Antarctic meteorites have resided on the earth for periods of 104 to 106 years, but the time needed for weathering products to form has been uncertain.
