Density and porosity are fundamental physical properties of meteorites. These data shed light on the origins, processes, and evolution of meteorite parent bodies and provide ground-truth data on asteroids. As part of an ongoing project to catalog densities and porosities of meteorites, we measured these properties on a number of samples in the collection at the American Museum of Natural History (AMNH) in New York. In addition, it is important to know the extent to which these properties may vary within one particular fall. AMNH holds a significant number of fragments of the CV chondrite Allende, yielding numerous individual pieces. By measuring density and porosity of as many of these pieces as possible, we get and indication of the degree of uniformity of the fall.
Bulk densities were measured using the glass bead method [1,2]. Grain densities were measured using a Quantachrome Ultrapycnometer helium pycnometer, and porosities were calculated from the bulk and grain densities. We will report on density and porosity measurements of approximately 30 different chondrites of various classifications, many of which consisting of more than one piece. Bulk and grain densities were measured for at least 27 pieces of Allende, as well as 8 pieces of the CK meteorite Karoonda.
