    Abstract

    Bulk and grain densities, porosities, and magnetic susceptibilities of 67 individuals of Kosice H chondrite fall were measured. The mean bulk and grain densities were determined to be 3.43 g/cm(3) with standard deviation (s.d.) of 0.11 g/cm(3) and 3.79 g/cm(3) with s.d. 0.07 g/cm(3), respectively. Porosity is in the range from 4.2% to 16.1%. The logarithm of the apparent magnetic susceptibility (in 10(-9) m(3)/kg) shows narrow distribution from 5.17 to 5.49 with mean value at 5.35 with s.d. 0.08. These results indicate that all studied Make meteorites are of the same composition down to g scale without the presence of foreign (non-H) clasts and are similar to other H chondrites. Kosice is thus a homogeneous meteorite fall derived from a homogeneous meteoroid. (C) 2014 Elsevier Ltd. All rights reserved.
