Enstatite chondrite density, magnetic susceptibility, and porosity

摘要: range from 0 to 12% with the majority less than 7%, and magnetic susceptibilities (in log units of 10 )9 m 3 kg )1 ) 5.30 5.64, an average 5.47. For finds, weathering reduces both grain bulk densities as well susceptibilities. On average, finds have much higher porosity falls. The two EC subgroups EH EL, nominally distinguished by total iron content, exhibit similar values for all properties measured, indicating metallic content in stones subgroups. We also observed considerable intra-meteorite variation, inhomogeneities at scales up approximately 40 g (approximately 12 cm ).
