2010. Enstatite chondrite density, magnetic susceptibility, and porosity
Abstract-As part of our continuing survey of meteorite physical properties, we measured grain and bulk density, porosity, and magnetic susceptibility for 41 stones from 23 enstatite chondrites (ECs), all with masses greater than 10 g, representing the majority of falls and a significant percentage o...
