Hundreds of impact craters on Mars contain diverse phyllosilicates, interpreted as excavation products of preexisting subsurface deposits following impact and crater formation. This has been used to ...
Rivers discharge a constant supply of sediment into the world's oceans. This sediment is largely composed of various clay minerals - the products of rock weathering - and organic compounds of plant ...
According to this idea, the phyllosilicates formed as products of magmatic degassing of volatile components on short timescales. In support of this suggestion, Meunier et al. note that the ancient ...
Figure 1: CRISM and laboratory reflectance spectra showing hydrated silicate mineral diversity. A new class of hydrated silicate has been identified (spectrum 2 in Fig. 1b), characterized by a ...
