However, if Venus had had more water in the past, as the high D/H ratio implies, hydrous minerals might have formed. We present the first experimental study that examines the decomposition rate of hydrous minerals, specifically tremolite, with applications to Venus. We predict that tremolite can survive decomposition on Venus over geologic time scales at current and at higher surface temperatures. Thus, if future spacecraft can detect tremolite, this discovery could serve as evidence of a wetter Venusian history. (C) 2000 Academic Press.
