内容記述 | Secondary minerals and evaporites around Lake Vanda, Wright Valley have been identified by X-ray diffraction techniques in order to investigate the areal distribution of these minerals. Gypsum is the most abundant mineral near the shoreline of Lake Vanda and halite is the most abundant mineral in the elevated areas. Secondary minerals are abundant on the Dais indicating low-grade hydrothermal metamorphism of the dolerite. Based on the distribution of evaporites, the authors propose that the origin of magnesium and potassium ions in lake water may be clarified by the value of Mg/K, that is, magnesium and potassium ions with Mg/K value less than 4 originated from the weathering of rocks plus sea spray, while those with the value greater than 4 originated from sea water. | |||||
