How is mariposite formed
WebZeolite minerals occur in sedimentary, metamorphic, and igneous rocks, almost exclusively as alteration products. Most form at temperatures less than 250 °C and at depths less than 10 km in water-saturated environments. This environment represents the zeolite facies, the lowest grade of metamorphism (Fig. 8).With increasing sediment burial, diagenetic … WebThe ore is dominated by carbonate (probably dolomitic or ankeritic, minimally acid-reactive, roughly 62 vol.% of the rock), quartz (30%) and green mica (8%). Accessory minerals include arsenopyrite, chalcopyrite, pyrite and rutile. The ore is relatively low-grade, probably 1.3-1.5 ppm gold, whereas associated `porphyry' ore may grade 5-6 ppm.
