- Sample Description
- ASD lab spectrum of sample BRCM1 from Big Rock Candy Mountain, Marysvale, Utah. XRD: Natural intimate mix of quartz, albite, gypsum, natrojarosite, pyrite, illite/muscovite. Proximal propylitic alteration from feeder zone. Weathered andesitic lava flows from pyritic, propylitically altered feeder zone of hydrothermal system formed at ~21 Ma (Miocene). Fine-grained, yellowish jarositic coatings on light grey, thoroughly altered rock.
