Petrography and Field Mapping of Eocene Intrusions and Adjacent Breccia Zones at the Scraper Springs Prospect, Elko County, Nevada
… mapping techniques to document the geology and alteration of the diorite intrusion and adjacent silicified/advanced argillic lithocap breccias. Petrography and sodium-cobaltinitrite staining supplement field observations to aid in understanding alteration events. Geochemical data from topaz-rich …

Geology, petrology and geochemical characteristics of alteration zones within the Seridune prospect, Kerman, Iran
… The early chlorite epidote (propylitic) alteration zone at the Seridune prospect shows a general enrichment in Mg and Ca, which is consistent with the presence of clinochlore, epidote and calcite. The XMg of chlorite decreases from the proximal to distal portion of the chlorite epidote …

Volcanic, structural, and hydrothermal controls on coincident Archean Low and High Sulfidation VMS Systems within the Onaman Assemblage, Onaman-Tashota Greenstone Belt, Northern Ontario, Canada
… and domes. The assemblage hosts a metamorphosed alteration system defined by kyanite and chloritoid-bearing mineral associations that overprint more traditional VMS associations of calcite, chlorite, and sericite. The sequence is consistent with subaqueous volcanism followed by uplift and …
