Geology, geochronology, and geochemistry of the Sinongduo Ag-Pb-Zn deposit in the Gangdese metallogenic belt: Implications of intermediate sulfidation mineralization in the Linzizong volcanic succession

摘要

The Sinongduo Ag-Pb-Zn deposit was first defined as a typical low sulfidation (LS) epithermal deposit in the widespread Linzizong volcanic succession (LVS), Gangdese belt, Tibet. This paper we describe the lithology, mineralization, and hydrothermal alteration based on current advances in exploration, and use multiple chemical and geochronology methods, including whole-rock geochemistry (major and trace elements) of ores and the lithocap, the mineral chemistry of sphalerite, and the LA-MC-ICP-MS zircon U-Pb dating of host volcanic rocks to better constrain the genesis of the Sinongduo deposit and give some exploration advice.
