Discovery of Lorandite TlAsS2 at the Distal Au-Tl Deposit in a Skarn system, Fengshan Area, Middle-Lower Yangtze River, Eastern China

摘要

Objective Thallium has been used as an indicator element in geochemical exploration of searching for hydrothermal gold deposits.However,the T1 minerals and mineralization are rare in nature.Lorandite TlAsS_2,a relatively uncommon mineral,has been dominantly discovered in some Carlin gold deposits,and minor SbHg,U and Pb-Zn-Ag deposits.It is of a hydrothermal origin and was typically formed at relatively low temperatures.The relationships between these deposits containing lorandite and intrusions remain a
