Key Points

This research aims to analyze trace element compositions in sphalerites from specific lead-zinc deposits to understand their formation and mineralization processes.
Selected typical deposits, Songbaidong and Yangjiawan, in Zhenyuan-Taijiang area for analysis.
Utilized LA-ICP-MS for in-situ analysis of trace elements in sphalerites.
Combined geological features of the deposits with trace element characteristics to explore genesis.
Mineralization is primarily controlled by structural geology, with lead-zinc mineralization occurring in fractures and accompanying strong silicification.
Sphalerites are characterized by elevated levels of Ga, Ge, and Cd, while being poor in Co, Mn, Sn, Ag, In.
Estimated formation temperatures of the deposits range from 97 to 266 °C, indicating they are likely medium-low temperature hydrothermal vein type deposits.

Investigates trace element compositions in sphalerites of Pb-Zn deposits, suggesting mineral formation processes.
