“…The giant South China Sb metallogenic belt has supplied >50% of the world's Sb metal resource (e.g. Wu, 1993 ; Fu et al., 2019b ). Despite of much attention received (e.g.…”

“…Despite of much attention received (e.g. Xiao, 2014 ; Fu et al., 2019a , 2019b ), the timing of Sb mineralization is still not well constrained. In this contribution, we use the Weizhai Sb deposit in the giant South China Sb metallogenic belt as a case study for LA-MC-ICPMS in situ U-Pb dating.…”

“…The giant South China Sb metallogenic belt covers an area between the Yangtze Block and the Cathaysia Block and is a part of the South China low-temperature metallogenic domain ( Figure 1 A; Hu et al., 2017 ). This belt hosts more than 500 Sb deposits accounting for 87% of the proven reserves in China and 55% of the world ( Figure 1 B; Wu, 1993 ; Fu et al., 2019b ) and constitutes an important part of the circum-Pacific Sb metallogenic domain ( Wu, 1993 ; Jin and Dai, 2007 ; Xiao, 2014 ). Antimony deposits in this belt are hosted in Proterozoic to Permian sedimentary rocks and structurally controlled by NE-trending folds and faults.…”

“…Despite of much attention received (e.g. Xiao, 2014;Fu et al, 2019aFu et al, , 2019b, the In the southwestern part of the South China Sb metallogenic belt, the Dushan Sb ore district hosts >30 Sb deposits ($287,000t Sb), including the Weizhai, Banpo, Banian, and Jiabai deposits (Figure 1C). These deposits are controlled by folds and faults, including (1) the NE-trending Dushan anticline formed in the Caledonian; (2) the NE-trending Dushan normal fault (29 km in length, 3-10m in width, and dipping SE with an angle of 50-80 ); (3) the NNE-trending Lantu normal fault (35km in length, 1-5m in width, and dipping NW with an angle of >70 ), and (4) numerous secondary folds and normal faults (Figures 1B and S1;e.g.…”
