摘　　要：0.INTRODUCTION.The Jiuwandashan Sn-polymetallic ore cluster,located in the western part of the Jiangnan Orogen and the Nanling Metallogenic Belt,is one of the most significant Precambrian tin ore concentration areas in South China(Figure 1a;Mao et al.,1987).Recently,this region has garnered considerable research attention due to its intense mafic-felsic magmatic activity and large-scale Sn-polymetallic mineralization(Li et al.,2020;Chen J F et al.,2019;Huang and Wang,2019;Zhang et al.,2019;Chen L et al.,2018;Xiang et al.,2018;Su et al.,2014).A series of medium-to large-scale Sn-polymetallic deposits,including Jiumao,Liuxiu,Yidong,Honggangshan,and Shaping(Figure 1b),have been identified within this region,with proven tin reserves of approximately 200000 t.High-precision dating methods have yielded cassiterite U-Pb ages of ca.830 Ma,pointing to a Neoproterozoic Sn-polymetallic mineralization event in South China(Zhang et al.,2019;Xiang et al.,2018).
