休宁县里广山地区区域上位于扬子陆块江南地块障公山隆起(障公山复背斜)北缘,夹于祁门断裂构造带和障公山韧性剪切带之间。区内地质构造复杂,经历了多期次构造活动,成矿地质条件优越,化探异常突出,1:20万和1:5万水系沉积物测量均显示有较好的Au、Sb、As、Sn等元素的综合异常,区内已发现多处锑、金矿床或矿(化)点,具有较好的找矿前景。本文重点从化探异常及成矿地质条件分析来探讨该地区的找矿潜力。
休寧縣裏廣山地區區域上位于颺子陸塊江南地塊障公山隆起(障公山複揹斜)北緣,夾于祁門斷裂構造帶和障公山韌性剪切帶之間。區內地質構造複雜,經歷瞭多期次構造活動,成礦地質條件優越,化探異常突齣,1:20萬和1:5萬水繫沉積物測量均顯示有較好的Au、Sb、As、Sn等元素的綜閤異常,區內已髮現多處銻、金礦床或礦(化)點,具有較好的找礦前景。本文重點從化探異常及成礦地質條件分析來探討該地區的找礦潛力。

Liguangshan District of Xiuning County is located at northern limb of Zhanggongshan anticlinorium in Jiangnan Massif, Yangtze Block. It is also situated between Qimen fault belts and Zhanggongshan ductile shear zones. Having suffered multiple tectonic movements, this region owns complicated geological settings, favorable metallogenic conditions and prominent geochemical anomalies. The stream sediment surveys of 1:200000 and 1:50000 appear preferable comprehensive anomalies of Au, Sb, As, Sn etc. In terms of a large amount of Sb, Au or other metal mineralized points have been detected, the region is capable of better prospecting potential. This article is going to explore the potentiality of this area with analysis of geophysical and geochemical anomalies and geological conditions.
