云南省广南县堂上金矿床为“滇黔桂”众多大型金矿床之一,其矿床特征以矿体数量多(已知矿体89条),矿化空间范围广(自中三叠统版纳组三个岩性段到上二叠统那梭-长兴组、峨眉山玄武岩、大厂层均赋存矿体, T2b3→T2b2→T2b1→P2n+c→P2β→P2dc),矿体严格受断裂构造控制,显示矿床与众不同的特征。矿区已探获普查金资源量18 t,预测金远景资源量40 t。
雲南省廣南縣堂上金礦床為“滇黔桂”衆多大型金礦床之一,其礦床特徵以礦體數量多(已知礦體89條),礦化空間範圍廣(自中三疊統版納組三箇巖性段到上二疊統那梭-長興組、峨眉山玄武巖、大廠層均賦存礦體, T2b3→T2b2→T2b1→P2n+c→P2β→P2dc),礦體嚴格受斷裂構造控製,顯示礦床與衆不同的特徵。礦區已探穫普查金資源量18 t,預測金遠景資源量40 t。

As one of the numerous large-size gold deposits in “Yunnan-Guizhou-Guangxi”region, the Tangshang Au deposit in Guangnan County of Yunnan Province possesses a large number of ore bodies ( with 89 known ore bodies) and wide mineralization space (ore bodies are hosted by a wide range of strata: from three lithologic members of Middle Triassic Banna Formation to Upper Permian Nasuo-Changxing Formation, Emeishan basalts, and Dachang layer, T2b3→T2b2→T2b1→P2n+c→P2β→P2dc), and its ore bodies are strictly controlled by faulted structure, thus displaying its unique characteristics. The proven reconnaissance gold resource quantity has reached 18t, and the prognostic gold prospective resource quantity is 40 t.
