前言 自五十年代始,在我国华南褶皱系的北缘,相继发现多处成矿时代相近的细碧角斑岩型铜矿床。其中以浙江绍兴西裘铜矿和江西弋阳铁砂街铜矿发现最早,工作程度也较高(图1)。该两矿床的发现,对于嗣后在相似的地质构造条件下寻找同类矿床,起了重要的作用。 Preface Since the fifties, in the northern margin of the South China fold system, many small Pithorite porphyry copper deposits have been discovered in succession. Among them, the earliest and the highest degree of work was found in the West Qiu copper mine in Shaoxing, Zhejiang and Tiexi iron sand street in Jiangxi Province (Figure 1). The discovery of these two deposits played an important role in finding similar deposits later under similar geological conditions.
