镇安金龙山-丘岭金矿田地质特征、成矿预测与找矿前景

通过容、含矿地层及构造等控矿因素分析，表明矿田范围内找矿潜力很大。建议在矿田东西两侧有限范围及矿田剪切带北部地表找矿。同时，找矿的重点应放在对主矿带的沉吟部预测研究上。

Geologic characteristics, metallogenic prognosis and ore-finding foreground of Jinlongshan-Qiuling gold field in Zhen'an county

The potentiality of the ore finding in the scope of the Jinlongshan Qiuling Micro Disseminated (Carlin type) gold field has been discussed in the paper based on the ore controlling factors analysis The gold deposits present the stratabound feature of sedimentary inferior reformation type The distribution of the gold deposits are controlled by the restricted platform basin lithosfacies which are composed of terrigenous fine grained clastic rocks and carbonate rocks of the Late Devonian and Early Carboniferous The former is frequently alternative with the latter This restricted platform basin lithosface has the dual formation, that is not only the host strate of the ore bodies,but the ore bearing strate of the gold deposite Structure is the main factor of mineralising in this area and it is the important sign of ore finding too The places on the fault crossing with the shearing often form the industry ore bodies The folded shearing structure deformation belt of ore controlling extends to the deep with the steeper dip form,and so it means that there are better conditions of ore finding in deeper of the area It is suggested that the surface ore finding should be developed on a limit scope both in the east and west of gold field folded shear zone, meanwhile the important part of ore finding should be further studied in deep metallogenic prognosis of main ore zone
