| 摘 要： | 西秦岭从中晚泥盆世开始,秦岭微板块由于勉略带的裂解扩张而进入独立演化,其构造演化、构造环境、沉积建造、岩浆活动和成矿作用等具有南北基本对应的准对称特征。本文通过对比分析,认为白龙江构造带是热液再造型铅锌矿的有利成矿带,而北部夏河—礼县成矿带南缘则是金的找矿远景区。

| Abstract: | From mid-upper Devonian on,in West Qinling area, Qinling microplate went into independent evolution by cracking and extension of Mianlue belt and it formed a para-symmetry characteristics from south to north.On tectonic evolution,tectionic environment,sedimentary formation,magmatic activity,ore-forming process and so on. Through correlation and analysis, we suggest that Bailongjiang tectonic belt is an advantageous metallogenic belt to hydrothermal re-formed Pb-Zn ore deposit,the northern however,at south side of Xiahe-Lixian metallogenic belt is a prospecting region for gold. |
