南岭成矿带燕山成矿阶段矿床成矿系列研究进展和存在问题

With the progress of the study on metallogenic series of ore deposits in Yanshan metallogenic stage and Nanling metallogenic problems

南岭成矿带以与多时代花岗岩有关的钨锡稀有金属成矿为特色,是我国19个重点成矿区带中5个重点矿产勘察地区之一。根据其空间和成矿特点分为以钨矿床的密集产出为特征的南岭东段;钨、锡并重,并且锡的矿化已明显增强的南岭中段;以大规模的锡成矿作用为特征的南岭西段。南岭成矿带燕山期主要金属矿床分为4个成矿系列。南岭成矿带燕山期成矿作用可划分为,燕山早期的170~160 Ma、160~150 Ma和150~145 Ma,燕山晚期的~135 Ma和~100 Ma。

Nanling metallogenic belt in tungsten tin rare metal mineralization is related to many times of granite features, is China's 19 main metallogenic belt in the 5 key area of mineral exploration. According to the spatial and metallogenic characteristics of tungsten deposits are divided into the intensive output characteristics of Eastern Nanling; tungsten and tin and tin mineralization have both increased with tin mineralization in central Nanling region; large scale characteristics of Western nanling. The major metallic ore deposits in Nanling metallogenic belt of Yanshan period is divided into 4 metallogenic series. Yanshan can be divided into stages of mineralization in Nanling metallogenic belt, Yanshan early 170 ~ 160 Ma and 160 ~ 150 Ma and 150 ~ 145 Ma, the late Yanshan ~ 135 Ma and ~ 100 Ma.
