| 摘 要： | 甘肃北山地区是古亚洲成矿域重要的组成部分,包含了两个（即准噶尔成矿省、塔里木成矿省）金、铜、铅、锌、钨、钼、铷、铁等重要成矿省,目前已发现重要矿产地289余处,成矿时段以华力西期为主。本文通过对甘肃北山地区成矿地质背景和成矿在时空上的联系性、矿产预测类型、成矿作用演化的综合研究,简要介绍了Ⅳ级成矿亚带地质矿产特征;重点讨论了区域成矿控制因素;并归纳总结了矿产预测类型,概述了区域成矿的时空演化规律。以期为矿产勘查和地质大调查工作部署提供了新的思路和依据。

| Abstract: | Beishan area in Gansu province is an important part of the paleo-Asian metallogenic domain. It contains two important metallogenic province（namely Junggar metallogenic province and Tarim metallogenic province） producing gold, copper, lead, zinc, tungsten, molybdenum, rubidium and iron. More than 289 important ore fields have been found in this area, and they are mainly formed in the Variscan. We adapt the integrated study on metallogenic background, and the temporal and spatial connection, the mineral prediction type,metallogenic evolution in Beishan area of Gansu to give a brief introduction on the feature of grade IV metallogenic belt of Geology and mineral resources, a discussion on the regional metallogenic control factors, and a summary on the mineral prediction type and the spatial and temporal evolution of regional mineralization. We hope it can provide new ideas and basis for the deployment for mineral exploration and geological survey. |
