| 中文摘要: |
| 中国金矿床的时空分布不均一，金矿主要产于稳定陆块边缘或稳定陆块内的活动带，形成了金的矿集区，成矿时代主要以中生代为主，其次为晚古生代及新生代，而早古生代和前寒武纪金矿床则处于相对次要地.从地质构造演化的角度探讨金矿形成的大地构造背景,认为金矿的形成及分布受控于壳幔相互作用及岩石圈不连续。 |
| 英文摘要: |
| The gold deposits in China are distributed in a highly non-uniform manner. The most gold ores are found along the orogenic belts around stable platforms or mobile belts within stable continental blocks, forming gold mineralization belts. These gold deposits were generated mainly in the Mesozoic, secondly in the late Paleozoic and Cenozoic, few in early Paleozoic and Pre-Cambrian times. From geological evolution, this paper discusses the tectonic setting for mineralization of the gold deposits. It suggests that crust-mantle interaction and the discontinuity within the lithosphere are two primary factors that determined the generation and distribution of gold deposits in China. |
