| 摘 要： | 长江中下游地区,是中国东部重要的地洼金属成矿带,其成矿受地洼构造和岩浆岩的控制,也受前地洼阶段多种建造与构造的深刻影响。在此成矿带中,控制矿田形成和分布的构造——地洼成矿区构造的基本特征是基底断裂与环形构造系的复合。可概括为两种地洼成矿区构造类型:1.优地洼中基底断裂与环形构造系复合的成矿区构造,2.地穹上基底断裂与环形构造系复合的成矿区构造。

BASIC CHARACTERISTICS OF STRUCTURES IN THE MIDDLE-LOWER YANGTZE VALLEY DIWA (GEODEPRESSION) METALLOGENIC PROVINCE |

| Abstract: | The Middle-Lower Yangtze River Reaches is a inportant diwa metallogenic zone. Its mineralization is controlled by diwa structures and magmas, and also affected deepiy by diverse pre-diwa formations and structures. In the zone, the charactiristic of the structures in diwa metallogenic province that control the formation and distribution of ore province is the compounding of basement fractures and ring structurl ststens, Synnaruktm the structures of diwa metallogenic province can be divided into two types: one is formed by compoundirg of basement fractures in eu-diwa and ring structural systems; and the other, by compounding of the basement fractures in geodome and rng stouctura systems. |
