地壳各部分的矿产是受着成矿条件与分布规律的双重控制的。前者即物质来源。围岩条件和元素的地球化学特性,后者主要是成矿时的活动构造体系及其复合关系,两者相互影响、相互制约,但它们又统一于构造运动过程之中。换言之,建造与改造在构造体系的形成发展过程中是相辅而行的,成岩成矿作用是在构造条件控制下,地壳中物质运移、集散等再分配的过程与结果。因而常见岩带、矿带、物化探异常带总是与一定的构造带高度吻合,组成构造岩相成矿带,长江中下游铁铜成矿带可视为一个较好的实
The mineral resources of various parts of the crust are subject to the dual control of metallogenic conditions and distribution. The former is the material source. Rock conditions and geochemical characteristics of the elements. The latter is mainly the active tectonic system and its complex relationship during mineralization. The two interact and restrict each other, but they are unified in the process of tectonic movement. In other words, construction and reconstruction are complementary to the formation and development of the tectonic system. Diagenesis and mineralization are the process and result of redistribution of materials in the crust under the control of structural conditions. Therefore, common rock belt, ore belt, geochemical anomaly belt are always highly consistent with a certain tectonic belt, forming tectonic facies metallogenic belt, and the iron-copper mineralization belt in the middle and lower reaches of the Yangtze River can be regarded as a better
