本文主要以内生脉状矿床为例,简要地论述了矿田构造的基本特征和发展规律。 (一) 按成矿与基底构造的关系,我们将矿田分为同生类和叠生类。前者是指与褶皱带(活动区)同一时期形成的矿田,构造型式以褶皱为主,区域构造的形成发展和成矿过程基本上是连贯和衔接的。叠生类矿田较前类复杂而多样,它形成于稳定的地块或固化的褶皱带之后,构造型式主要为断裂。成矿构造与成矿作用叠加在老的基底地质体之上,成矿与基底构造形成的时间间距可达几个代和纪,这一类型经历的时间很长,受多期构造运动的
In this paper, we mainly take the endogenous vein-like deposits as an example to briefly discuss the basic characteristics and development rules of the ore field structure. (A) According to the relationship between mineralization and the basement structure, we classify the orefields into symbiotic and conglomerates. The former refers to the ore field formed at the same time as the fold zone (active zone), and the structural type is dominated by fold. The formation and development of regional tectonics and ore-forming process are basically coherent and connected. The strata-type ore field is more complex and diverse than the previous one. It is formed after a stable block or a fixed fold belt, and the structural type is mainly fault. The metallogenic structure and mineralization superimposed on the old basement geological body, the time interval between metallogenic and basement structure can reach several generations and records, this type has experienced a long time, by the multi-period tectonic movement
