回曲构造的控矿作用在红透山地区和辽宁东部的老变质岩系中有许多层控型矿床、矿点,矿种近十个。大多数是热液矿床。几十年来,已为前人肯定,我们认为是混合热液矿床。这些矿床、矿点,近矿围岩矿化蚀变现象普遍存在。矿体的形态是复杂的,粗眼看来是沿层产出的,仔细观测则切层、穿层、跨层、串层现象随处可见;有的呈矿柱产出,有的呈脉状、囊状产出。交代矿化作用是这些矿床、矿点的主要成矿方式;矿化过程是多阶段的;没有蚀变—矿化分带现象。矿化主岩是具一定化学性质、一定结构构造的变质岩,在混合岩化发育地区还有混合岩化产生的蟹斑状伟晶岩以及石英脉。矿体有在含矿层、矿沅层、含矿建造中的,为数很少。大多数矿体围岩的成矿物质含量很低,有许多低于其克拉克值,与矿体主岩同一层岩层的成矿物质含量,大多数也很低,有许多也低于其克拉克值。矿化没有固定层位,一个矿床常有几个矿体、矿化地
Orecline structure of the ore-controlling role In the Hongtoushan area and eastern Liaoning, the old metamorphic rock has many stratabound deposits, mineral deposits and mineral species nearly ten. Most are hydrothermal deposits. For decades, it has been affirmed by our predecessors that we think it is a mixed hydrothermal deposit. The mineralization and alteration of these ore deposits, ore deposits and nearby ore are ubiquitous. Ore body morphology is complex, coarse-grained appears to be output along the layer, careful observation of the cut, stratification, cross-stratification, stratification phenomenon can be seen everywhere; some ore pillar output, and some veins, Cystic output. The account of mineralization is the main metallogenic mode of these deposits and ore deposits; the mineralization process is multi-stage; there is no alteration-mineralization and zoning phenomenon. The mineralized host rock is a metamorphic rock with a certain chemical property and a certain structural structure. In the area where the mixed rock is developed, there are also crabbed pegmatites and quartz veins produced by mixed rockification. There are a few ore bodies in ore-bearing layer, ore-Yuan layer, ore-bearing construction. Most ore bodies are of low ore-forming material content, with many below their Clarke values and most of the metallogenic material content of the same strata as the host rocks, and most are also low, many also below their Clarke values . Mineralization is not a fixed horizon, a deposit often several ore bodies, mineralized
