西林河脆－韧性剪切带是区域上富尔河－古洞河岩石圈深断裂带的重要组成部分，总体走向３３０°，由东部（Ｆ１，Ｆ２，Ｆ３）、中部（Ｆ４，Ｆ５）和西部（Ｆ６）３条脆－韧性剪切断层带组成。东部带以脆性变形为主，延长约４ｋｍ；中部带除脆性变形外兼有塑性变形，延长约５ｋｍ；西部带以塑性变形为主，总延长５．５ｋｍ。构造岩比较发育，分为脆性变形构造岩系列和塑性变形构造岩系列。构造岩的变形和退变作用同时进行。西林河脆－韧性剪切带反映了西林河金矿的成矿时代为燕山期，是金成矿的导矿和容矿构造。本着就矿找矿的原则，根据成矿地质条件，在已有的６个矿体的延伸方向进行追索找矿；根据边缘成矿作用观点，可在矿区内太古宙灰色片麻岩与元古宙浅变质岩的接触带进行找矿。确立了６条找矿标志。
The Xilin River brittle-ductile shear zone is an important part of the deep faulted lithosphere in the Upper Furu River and Kwu Tung River, with an overall strike of 330 °. It consists of eastern (F1, F2, F3), central (F4, F5) and western (F6) Three brittle-ductile shear fault zones. The eastern zone is dominated by brittle deformation, extending for about 4km. The middle zone is both plastic and brittle but extended by about 5km. The western zone is dominated by plastic deformation with a total extension of 5.5km. Tectonic rocks are relatively developed, divided into brittle deformation tectonic series and plastic deformation tectonic series. Deformation and degeneration of tectonic rocks occur simultaneously. The Xilin River crisp-ductile shear zone reflects the fact that the Xilinghe gold deposit was hosted during the Yanshanian period and is a gold-bearing mineralization and ore-hosting structure. According to the principle of ore prospecting, according to the geological conditions of mineralization, the prospecting is conducted in the extending direction of the existing 6 ore bodies. According to the edge mineralization, the archaeozoic gray gneiss and Proterozoic metamorphic rock contact zone for prospecting. Established six prospecting signs.
