摘要 小甸子区位于开原~草市多金属成矿带的西段,西侧为郯庐深大断裂,开原~营口段,南侧为北西西向沙河断裂。由于本区特殊的大地构造环境,所以本区经历了多个时期的大地构造运动及岩浆活动。不同时期的构造运动和岩浆活动所构成的成矿环境的差异性,影响着成矿元素的运移和富集。最终导致在不同成矿期下形成不同类型的金属矿床。 Xiaodianzi area is located in the western part of the Kaiyuan^Caoshi polymetallic metallogenic belt, with Tanlu deep fault in the west, Kaiyuan^Yingkou fault in the South and Shahe fault in the northwest-west direction in the south. Because of the special geotectonic environment in this area, it has undergone many periods of tectonic movement and magmatic activity. The difference of metallogenic environment formed by tectonic movement and magmatic activity in different periods affects the migration and enrichment of metallogenic elements. Ultimately lead to the formation of different types of metal deposits in different metallogenic stages.
