黑龙江省尚志市亮河镇一带成矿规律
|
摘要
尚志市亮河镇地区地处黑龙江省南部,是我国张广才岭北侧比较重要的金成矿带之一。本文介绍了该区的地层、构造、岩浆岩,特别是燕山早期的岩浆活动与研究区内斑岩型钨钼矿床成矿关系密切。结合研究区的大地构造背景,推断本矿床的形成应该与燕山期太平洋板块的俯冲有关,属于燕山期环太平洋成矿带对古亚洲洋成矿带叠加时期的成矿活动之一。根据上述条件指出找矿远景区——大崴子、华山林场和东南岔地区。
Lianghe Town of Shangzhi City is located in the south of Heilongjiang Province, is one of the most important gold metallogenic belts in the north of Zhangguangcailing Mountains in China. In this paper, the strata, structure and magmatic rocks in this area are introduced, especially the early Yanshanian magmatic activity, which is closely related to the mineralization of porphyry W-Mo deposits in the study area. Based on the geotectonic background of the study area, it is inferred that the formation of the deposit should be related to the subduction of the Yanshanian Pacific plate, which is one of the metallogenic activities of the Yanshanian circum-Pacific metallogenic belt during the superimposition of the Paleo-Asian oceanic metallogenic belt. According to the above conditions, the writers pointed out that the prospecting areas are Dawaizi, Huashan Forest Farm and Dongnancha area.
