摘要
团结构金矿是一个产于花岗斑岩中的大型岩金矿,由于所发现的金矿体绝大部分赋存在花岗斑岩中,因此长期以来,针对该区的找矿评价工作,均主要围绕花岗斑岩展开。本文通过对该矿区及其外围地区的矿石和岩石的稀土配分模式、硫同位素、包体测温等方面的系统分析与比较,发现该金矿床虽然在空间上与花岗斑岩关系密切,但在成因上却不相关。因此,本文对该矿床的控矿构造规律重新进行了系统分析和归纳总结,提出了火山次火山机构的内环带构造是区内金矿体最主要的控矿构造的新认识,进而指出了团结沟金矿田今后的找矿方向。
The Tuanjiegou gold deposit is a large-size rock gold ore deposit lying in granite-porphyry.As the main ore bodies of this ore deposit have been found in the granite-porphyry,the prospecting and evaluation work in this area has long been mainly carried out within the granite-porphyry.A synthetic analysis and comparative study of the distribution model of REE,the characteristics of sulfur isotope and the temperature of fluid inclusions of the ores and rocks in the ore district and its surrounding areas show that,although the gold deposit is closely related to the granite-porphyry in space,they have no genetic relationship.In this paper,the ore-controlling regularity of the ore deposit is analyzed and summarized systematically,and a new idea is put forward arguing that the structure of the inner circular belt of the volcanic and sub-volcanic edifice is the main ore-controlling structure element.In addition,some favorable ore-prospecting segments in the Tuanjiegou gold orefield are delineated.
