摘　　要：为对金矿资源的勘查、开发与潜力评价提供理论支撑,深入剖析腾龙岭金矿的地质特征,探索矿床成因机制。对金矿所在区域的地层、构造、岩浆岩等地质背景展开系统研究,详细分析金矿体的形态、规模、产状、矿石类型、矿物组成以及围岩蚀变特征等。运用地质填图、岩石薄片鉴定、地球化学分析等多种手段,查明该金矿赋存于晚石炭统石钱滩组地层与深大断裂派生的次级构造中,矿体多呈脉状、透镜状;矿石类型主要有构造蚀变岩型,围岩蚀变发育褐铁矿化、黄铁矿化、硅化等;金矿的形成与构造侵入的闪长玢岩脉密切相关,矿床成因类型为构造蚀变岩型。本研究成果不仅深化了对该金矿矿床成因的认识,更为区域内金矿资源的进一步勘查与开发指明了方向,对相似地质背景下的金矿找矿工作具有指导意义。It provides theoretical support for the exploration,development and potential evaluation of gold resources,the geological characteristics of Tenglongling Gold Deposit are deeply analyzed,and the genetic mechanism of the depositis explored.The geological background of strata,structure and magmatic rock in the area where the gold deposit is located is systematically studied,and the form,scale,occurrence,ore type,mineral composition and alteration characteristics of the surrounding rock are analyzed in detail.By geological mapping,thin section identification and geochemical analysis,it is found that the gold deposit exists in the secondary structure derived from the Late Carboniferous Shiqiantan Formation and deep fault,and the ore bodies are mostly vein-like and lenticular.The main ore types are structural altered rock type,and the alteration of surrounding rock develops limonite,pyrite,silicification,etc.The formation of gold deposit is closely related to diorite porphyrite veins with structural intrusion,and the genetic type of the deposit is tectonically altered rock type.The research results not only deepen the understanding of the genesis of the gold deposit,but also point out the direction of further exploration and development of gold resources in the region,and have certain guiding significance for gold prospecting under similar geological background.
