黑龙江国土资源

青山洞矿区属湖南省洪江市雪峰镇管辖，位于洪江市北东，以交代石英岩型金矿石为主。本文以青山洞矿区金矿详查工程中的地质特征与矿体分布为研究对象，揭示详查区内地层、岩性、构造特征，主要矿体形态和矿石质量，并估算分析矿体的资源量。结果表明，青山洞金矿区严格受北西向构造破碎带控制，属破碎蚀变岩型金矿床。矿床规模属小型金矿床，共圈定17个工业矿体，探获(332)+(332)_低+(333)+(333)_低金矿石量691803t,推断金金属资源量2326kg。本文对青山洞矿区金矿的地质特征与矿体分布规律研究为矿山建设提供地质技术依据和实践指导借鉴。

Qingshan Cave is under the jurisdiction of Xuefeng Town, Hongjiang City, Hunan Province, which is located the northeast of Hongjiang City with mainly metasomatic quartzite type gold ore.This paper takes the geological characteristics and ore body distribution of the gold mine in Qhan Cave mining area as the research object in the detailed survey project to further reveals the geological layer, rock type, tectonic characteristics, the main ore body morphology and ore quality the survey area, and estimates and analyzes the resource amount of the ore body.The results show that the Qingshan Cave gold mine area is strictly controlled by the northwest-ductile-brittle shear zone, belonging to the fracture-altered rock type gold deposit.The scale of the deposit is a small gold deposit, and a total of 17 industrial ore bodies have been delineated, with the(332)+(332)_low+(333)+(333)_low ore amount of 691803t, and inferred gold metal resources of 2326kg.This study provides geological technical support and practical guidance for mine construction by exploring the geological characteristics and ore body distribution law of the gold mine in the Qingshan Cave mining area.
