粤东宝山嶂地区锡多金属矿成矿地质条件及成矿规律分析

Analysis of geological conditions and metallogenic law of tin polymetallic ore deposit in zhangjiaoshan region of guangdong province

粤东宝山嶂地区锡多金属矿处于河源(龙川段)深断裂与莲花山深断裂(五华段)所夹持地带,属华夏钨锡铅锌铜铁成矿亚带,北东向紫金大断裂贯穿全区,区内燕山期岩浆及构造活动强烈,成矿条件优越。本文分析了区内地层及岩性组合、构造、岩浆岩及地球化学等成矿地质条件,通过宝山嶂地区矿产分布规律、时空分布规律、成矿时间及矿质来源等几个方面概括了该区锡多金属矿的成矿规律,并提出了该地区的找矿方向。

Tin polymetallic deposits in the east guangdong baoshan ailian heyuan（longchuan） deep fracture and lotus deep fracture（five degrees） the clamping zone, belongs to the Chinese tungsten tin lead and zinc iron copper metallogenic belt, north east to zijin faults throughout the district, district strong yanshanian magmatic and tectonic activity, metallogenic condition is superior. This paper analyzes the area stratigraphic and lithologic combination, structure, magmatic rocks and geochemical metallogenic geological conditions, such as by baoshan ailian regional mineral distribution, space-time distribution, ore-forming time and sums up the several aspects, such as ore source tin polymetallic metallogenic regularities in the area, and puts forward the prospecting direction in the region.
