| 摘 要： | 粤东地区燕山期火山岩盆地沿NE向呈带状展布,其中分布有众多的铜-铅-锌多金属矿点,具有良好的成矿地质条件和找矿潜力。近年该区的地质勘查工作取得了突破,发现了尖笔岽、四望坪矿床。矿床为隐伏的脉状充填型热液型矿床。隐伏矿床地表常表现为矿化蚀变带或褐铁矿化的小破碎带,土壤次生晕异常形态与隐伏矿体走向一致,异常元素组合和成矿元素一致,是本区隐伏的脉状矿床的有效的找矿标志。

| Abstract: | There are many copper-lead-zinc ore spots in the volcanic basin of east Guangdong.There is a great potential in ore-finding in the area.The Jianbidong and Siwanping deposit have already been found in it.They are concealed hydrothermal deposit.The deposit is characterized by a mineralized alteration belt and small fracture zone of limonite mineralization in the surface.The orientation of soil geochemical anomaly is coincided with that of concealed orebodies and the anomaly element combination is consistent with the ore elements,therefore the anomaly is an effective ore prospecting indicator for concealed vein type deposit in the area. |
