| 中文摘要: |
| 把吴川—四会断裂带北段,划分了四条金矿找矿成矿带,即新洲—石坎—江屯成矿带;龙潭—塔岗山—河台成矿带;桃源—北市成矿带;鱼坝—石狗成矿带.研究了控制成矿的时控条件认为,金矿主要形成于燕山晚期.矿体受区域性NE—NNE断裂构造带(新华夏系构造体系)活动控制.成矿富集因素是“矿源层”中不同构造带复合地段,构造古应力值增高的构造应力集中区以及深大断裂和岩浆作用深源物质加入的地段,这些地段以利于形成“矿源层”中的有利部位. |

| Four gold metallogenic belts are predicted in the north part of Wuchuan-Sihui fracture zone on the basis of recent years' works.They are Xinzhou-Shikan-Jiangtun belt,Longtan-TagangShan-Hetai belt,Taoyuan-Beishi belt and Yuba-Shigou belt.Gold ore is mainly formed in Late Yanshanian Period.Ore bodies is controled by regional NE-NNE fracture zones.Superposition of different structures in ore-source bed,stress concentration and activity of deep fracture and magma are factors for gold concentration.Sectors with the factors in ore-source bed are potential targets for prospecting. |
