| 摘 要： | 粤北地区钨锡矿床成因类型有三大类,工业类型主要有八种.石英脉型钨锡矿是目前最主要的工业类型,此类矿床不仅可在浅变质碎屑岩、花岗岩中以“五层楼”式产出,而且也可在碳酸盐岩中以“五层楼”式产出.钨锡成矿时期在中侏罗世晚期到早白垩世,晚侏罗世是矿床形成集中期.钨锡矿床沿岩浆岩带分布,均与岩浆作用有关.钨锡矿田沿岩浆岩带分布于不同方向区域性断裂交汇区,在浅变质碎屑岩区以钨矿为中心可形成钨-钨锡-锡铅锌-铅锌-金的矿化分带,在碳酸盐岩区可形成钨锡-铅锌-锑金矿化分带,为钨锡铅锌银金锑成矿系列.

| Abstract: | The tungsten-tin（W-Sn） deposits of northern Guangdong province can be divided into three genetic types or eight industrial types.Quartz vein-type W-Sn deposits is the most important industrial type,which can be occurred in ＂Five Floors＂ style in shallow metamorphic fragmental rocks,or granitic rocks,or carbonate.The formation ages of W-Sn deposits are from early Mid-Jurassic to Early Cretaceous,while Late Jurassic is the most concentration formation age.Most W-Sn deposits are distributing along magmatic rocks belt,and have got relationship with the surrounding magmatic rocks.The W-Sn ore districts are favored the place where regional faults meet.In the shallow metamorphic fragmental rocks area,centre to the tungsten deposits lays the W,W-Sn,Sn-Pb-Zn,Pb-Zn to Au deposits to periphery,but in the carbonate rocks area lays the W-Sn,Pb-Zn,and Sb-Au deposits belt,which belong to W-Sn-Pb-Zn-Ag-Au-Sb metallogenic series. |
