摘要
黔东南是一个线性、环形构造十分发育的地区,内生金属矿产种类多、分布广。环形构造有300多个,大小不等,形状各异。该区存在两个环形构造带,即都江—梵净山、从江—辰溪环形构造带,两个环形构造带的位置与北北东向线性构造带和重力低异常带相一致,而内生金属矿产与环形构造的关系极为密切。
Southern Guizhou is an area where the linear and ring structures are well developed and there are more kinds of hydrotherma! metal ores which are widely distributed. There are three hundred ring structures, with the sizes unequal and the forms different, The diameter of the largest ring structure is up to 110km and that of the smallest one is about 1 km. The forms of the ring structures are round, ellipse or irregular. There are two ring structure belts, that is, the Dujiang-Fanjing-shan ring structure belt and the Congjiang -Chenxi ring structure belt. The positions of the two belts are identical with the NNE linear structure belt and the abnormal belt with low gravity. The relationship between the hydrothermal metal ores and the ring structures is very close.
