| 摘 要： | 河南嵩县南部熊耳群古火山构造保存完整，喷发旋回清晰，火山岩相及爆发相主要岩石种类齐全。其主要喷发类型为裂隙式喷发，次为中心式喷发，主要受区域基底断裂控制，且沿区域切壳深大断裂带呈串珠状分布。表明基底断裂一火山喷发带一区域断裂带是一个连续发展的过程。区内金及部分有色金属矿产与熊耳群古火山活动密切关联，古火山口爆发角砾岩产出地段是寻找该类型金矿的最佳地段，受古火山构造控制的古火山口及其周边的中性、酸性次火山岩脉（墙），是寻找钼、金、铅锌多金属矿产的有利部位。

| Abstract: | Fossil volcanic structure of Xiong＇er group in southern Songxian, Henan province, is preserved completely with clear eruption cycle, and composing of integrity rock series of volcanic facies and eruption facies. The mainly eruption styles are fissure eruption and central eruption, which is controlled by regional basement rift, what makes the volcanic structures present as pinch - and - swell form along regional ultracrustal fault belt. It＇s a developmental sequence from basement rift through volcanic eruption belt to regional faulted zone. Golden and some colored metal deposits are related to volcanic activity of Xiong＇er group, especially the explosion breccia of fossil volcanic cater which maybe the most potential prospecting target; and for the molybdenum, copper, and lead -zinc deposits, the fossil volcanic cater with intermediate -felsic sub - volcanic dykes are the potential prospecting target. |
