摘　　要：河南嵩县黄庄-汝州高水泉一带熊耳群火山岩分布区属构造变动强烈的中深剥蚀区。依据岩石岩相标志、断裂构造形迹、火山岩的产状以及地貌标志等,首次识别出活动于许山期、鸡蛋坪期及马家河期的五个古火山口和一个古裂隙喷发带。熊耳群火山活动早期为NEE向裂隙式喷溢,中期演化为中心式喷发、伴有裂隙式喷发,晚期为中心式喷发。区域火山活动贯穿整个熊耳期,时间自NE向SW由早到晚。古火山口及受其控制的次火山岩与区域矿产关系密切。The volcanic region of Xiong＇er Group along Huangzhuang of Songxian - Gaoshuiquan of Ruzhou belongs to the medium -deep denudation region with the intense tectonic event（disturbance）. On the basis of the rock - lithofacies marks, the faulted structural feature, the occurrence of the volcanic rock region and the gcomorphologic signs of palacovolcanic crater etc. , five palacovolcanic craters and one palaeo - fissure eruption zone of the Xushan, Jidanping and Majiahe age of the Middle Proterozoic era have been firstly identified in the study area. The Xong＇er Group volcanic activity was mainly the fracture outpouring in the direction of NWW in the early time, and the eruption of central type following the fissure eruption in the middle time, and then is the eruption of central type in the late time. The regional volcanic activity showed that NE - trending regions occurred early and SW trending - regions later. The palacovolcanic craters and the subvolcanics controlled by closed with the regional mineral resources.
