| 摘 要： | 明溪盖洋地区广泛发育的震旦纪火山岩，均已遭受区域变质，前人多数是从变质岩角度对其作研究，笔者是从火山岩及火山作用角度，在调研变质火山岩岩石宏观与微观特征的同时，着重调查古火山构造，研究不同火山产物空间分布特征，寻找残存的古火山构造形迹，并结合遥感资料信息。初步恢复古火山中心，为研究这一时期火山活动特点乃至南平-宁化构造-岩浆带的演化及古构造环境提供了新的资料。

| Abstract: | The Sinian volcanic rocks,which are widely exposed to the Gaiyang area of Mingxi County,have metamorphosed.According to the macroscopical and microcosmic characteristics of the volcanic rocks and volcanism,to the distribution characters of different volcanic products and paleovolcanic structures and to the survivors of paleovolcanic structures and the remote sensing data,the authors made a preliminary restoration of the paleovolcanic center.It is helpful to study the characteristics of the volcanic activities in Sinian Period,the evolution of the Nanping Ninghua Tectonic Magmatic Belt and the palaeotectonic setting in the surveyed area |
