摘要
扬州仪征捺山上新世盾形火山机构是一套"爆发相—溢流相—次火山相"喷发旋回,伴有多个寄生火山口,其完整程度为江苏唯一,国内罕见。文章系统介绍捺山上新世盾形火山机构,详细论述该火山机构的地质特征及成因。这是对该地质遗迹进行的首创性工作,对进一步的地质科研、科普教育及生态旅游具有重要意义。
The Pliocene shield volcanic mechanism in Nashan, Yizheng of Yangzhou displays an eruptive recycle of explosive-effusive-subvolcanic facies, accompanied with multiple parasitic craters. It is the only one with complete volcanic relic in Jiangsu province and rare in China. This paper systematically describes the Pliocene shield volcanic mechanism in Nashan and analyses the origin and geological features in details. This is the first research conducted in the area and therefore has great significance to the protec- tion and development of the geological relic because it is the most important geological resources for geo- logical scientific research, science education, and ecological tourism.
