福建晚中生代火山地层研究新进展

New researching development of Late Mesozoic volcano formation in Fujian Province

对晚中生代火山岩石地层进行区域对比研究,认为武夷、沿海地层小区及浙东南地区晚中生代火山岩石地层基本可以对比。沿海、武夷地层小区的南园组及石帽山群,岩石组合特征、生物群面貌及时代基本相同,并分别可与浙东南地区的高坞组及永康群对比,可作为区域火山岩石地层对比的标志层,解决了福建东、西部及闽浙两省中生代火山岩石地层对比的关键问题,为最终在中国东南沿海火山岩带建立统一的晚中生代火山岩石地层系统具有重要推动作用。

Compared the areas of Late Mesozoic volcano formation, it is considered that Late Mesozoic volcano formation can be compared between in Wuyi, coastal stratigraphic areas and southeastern Zhejiang. The rock combination featurees of Nanyuan formation and Shimaoshan group , the biota features and the age are basically the same in Wuyi and coastal stratigraphic areas. Through compareing with Gaowu formation and Yongkang group in southeastern Zhejiang, it can be the marker bed of regional voicano rock formation comparison. The key questions of Mesozoic volcano rock formation camparison of Fujian and Zhejiang are solved, which provides important promotion for building unity of Late Mesozoic volcano rock stratum system in the southeast coast of China.
