福建省晚侏罗世—白垩纪陆相火山岩地层划分,对比研究

本文应用地层多重划分观点和方法，对福建省东、西部中生代陆相火山沉积岩系进行地层划分、对比，确立晚侏罗世─白垩纪岩石地层单位１９个，其中群级４个，组级１５个，并与年代地层单位进行对比，指出坂头组与小溪组属晚侏罗世一早白垩世，火山岩地层从内地（西北）向沿海（东南）略具穿时特点。

Classification and Correlation of Late Jurassic-Cretaceous Continental Volcanic Rock Strata in Fujian Province

This peper reports on the research results of late Jurassic-Cretuceous continental volcanic rock strata in Fujian Province. In this poper, the stratigraphic classification and correlation of Mesozoic continental volcanic sedimentary rocks in the eastern and western parts of Fujian Province have been made by using the theory and method of the multiple stratigraphic classification. Nineteen late Jurassic-Cretaceous stratigtaphic units have been established in the surveyed area, including 4 groups and 15 formations,Which had been compared to the stratigraphic-time unit. It points out that the Xiaoxi Formation belongs to latch Jurassic-early Cretaceous strata and that the diachronism from inland (Northwestern Fujian) tocoast (Southeastern Fujian) is characteristic of the volcanic rock strata in Fujian Province.
