江西南部全南县火山岩产状及时代的讨论

A Disscussion on the Occurrence and Age of Volcanic Rocks in Quannan County,Southern Jiangxi Province

根据野外考察和有关的研究报告,作者认为全南县的火山岩是火山喷发碎屑岩类。中寨—南迳一带的火山岩的时代,根据地层分布和植物化石与粤东对比,建议划归早侏罗世。

Based on field observations and relevant research reports, the author presents in this paper his own viewpoint that the volcanic rocks of Quannan County are pyroclastic rocks. According to the stratigraphic distribution and phytolite and correlation with eastern Guangdong, the author suggests that the volcanic rocks of the Zhongzhai—Nanjing area should belong to the Early Jurassic.
