Based on restudying the sedimentary sequence and evolution of Banxi Group in Xiushan-Fanjingshan area,the authors performed the crystal tuff SHRIMP zircon U-Pb dating for Hongzixi Formation of Banxi Group in Xiushan area.
关于板溪群的时代归属及其地层划分对比,一直以来存在较大争议,为此作者在重新研究了秀山—梵净山地区板溪群的沉积序列及其演化的基础上,首次对秀山凉桥地区的板溪群红子溪组顶部的晶屑凝灰岩进行了SHRIMP锆石U-Pb测年,研究显示板溪群早期的盆地扩张阶段结束于790Ma左右,随后盆地转入快速充填和差异升降阶段。

Based on a comprehensive study on faciology, petrology and petrogeochemistry, the ignimbrites widely distributed in Mesozoic volcanic basin in South Jiangxi are divisible into three types namely the clastic flow, the surge flow, and the subvolcanic types, of which the genetic mechanism has been discussed in this paper.
本文通过对赣南中生代火山盆地内广泛分布的熔结凝灰岩类的岩相学、岩石学、岩石 地球化学特征的综合研究，将熔结凝灰岩类划分为碎屑流型、涌流型、次火山型等３种类型，并对其 成因机理进行了讨论。

In pyromerides and ignimbrites,micropores from devitrification are the second largest pore type after the vesicle,accounting for 20%and 30%of the total of all pore types in pyromerides and ignimbrites respectively.
球粒流纹岩、熔结凝灰岩中脱玻化孔是仅次于气孔的第二大孔隙类型,球粒流纹岩和熔结凝灰岩中脱玻化孔分别占相应岩石中所有类型孔隙的20%,30%左右。
