  • 简介:从Dabie的南方盆的沙岩的由岩屑形成的模式(大别)orogenic带由于多重供应在早中间的侏罗记期间是复杂的。从降低中间的侏罗记的媒介粗糙的沙岩的由岩屑形成的作文,Huangshi(黄石),表演三主要起源:再循环的ororgen,暴烈的弧(弧orogen),和区别形式的作文的图和沙岩petrofacies的分析的Dickinson的底上的大陆人块。与稀少的出版paleocurrent数据,学习区域的大地构造的背景,和未出版的由岩屑形成的锆石年龄结合了数据,主要起源的位置如下被推断:在华东的沿海的orogenic带(圆块)作为再循环的orogen起源提供了岩屑;到北方的Dabieorogenic带(DOB)是暴烈的弧(弧orogen)的来源材料;并且大陆人块clasts从Yangtze地下室(UYB)的uplift是可能的(Jiangnan(江南)高举)。六个沉积周期在学习的节被认出,在武昌的(武昌)形成,并且五在Huajiahu(花家湖)形成。在免职期间,三主要起源起不同作用。量的petrofacies分析从每来源揭示了效果的不同变化,也就是说61.9%(周期我)→54.5%(周期III)→50%(周期IV)→57.9%(周期V)→14.3%(周期VI),14.3%(周期我)→21.2%(周期III)→40%(周期IV)→36.8%(周期V)→14.3%(周期VI),并且23.8%(骑车我)→24.2%(周期III)→10%(周期IV)→5.3%(周期V)→71.4%(周期VI)从圆块,DOB,和UYB分别地。结果证明(1)圆块在早侏罗记期间在可观的激活表现了,但是在中间的侏罗记变弱;(2)精力旺盛构造在中间的侏罗记开始的DOB高举;并且(3)UYB基本上在稳定从对中间的侏罗记早。
