太原西山煤田太原组砂岩的物源分析
|
摘要
太原西山七里沟剖面为我国华北石炭-二叠系标准层型地层剖面。采用岩石学和重矿物学方法对太原西山七里沟剖面太原组砂岩进行了研究,结果表明:太原组砂岩的母岩类型主要为富含燧石结核或条带的沉积岩,部分为岩浆岩和变质岩。Dickinson碎屑组分三角图解显示太原组砂岩的物源区为再旋回造山带。结合古水流特征,认为太原组砂岩的物源主要来自华北北缘的内蒙古隆起。物源区的风化剥蚀从寒武-奥陶系的富含燧石结核或条带的碳酸盐岩开始,向下逐渐剥蚀到新元古界震旦系的石英岩。
The standard stratotype section of Carboniferous-Permian coal-bearing of North China located in Qiligou section of Xishan,Taiyuan. According to statistical analysis of sandstone fragment component and heavy mineral in the sandstones of Taiyuan Formation came from the Qiligou section in Xishan coal field,Taiyuan,the parent rocks of the sandstone of Taiyuan formation mainly are the chert strip or nodule-bearing clastic rock,partly are the magmatic rocks and metamorphic rocks. The Dickinson triangular plots of clastic component indicate the sediments of Taiyuan Formation are mainly derived from recycled orogenic source. Combining with the palaeocurrent analysis,the provenance of Taiyuan Formation mainly come from the Inner Mongolia Paleo-uplift. The Inner Mongolia Paleouplift was steady uplifted by subduction of the Paleo-Asian Ocean Plate underneath the northern NCC,the weathering and denudation of the provenance started from the chert strip or nodule-bearing Carbonate and clastic rock of the Cambrian-Ordovician,to the quartzite of the upper Proterozoic Sinian.
