河东煤田离柳矿区枣林沟石炭-二叠系沉积地层及岩石学特征
|
摘要
为进一步探明河东煤田离柳矿区沉积地层和岩石学特征,通过野外实测剖面和显微岩相学方法研究了离柳矿区枣林沟地层和岩石学特征。结果表明:该区石炭系厚约14. 5 m,仅存上石炭统本溪组C_(2b)和太原组下段C_(2t);二叠系厚度超过112m,包括太原组上段P_(1t)、山西组P_(1-2s)、下石盒子组P_(2x)和上石盒子组P_(2-3s)(未见顶)。可见该区沉积地层主要为二叠系,并以陆源碎屑岩为主,含少量碳酸盐岩和铁质岩。铁质岩主要组成矿物为褐铁矿,碳酸盐岩仅见于太原组上段。
In order to further explore the sedimentary strata and lithologic characteristics of Liliu mining area in Hedong coalfield,field measurement section and microlithology were used to investigate the stratigraphic and petrological characteristics. The results show that the Carboniferous in this area is about 14. 5 m thick,only the C_(2b) of the Benxi Formation of the Carboniferous and the C_(2t) of the lower part of the Taiyuan Formation; The thickness of the Permian is more than 112 m,including the P_(1t) of the upper Taiyuan Formation,the P_(1-2s) of the Shanxi Formation,and the P_(2x) of the Lower Shihezi Formation and upper Shihezi Formation P_(2-3s)( not seen its top). It's concluded that the sedimentary strata in this area are mainly of the Permian and lots of terrigenous clastic rocks with a small amount of carbonate rocks and iron rocks. The main constituent mineral of iron rock is limonite. Carbonate rock is only found in the upper part of Taiyuan Formation.
