甲、地层:在区内仅见震旦纪和第四纪地层 (1.)震旦纪地层:自上而下可分为六层:6.变质页岩层:以暗蓝灰色板状角页层为主夹片状石英岩及石灰岩层,厚度300——350公尺。5.矽质石灰岩层: 下部为黑灰色石英岩与棕色石英岩之互层。上部以石灰岩为主,厚度在801 公尺上下。4.黑色页岩层:以黑色页岩为主,夹石英岩多层,厚度约计0 50公尺。3.暗色石英岩层:以暗蓝灰色石英岩为主,中夹黑页岩,厚度 3 50——400公尺。2.黑色页岩砂岩:下级为黑色页岩,棕灰或蓝灰之石英砂岩及石灰岩之累层所成,上部以黑色员岩为主,共厚约 400公尺。1. 淡色石英岩层:以白色块状石英岩为主,以上各层均相连续,据其岩性及层次可与华北的下震旦纪各层相比较。 (2.)第四纪地层:自上而下为:3.黄土:为闪生黄土,富白砂质,分布沟谷一带。2.鄂博层:砾岩成角砾岩,砾石成为铁矿石,成为石灰岩,胶结物均为石灰质,不具层次,现露头已剩残余。厚度最大处不过三公尺。1.铁矿砾石堆积:仅见於试沟内,由铁矿崩解后就地堆积,中充黏土,尚未胶结,?
A, strata: Only the Sinian and Quaternary stratigraphy in the area (1.) Sinian strata: top-down can be divided into six layers: 6. Metamorphic shale layer: the dark blue-gray plate corner layer The main clip-like quartzite and limestone layer, the thickness of 300 - 350 meters. 5. Silical limestone: The lower part is dark gray quartzite and brown quartzite interbedded. Upper mainly limestone, thickness of 801 meters up and down. 4. Black shale: black shale-based, multi-layered quartzite, thickness of about 0 50 meters. 3. Dark quartz rock layer: mainly dark blue-gray quartzite, black shale in folder, thickness 3 50 - 400 meters. Black shale sandstone: the lower is black shale, brown ash or blue-gray quartz sandstone and limestone accumulation of the upper part of the black rock, the total thickness of about 400 meters. 1. Light-colored quartzite: white block quartzite-based, all the above-mentioned layers are continuous, according to its lithology and level can be compared with the North China under the Sinian layers. (2.) Quaternary strata: top to bottom: 3. Loess: Shishan loess, rich white sandy, distribution gully area. 2. Obo layer: Conglomerate breccia, gravel to become iron ore, a limestone, cement are calcareous, non-hierarchical, there are now remaining remnants of the outcrop. However, the maximum thickness of three meters. 1. Iron ore gravel accumulation: only found in the test trench, after the disintegration of iron deposits on the spot, filled clay, not yet cemented?
