From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.

以往认为鄂尔多斯盆地的侏罗系延安组为含煤岩系，其他均为不含煤的地层，在近几年来的勘查中，发现直罗组也存在具有一定分布面积的可采煤层，笔者通过直罗组岩石露头、钻孔岩心和测井曲线的分析研究，划分了直罗组沉积相，并探索了直罗组的聚煤规律，对煤层进行了预测。

The research shows that these basins alternate between uplift and concave and that their spreading directions follow certain rule. The 6 NEE-trending basins are of early Jurassic epoch, some of which may contain coal-bearing strata and minable coal seams of Beipiao Formation. The 12 NNE-trending basins are all of early Cretaceous epoch, among which Badaohao, Leijia and Xielintai Basins have relatively good coal-bearing property and can serve as coal-searching prospect area.

研究表明区内这些盆地的呈&隆、凹&相间的格局，且展布方向有一定的规律性，而且呈NEE方向展布的6个是早侏罗世盆地，其中有的可能存在北票组的含煤地层和可采煤层；而呈NNE方向展布的12个均是早白垩世盆地，其中如八道壕、雷家和谢林台等含煤性较好，可作为找煤的远景区。

The Fenghuangshan pluton, which consists of granodiorite and quartz monzodiorite, is the main part of the Fenghuangshan ore field Zircon SHRIMP 206Pb/238U dating shows that the Fenghuangshan pluton formed at (144.2±2.3) Ma, belonging to the Late Jurassic era, which is in accordance with most of metallogenic plutons of the Tongling metallogenic cluster area.

凤凰山岩体为凤凰山矿田的主要组成部分，主要岩石类型为花岗闪长岩、石英二长闪长岩。根据精确锆石SHRIMP测年结果，凤凰山岩体206Pb/238U年龄为(144.2±2.3)Ma，是晚侏罗世形成的一个典型岩体，和铜陵矿集区主要成矿岩体的形成时代一致。

Dynamic evolution analysis of the sandy desertification in the Shenmu area , North Shaanxi, China;2. The stratigraphic order characteristics of coal-bearing strata in the Lower and Middle Jurassic in Shenmu area , North Shaanxi;3. Studies of longitudinal and horizontal distribution of coal reservoir,macroscopic petrographic types,microcosmic petrographic component,pore configuration and permeability,vitrinite reflectance as well as absorbability in coal-bearing formation of Neopaleozoic in Shenmu area of the Ordos Basin indicate that,coal beds are thicker in the east and west,but thinner in the north and south.

通过对鄂尔多斯盆地神木地区上古生界含煤岩系中煤储层的纵横向分布、宏观煤岩类型、微观煤岩组分、孔隙结构与渗透性、镜质体反射率和吸附性能等方面特征的研究，认为：煤层总厚呈东西厚、南北薄的分布特点，煤层厚度满足煤层气开发的要求；多为半亮煤，仅东部边缘地带以半暗煤为主，表现为低含水、中等灰分含量和高挥发分含量的烟煤；煤岩显微组分中，镜质组含量最高，其次为惰质组；孔隙类型以微孔、过渡孔为主。
