摘要
以陕北神木地区1∶5万区域地质调查成果资料为基础,运用层序地层学的理论和方法,系统分析与研究了该区中生代含煤岩系的层序地层特征、盆地充填样式,初步建立了该地区区域岩石地层模型。本文反映了该区层序地层学研究的新进展,对应用层序地层学理论进行成煤规律分析及成矿预测进行了有益的探索。
The Jurassic coalfield of north Shaanxi, is the largest coalfield probed in China at present. Based on the production and data of regional geological survey in Shenmu area of north Shaanxi with 1∶50 000, this paper systemically analyzes the stratigraphic order characteristics of coal-bearing strata in Mesozoic, and the sedimentary patterns in the basin, and the rock-stratum model in this area is established at the first step. Meanwhile this paper reflects the newest progress of the sequence stratigraphic study of the area, and deals with the helpful research on applying the sequence stratigraphy theories to the analysis of the process ore-forming and prognostication ore-forming.
