苏家河—贝家庄含煤岩系沉积演化规律的研究 专 业：资源勘查工程 摘 要 煤炭在我国国民经济和能源结构中，都占据着非常重要的地位。长期以来，煤炭在我国一次能源消耗中占70%左右，而且在今后相当长的时期内，以煤炭为主的能源状况不会改变。煤炭不仅是重要的能源，而且也是重要的工业原料。加快我国煤炭生产建设，实现小康生活，增强国家的经济实力，不断满足人民生活的需要，是21世纪煤炭工业发展的紧迫任务。 本文收集了宜川（南）韩城（北）苏家河—贝家庄地区的地形地貌，地层岩性，地质构造，水文地质和钻孔柱状图等资料，结合在野外填图和室内编图的基础上进行分析和总结。确定区内地层层序，详细划分地层，研究其沉积环境特征，根据总结的区内沉积环境特征，着重分析苏家河—贝家庄地区的沉积特征，结合实习的调查，总结其含煤岩系沉积演化规律。 关 键 词：地层 沉积体系 晚古生代 古地理演化 三角洲 研究类型：理论型 Subject : Sue home river-the home of coal zhuang sedimentary rock the research on the laws of evolution Specialty : Resources Exploration Engineering ABSTRACT Coal in the national economy and the energy structure, holds a very important position. Long-term since, our country a coal in the energy consumption of about 70%, and a long time in the future, the coal-dominant energy status will not change. Coal is not only the important energy, but also is the important industrial raw material. The acceleration of Chinas coal production and construction, a well-off life, increase the countrys economic strength, and satisfy the peoples living needs of the 21 st century, the development of the coal industry is the urgent task. This paper collected YiChuan (south) HanCheng (north) Sue home-a river in the home village of landform, stratigraphic lithology, geological structure, geological and hydrogeological and drilling bar chart data, combined with in the wild mapping and indoor make up picture on the basis of the analysis and summary. Determine the sequence, the detailed area layer, and study the classification of strata sedimentary environment, according to the characteristics of sedimentary environment characteristics in the summary on the analysis of the home-a river house Sue zhuang region, combining with the practice of sedimentary characteristics of the investigation of coal, and to sum up the sedimentary rock evolution rule.
