| 摘 要： | 晚三叠世须家河组沉积期是重庆地区的重要成煤期。通过对须家河组含煤地层沉积环境的分析,认为区内须家河组厚度由东南向西北逐渐增大,主要发育河流冲积平原、湖滨-三角洲及湖泊沉积体系,具有工业价值的煤层主要形成于须家河组一段、五段和七段的湖滨-三角洲沉积体系中。最有利的聚煤中心分布于达州—开江—梁平以及永川—荣昌两个区域。

| Abstract: | The Late Triassic Epoch Xujiahe age is an important coal-forming period in the Chongqing area.After coal-bearing strata sedimentary environment analysis of the Xujiahe Formation,considered that the thickness of the formation is increasing from southeast to northwest,mainly fluvial plain,lakeshore-deltaic and lacustrine sedimentary systems have been developed.Coal seams with commercial value are mainly formed in the first,fifth and seventh members of Xujiahe Formation lakeshore-deltaic sedimentary system.Opt... |
