资兴三都煤田是湖南省三大煤田之一,是唯一属于晚三迭世的含煤建造,有悠久的研究和开发历史。本世纪三十年代王晓青、刘元镇、谭锡畴等老一辈地质工作者曾在此做过地质调查工作。解放后129队、省煤田勘探公司一队、三队、五队都在此做过勘探工作。长期以来,人们都认为含煤建造是纯陆相沉积,1978～1980期间武汉地质学院陈钟惠老师等在三都地区进行了大比例尺的地质测量,对地层和沉积环境等进行了研究,认为本区晚三迭世含煤建造为海陆交互沉积。作者和毕业生等六人,于1986年在本区做了一些工作。本文的目的在于小结我们的研究成果,探讨含煤建造的沉积环境,分析主要煤层的聚煤规律和成煤模式,从而为煤炭资源的开发利用提供依据。 Zixing Sandu Coalfield is one of the three major coalfields in Hunan Province. It is the only coal-bearing construction belonging to the late Triassic and has a long history of research and development. In the thirties of this century, Wang Xiaoqing, Liu Yuanzhen, Tan Xincu and other geologists of the older generation have done geological surveys. After the liberation of 129 teams, provincial coal exploration company team, three teams, five teams have done in this exploration work. For a long time, coal-bearing construction was considered as purely continental deposition. During 1978 ~ 1980, Chen Zhonghui from Wuhan Geological Institute conducted large-scale geological surveys in Sandu and studied the strata and sedimentary environment. Late Triassic coal-bearing construction for the interaction between land and sea sediments. Author and graduate six people, in 1986 to do some work in this area. The purpose of this paper is to summarize our findings, discuss the sedimentary environment of the coal-bearing construction, and analyze the coal-forming laws and coal-forming patterns of the major coal seams so as to provide a basis for the development and utilization of coal resources.
