云南第三纪沉积盆地,约有270多个,几乎遍布全省。到目前发现有煤并进行了不同程度地质工作的有114个。这些盆地形态各异,大小不一,大者几百平方公里,小者零点几平方公里;含煤建造的厚度几十米至两千余米;煤层厚度几米至两百余米;储量几十万吨至几十亿吨,含煤盆地成因类型较多,是我国研究第三纪含煤建造的良好地区。 本文试图通过对诸含煤盆地的成生、发展、沉积特征、含煤规律的分析,进一步提出云南第三纪煤盆地的成因类型分类,希有关同志批评指正。
Yunnan Tertiary sedimentary basin, about more than 270, almost all over the province. So far there are 114 found coal and geological work to varying degrees. These basins are of different shapes and sizes, with large ones of several hundred square kilometers and small ones of a few square kilometers. The thickness of coal-bearing buildings ranges from several tens of meters to two thousand meters; the thickness of coal seams ranges from several meters to two hundred meters; Tons of tons to billions of tons, more generative types of coal-bearing basins, China is the study of Tertiary coal-rich areas. Based on the analysis of formation, development, depositional characteristics and coal-bearing laws of coal-bearing basins, this paper attempts to further classify the genesis types of the Tertiary coal basins in Yunnan Province, and hopefully the relevant comrades will criticize and correct them.
