| 摘 要： | 刘房子盆地为松辽盆地东缘～断陷型盆地。盆内充填晚中生代陆相碎屑岩含煤建造,富含煤、膨润土。大羊草沟组为主要含煤层位;主要可采煤层形成于曲流河体系的岸后沼泽;钠基膨润土系河流搬运至浅水湖泊与沼泽中沉积成因;刘房子盆地的演化,既具区域发展的共性,又有其自身的特点。本文在综合分析基础上提炼出网结河体系与曲流河体系的聚煤模式;总结了煤和膨润土的赋存规律;并指明进一步勘探、开发、利用方向。

| Abstract: | The Liufangzi basin, situated in eastern margin of the Songliao basin, is a fault basin. It is filled with coal formation of late Mesozoic terrestrial facies clastic rock and bentonite. The Dayangcaogou formation is the main coal-bearing stratum; the main workable coal beds were formed in back swamp of meandering river system ; the basin evolution is common with areal development, but has the unique characteristics itself; Na -bentanite was formed in shallow water lacus and swamp. The Main coal accumulating models of the Liufangzi basin are the anastomosing streams and the meandering river systems. At last in this papar, the writer points out the directions of explorating and exploiting of coal and bentonite. |
