吉林省蛟河中生界盆地位于吉林省蛟河县境内,呈北东方向展布,面积约400 km~2。由于该盆地采煤历史悠久,侏罗系上统——白垩系下统发育较全,引起了较多地质工作者的注意。早在一九二九年,王竹泉就对蛟河盆地地层时代进行了研究和划分。以后,不少地质研究人员也相继提出了对盆地地层的划分意见。近年来,杨学林和张普林等人在该盆地做了大量的工作,并对该盆地的地层时代进行了深入一步的研究,各自提出了看法,但迄今认识尚未统一。“河西砾岩”的时代隶属即为其主要争议之一。
The Jiaohe Mesozoic basin in Jilin Province is located in Jiaohe County, Jilin Province and is distributed in the northeast direction with an area of about 400 km ~ 2. Due to the long history of coal mining in the basin, the Lower Jurassic-Cretaceous lower member developed relatively well, attracting more attention from geological workers. As early as 1929, Wang Zhuanquan studied and divided the stratigraphic age of the Jiaohe Basin. Since then, many geological researchers have also put forward their opinions on the division of the basin strata. In recent years, Yang Xuelin and Zhang Pulin and others have done a great deal of work in the basin. They have conducted further studies on the stratigraphic age of the basin and have each put forward their own views. However, so far the understanding has not been unified. The “Hexi conglomerate” belongs to the times is one of the main controversies.
