1 | The Chengzihe Formation in Zhangxin area of Jixi basin, Heilongjiang Province is intruded by the algorite sill. | |
2 | Clay minerals in the outcropped sandstone from Lower Cretaceous Chengzihe Formation and Muling Formation in Jixi Basin were analyzed by X-ray diffraction. | |
3 | The study indicates that the favourable area for gas is located in the Fuxing slope in the east of Suibin depression. | |
4 | Through analysed workable coal seam change features, coal-rich zone, the distribution features of coal accumulation Center, describe the pattern of Chengzihe River Formation in Jixi Coal Basin. | |
5 | 近年来鸡西含煤盆地早白垩世海相沟鞭藻及早期被子植物化石的不断发现,为确认城子河组及其下伏滴道组、上覆穆棱组的时代属早白垩世提供了重要的依据。 On the basis of tectonic evolution in Junggar coal basin and taking coal mineral as "the fossil" and by way of studying the basin formation and tectonic evolution in every stage. |
