摘要
Slope fan sediment is of a kind of the gravity flows. It is also developed in continental fault basins. Some conglomerate bodies with heavy thickness, coarse grains and quickly changed facies occur in the slope break of the first Member of Tenger Formation in Uliastai sag, Erlian Basin, Inner Mongolia. Based on the examination of cores, well logs, 3D seismic and petrographic data, it is concluded that the conglomerate bodies belong to slope fan formed by sediment gravity flow in the low-stand systems. With the classification of the slope fan in the studied area, the planar distribution of the slope fan deposits is analyzed. A sedimentary facies model of the studied area is set up.
