Cheng Rihui, Zheng Herong, Lin Changsong. STRUCTURAL FAULT TERRACE AND SAND BODY PREDICTION:AN EXAMPLE FROM FULIN AREA,ZHANHUA SAG[J]. 1999, 20(3): 203-206.DOI: 10.11743/ogg19990305.
Structural fault terrace zone incloses steep and gentle slopes.The control of the both kinds of slopes on sandbodies are different due to topography.During lowstand
alluvial fan
fan delta developed on steep slope while fluvial plain
small alluvial fan and fan delta developed on gentle slope.During progression period
fan head
midfan and far end of alluvial fan or fan delta devloped on different fault terraces
turbidite fan and gravity flow deposites developed on deep depressed position
while retrogradation of predepositional sandbodies developed on the gentle slope.During high stand
wedge and lense shaped deposits of delta progradation developed on the whole ares.Besides
fault activities and their migration directions also influenced the distribution of sandbodies.These regularities could be used to predict sandbodied on seismic profile.
