Study on mine geological characteristics in Beichuan area
LIU Ming;School of Earth Sciences, Chengdu University of Technology;
Mine geological research in Beichuan area is the most important sequence stratigraphic division, and the key is to identify the sequence division of the interface, the interface can be used to determine the sequence including the sequence interface, flooding surface, of which the most important is to identify the sequence of the bottom, which is the basis and premise of sequence division. The geological characteristics and sequence stratigraphic division of the two elements of the marine leaching system tract and the highstand system tract in Beichuan area have obvious prospecting marks and good prospecting prospect.
