北川地区矿山地质特征研究

Study on mine geological characteristics in Beichuan area

北川地区矿山地质研究中最关键的是层序地层划分,而层序划分的关键是有关界面的识别,可用于确定层序的界面包括层序的界面、泛面等,其中最重要的是层序底界面的识别,这是层序划分的基础跟前提。北川地区矿山地质特征及层序地层划分含海浸体系域和高水位体系域的二元结构,其具有找矿标志明显,找矿前景好等特点。

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.
