| Abstract: | In response to the doubts about our previous study raised by Wang Yang in his article Field occurrence and origin of the Xinglonggou igneous rocks in Beipiao,Western Liaoning Province and geological significance,here we detailedly describe our geological investigation on the Xinglonggou formation of the Early Jurassic in Beipiao area.Focusing on the issues that were questioned,this paper mainly discusses our field observation and isotopic dating of the Xinglonggou formation.Based on a newly obtained Ar-Ar a... |
