摘要
Through geological profile and trunk route survey,the characteristics of sedimentary facies of Huangmaqing Formation in Luzong basin and its peripheral regions has been studied.Through testing of samples,the contents characteristics of Cu,Pb,Zn,Au,Ag and some other metal elements at the upper Huangmaqing Formation has been analyzed.Further more,the accumulation beds of Cu and its mechanism of concentration has been tentatively discussed. The mudstone and silty mudstone of Upper Huangmaqing Formation developed in interdistributary bay,thus mudstone content can reflect its development.The litho-facies paleogeography graph is plotted by ratio of rocks(contour map of mudstone/sandstone).The four areas reflect the plane development of interdistributary bay microfacies and also the Cu-bearing stratiform.The litho-facies paleogeography graph manifests the Cu-bearing stratiform of Huangmaqing Formation is well developed to the east of Yijinqiao-Shiji in south-central basin.
