戈塘金矿中含炭硅质角砾岩成因浅析

The Genesis of C-bearing Siliceous Breccia in the Getang Au-deposit

通过对含炭硅质角砾岩的岩石学、岩石化学及地球化学特征的研究,论证了该岩层是由沉积作用形成,其物源主要来自上覆龙潭组沉积地层。

The Getang Au-deposit occurs in the C-bearing siliceous breccia at the bottom of the upper Permian Longtan Formation.Astudy of the peotrological,lithochemical and gechemical chracteristics demonstrates that this rock formation was formed bysedimentation and its source materials were derived from overlying sedimentary stratum of the Longtan Formation.
