摘要

IN recent years more and more attention has been paid to the Devonian of the northern belt of Western Qinling because some large-scale or very large-scale fine-disseminated gold ores have been found. Accordingly, the paleogeographical environments ofthe Devonian have become a very important project of concern to sedimentologists. Presently there are two kinds of different opinions on the Devonian sedimentary environments. In the first opinon they were considered as a shallow shelf to a tidal flat, but in the second view, they were thought bathyal-abyssal seafloor canyon-channel turbidity fan systems. Recently some different views to those have been developed by the authors due to a detailed study of the Devonian.
