Middle Devonian Rocks and Sedimentary Environment Analysis in Beichuan Ganxi Area

Through detailed analysis of the area aspects of Beichuan Ganxi Middle Devonian strata of rock types, sedimentary structures, cross-sectional structure access to the sedimentary environment Guanwushan group, gold and precious stones group raised Maba group. Recognizing that the region is a mixed sedimentary strata, that mixed sedimentary types are divided into inner and carbonate terrigenous clastic deposition and interaction between the two components of the same rock, sedimentary environment for mixed continental shelf, continental shelf and broken down into the open confined to two secondary shelf sedimentary environment.
