| Abstract: |
On the basis of spatial evolution of rock and fossil associations and their environmental significance, in combination with the previous results and comprehensive field and indoor investigation, three depositional systems and seven facies zones have been recognized for the Honghuayuanian sedimentary facies and palaeogeography in Guizhou and its adjacent area.
1. The terrigenous clastic depositional system
1)nearshore facies
2)offshore facies
2. The carbonate platform depositional system
1)open-sea platform facies
2)carbonate platform-beach facies
3)carbonate platform-margin reef facies
3. The shelf-basin depositional system
1)shelf facies
2)basin facies |
