Description:
The Triassic marine strata are well developed and preserved completely in the Xingyi - Guanling area, Guizhou Province. In this area, sediment differentiations are obvious and marine reptile fossils are abundant and perfect. They will provide important references for us to better understanding the effect of eco-sedimentary process during the evolution of carbonate platform and ecological response and feedback mechanisms during extreme climate processes in the Triassic. The fieldtrip aims at illustrating the stratigraphic, sedimentologic and paleontological evolution of Xingyi-Guanling area.
(1) The Guanling - Yongning Triassic section and Guanling Fossil National Geopark. This section completely records the formation and evolution process of carbonate factory during the lower to middle Triassic palaeogeographic environment. Furthermore, the Guanling biota, which is discovered in upper Triassic part of this section, is a rare marine fossils reservoir around the world.
(2) The Triassic "S" shape sedimentary facies transformation zone. The facies transformation zone between the Yangtze carbonate platform and the Nanpanjiang Basin. Controlled by paleotopography and sediment source, the facies transformation had an “S” shape banding distribution in the Xingyi - Guanling area. It clearly shows the middle Triassic sedimentary system evolution of “platform - slope - basin” and carbonate factory breakdown during Carnian Pluvial Episode (CPE).
(3) The Xingyi Triassic section and the Museum of Xingyi National Geological Park. This section is characterized by community successions of the Xingyi biota. Moreover, seismic-tsunamic and storm depositional sequences are well developed in the middle - upper part of Falang Formation. It offers a unique sedimentological viewpoint to us to systematically understand the climatic, ecological and taphonomic evolution in the middle - upper Triassic.
In addition, the special stratigraphic, tectonic conditions and the unique hydrogeological properties result in the rich combination of karst forms makes a gorgeous landscape of geological relics in Xingyi - Guanling Area.
