The Carnian period of the Late Triassic is one of the most important periods in the geological history of the past 250 Ma
.
The Carney Flood Deposition Period (CPE, about 234Ma-232Ma) lasted for 1 to 2 million years of heavy rain around the world.
The study used the data of tuffaceous claystone zircon U-Pb dating, high-resolution carbon isotope chemical stratigraphy, palynology, and sedimentology in lake sediments exposed by the ZJ-1 drill core in the Jiyuan Basin on the southern margin of the North China Platform.
Using deposited mercury as an alternative indicator of volcanic activity revealed four discrete pulses of volcanic activity during CPE
.
Each eruption stage corresponds to a negative shift in carbon isotope composition and climate change, lake expansion, and eutrophication
This research provides a key verification (comments of reviewers) for the enhanced global water cycle climate theory triggered by global warming driven by greenhouse gases, and it also deepens our understanding of the diversity of global climate change driven by volcanic activity
