| Abstract: | The formation of carbonate rocks has had a dramatic sink effect on atmospheric CO2 throughout geological time.The wide global distribution of carbonate rocks and their strong sensitivity to climate change mean that carbonate rock corrosion consuming air/soil CO2 can play an important role in the global carbon cycle.The carbon sink accounts for 12.00%-35.29% of the missing carbon in the global carbon cycle.Using the Pearl River Basin as a case study,we analyzed comprehensively the factors impacting karstific... |
