CaCO3溶解在碳酸盐补偿深度(CCD)。< / p >

However, this paper suggests that some CaCO3 can exist below the CCD.

My question arises from a discussion in this answer.

The question is whether some of the CO2 emitted by volcanoes in subduction zones comes from the melting of CaCO3 sediments in the slag.

Has there been any isotopic study clarifying the provenance of CO2 from volcanoes in subduction zones?
