1. A method of estimating the carbonate grain size of a carbonate rock sample comprising (a) obtaining a carbonate rock sample from a geologic area expected or known to contain carbonate rocks; (b) subjecting the carbonate rock sample to conditions that will cause the release of a detectable amount of carbon dioxide, one or more carbon dioxide-related compounds, or a combination thereof from the rock sample, if present, (c) measuring the amount of carbon dioxide, one or more carbon dioxide-related compounds, or a combination thereof released from the carbonate rock sample, and (d) estimating the carbonate grain size of the carbonate rock sample by measuring the amount of the carbon dioxide, the one or more carbon dioxide-related compounds, or a combination thereof released from the rock sample, wherein less than about 5% of the carbon dioxide, the carbon dioxide-related compounds, or both, originate from carbonate material within the crystalline structure of the carbonate rock.
