Abstract

Isotope systematics can be interpreted in terms of δ 18O values that were controlled by crystallization temperatures and the δ 18O of connate pore water, and δ 13C values that were controlled by depth-sequential organic matter degradation reactions. Each successive generation of carbonate precipitated at progressively higher burial temperatures from isotopically evolving connate pore water. These carbonate-filled fractures developed during burial and not during uplift. Using crystallization temperature estimates from fluid inclusion data, the change in δ 18O of conate pore water with increasing temperature in the burial environment is modeled. -from Authors
