摘要：
In a marl formation that was subjected to low-temperature metamorphism, free gases and groundwaters were sampled and compared with the bulk and isotopic compositions of fluid inclusions. Results indicate different sources for gas (derived thermally from kerogen) and water (which represents a mixture of connate and metamorphic water). No indications exist for later interactions of the rocks with meteoric waters.
