Data sets

Carbon and oxygen isotope values of bulk carbonates for Castellas Fault zone and D19 fault zones, La Fare anticline I. Aubert et al.

Short summary
In carbonate rocks, fault zones influence the fluid flows and lead to important diagenetic processes modifying reservoir properties. The aim of this study is to identify the impact of two polyphase fault zones on fluid flows and reservoir properties during basin history. We determined petro-physic and diagenetic properties on 92 samples. This study highlights that fault zones acted as drains at their onset and induced fault zone cementation, which has strongly altered local reservoir properties.
