Fracture timing using fluid inclusions, cement texture & accumulation & burial history

The sequence of related papers and their contributions are listed.

Our methods to use diagenesis observations to determine fracture timing have evolved, but the chronology of publication does not match the evolution of ideas. The insight eventually published in Lander & Laubach 2015 was the basis for subsequent research to test or extend the model. Thus key tests of the model (Becker et al. 2010) and adaptation of the model (Gale et al. 2010) were published before Lander’s paper. The listed references document aspects of this approach.
