The Panoche Giant Injection Complex (PGIC), California, that intrudes into deep-water mudstone-dominated strata of the Moreno Formation. Petrographical microtextural analysis and conventional core-plug analysis of sandstone intrusion samples were compared with similar data derived from micro-CT (MCT) analysis. See Wu et al.
