Earth Structure - Laboratories

A set of 3-hour laboratory activities are used in support of PSG&T lecture material, focusing on spatial skills (maps, sections, projections, etc) and applications of major concepts (stress/failure, strain, tectonics, etc). The activities are derived from multiple sources (old and new) and can be shared with instructors for information only. They are not part of the PSG&T offering and serve as examples only. Sources are identified in each activity. Contact:
