Sketching, particularly in field settings, is a common but powerful means of communication and visualization in the geosciences. Here, we investigate the range of sketch types and annotations made by expert geoscientists and non-geoscientists during a field trip to the Hat Creek fault zone (northern California) taken during the 2013 AAPG Hedberg Research Conference. Participants (N=42) included geologists and seismic interpreters employed in the oil and gas industry (n=20), geologists employed in academia (n=16), and non-geoscientist software developers and cognitive scientists (n=6). A total of 361 sketches of the normal fault system were collected during stops at three field...

3-D Structural Interpretation: Earth, Mind, and Machine
Three-dimensional geologic interpretation of surface and subsurface data requires integration and application of both geologic knowledge and spatial cognitive skills. Much surface geologic mapping still employs pen and paper techniques, but subsurface interpretation is usually accomplished using sophisticated visualization software. In both cases, successful interpreters use mental models that bridge internal and external forms of 3-D visualization to construct 3-D geologic interpretations. This AAPG Memoir 111 sets out to understand more about the convergence of geology, 3-D thinking, and software, which collectively provide the basis for truly effective interpretation strategies. It should appeal to all geologic interpreters, and especially those who investigate and teach interpretation skills.
