Yannic Wirtz, Geologist with Earth Consultants International (ECI), will present a three-dimensional reconstruction of Nameson and Davis’ balanced cross sections: A regional structural model of Southern California.
Abstract: In the late 1980’s Jay Namson and Thom Davis published a series of balanced cross-sections that became foundational to structural interpretations of Southern California. Built using geometric and kinematic balancing principles and constrained by deep well control and detailed geological mapping by Tom Dibblee, these profiles were widely applied in California’s petroleum industry and academia. Balanced and retrodeformable cross sections proved highly effective in structurally complex basins, providing internally consistent structural models that supported prospect generation, trap definition, and risk reduction. That methodology continues to add value today in refining structural working concepts and evaluating new and mature exploration opportunities in a structurally highly complex environment like California. This project integrates fifteen Namson-Davis cross-sections into a single georeferenced three dimensional structural model built in Blender, an open-source 3D modeling software. By preserving the original balancing logic while extending thrust ramps, flats, folds, and fault linkages between sections, the model reveals crustal-scale continuity not fully apparent in isolated 2D profiles. The result is both a historical synthesis and a modern structural framework, demonstrating the enduring relevance of balanced cross section methodology for internally consistent structural interpretation of Southern California.

SCGS August Meeting
Monday, August 3 at 6:00 PM
South Coast Geological Society invites you to attend our August 2026 meeting and lecture! We are trying out a new meeting location this month.
College Center Building, Room 309
Orange Coast College, 2701 Fairview Road, Costa Mesa, California
Paul Parmentier, former SCGS president, will present a short history of the Congo, which pertains to the modern worldwide use of minerals from that country. Paul will present an overview of the country’s geology, its abundant natural and mineral resources, and the societal significance of the extraction of minerals from the Congo to the world. Your cell phone and EV carry a significant portion of the Congo’s wealth through Coltan, tin, copper, and cobalt exploitation.
