Ophiolites and Ocean Crust, GSA Penrose Conference

September 13-17, 1998 – Tamales Bay, California
Convener: Yildirim Dilek



A Geological Society of America (GSA) Penrose Conference on ophiolites and oceanic crust brought together a multidisciplinary group of 86 international geoscientists in Marshall, California, from September 13 to 17, 1998. It was jointly sponsored by JOI/USSSP, the National Science Foundation’s Marine Geology and Geophysics Program, and GSA. The purpose of the conference was to: 1) reevaluate existing models of oceanic crust generation, ophiolite formation and ophiolite-ocean crust analogy; 2) explore the possibility of reaching a new consensus on the architecture of oceanic lithosphere; and 3) discuss the significance of ophiolites and oceanic crust for past and present plate tectonic processes.
