GSA Bulletin celebrates GSA's 125th Anniversary with new geologic time scale
Date:12/27/2012

. Results reveal that coseismic faulting occurred about 50 million years ago, through coseismic reactivation of a Late Ordovician (460-440 million years) ductile shear zone, implying a period of apparent tectonic quiescence of as much as about 390 million years. The study highlights the inherent difficulty in investigating structures characterized by long periods of tectonic quiescence, for which an accurate evaluation of recurrent periods of fault movement is precluded.


Continental and oceanic core complexes
Donna L. Whitney et al., University of Minnesota, Minneapolis, Minnesota, 55455, USA. Posted online 21 Dec. 2012; http://dx.doi.org/10.1130/B30754.1.

Core complexes are domal geologic structures that form when continental and oceanic lithosphere extends and, as a result, formerly deep rocks rise toward the surface below normal faults. Because deep rocks are brought close to the surface, the formation of core complexes results in the transfer or large amounts of heat and material from deep to shallow. Core complexes offer a glimpse of the deep crust and upper mantle because these rocks are carried upward as the crust flows to fill the gap created by extension of the upper crust. Formation of these structures is related to crustal evolution, global element cycles, heat budgets of continents and oceans, and ore formation. In this review, Donna L. Whitney and colleagues provide a survey of about 40 years of core-complex literature, discuss processes and questions relevant to the formation and evolution of core complexes in continental and oceanic settings, highlight the significance of core complexes for lithosphere dynamics, and propose a few possible directions for future research.
