Consequences of progressive eclogitisation on crustal exhumation, a mechanical study
The very low water content of the granulitic unit of Holsnøy, in the Bergen Arcs, Norway, caused its partial metastable preservation throughout Caledonian burial end exhumation, leading to the observed mixture of completely eclogitized and uneclogitized rocks. Large-scale eclogite-facies fracturing enabled fluid penetration into the granulite and subsequent eclogitization, and resulted in a ver...
متن کاملImplications of distributed crustal deformation for exhumation in a portion of a transpressional plate boundary, Western Transverse Ranges, Southern California
Spatial and temporal patterns of exhumation are inextricably linked to patterns of crustal deformation because crustal deformation drives rock uplift. A new interpretation of a segment of the Pacific-North America transpressional plate boundary in southern California is analyzed in the context of crustal shortening, rock uplift, and exhumation. Deformation is partitioned between two structural ...
متن کاملTectonic evolution of a continental subduction‐exhumation channel: Variscan structure of the basal allochthonous units in NW Spain
[1] A regional study starting from detailed geological mapping has been carried out in the Malpica‐Tui Complex of Galicia in NW Spain. The complex is formed by two units representing pieces of the external edge of Gondwana, subducted and exhumed during the Variscan collision. The study shows that synsubduction and early synexhumation structures in continental subduction channels tends to be obs...
متن کاملActive continental subduction and crustal exhumation: the Taiwan orogeny
It is generally accepted that continental subduction and crustal exhumation play an important role in the evolution of many orogenic belts. A variety of geological evidence suggests that continental crust is occasionally subducted to depths of tens to perhaps 150 km (e.g. Chopin, 1984; Dewey et al., 1993; Matte et al., 1997). Recently, a series of simulations (Chemenda, 1993; Chemenda et al., 1...
متن کاملThermal modeling of continental subduction and exhumation constrained by heat flow and seismicity in Taiwan
The thermal evolution of crustal exhumation subsequent to the subduction of the continental margin is modeled through numerical solutions to the two-dimensional heat conduction equation. The boundary conditions used in the modeling are basically constrained by available geophysical and geological observations in the Taiwan area. Temperature distributions are calculated at one-million-year inter...
