A 3-D geodynamic model of lateral crustal flow
نویسندگان
چکیده
Although the Andes are believed to have resulted mainly from crustal shortening, the shortening history remains debated and appears to require lateral (along-strike) crustal flow. Three-dimensional viscous flow modeling shows that, within geological uncertainties, the Andes may have been produced by either Neogene shortening alone or with significant preNeogene shortening. These scenarios require major along-strike crustal flow and predict significantly different histories of uplift

Simulation on seismogenic environment of strong earthquakes in Sichuan-Yunnan region, China
Based on 43 Harvard CMT solutions in Yunnan region, GPS observations from 1999 to 2004 by China Crustal Movement Observatory Network, and results from SKS splitting and Pn fast wave anisotropy, we obtained the average directions of principle stress fields at different depths by average angle method. Then we further analyzed the coupling difference between geodynamic parameters in different tect...

[1] We welcome the comment from Miller et al. [2012] and the opportunity to address their concerns and to expand on several aspects of the proposed geodynamic model in Wells et al. [2012]. Many of the points raised in the comment concern Late Cretaceous crustal anatexis and extension, aspects of the proposed geodynamic model that were developed in more detail in Wells and Hoisch [2008]. We addr...
متن کاملPetrology and Presentation: A Seven-Stage Model forGeodynamic Evolution of the Northeast Region of Birjand,East of Northern Lut, Eastern Iran
The northeast region of Birjand is located in Lut structural and geological province. In this area we can distinguish two separate volcanic rock groups: intermediate to acidic volcanic rocks, including dacite, andesite, rhyolite and trachyandesite; and basic rocks, including basaltic andesite, mugearite and basalt. In this region, intermediate to acidic rocks, which belong to the Eocene-Miocene...
متن کاملEvidence of micro-continent entrainment during crustal accretion
Simple models involving the gradual outboard accretion of material along curvilinear subduction zones are often inconsistent with field-based evidence. A recent study using 3-D geodynamic modelling has shown that the entrainment of an exotic continental fragment within a simple subduction system can result in a complex phase of growth. Although kinematic models based on structural mapping and h...
متن کاملNew geodynamical model for the regional Tertiary extension during the Zagros orogeny: A transtensional arc?
The Zagros orogeny in Iran is associated with two successive geodynamic events during the Tertiary period, a Paleogene NE-directed regional crustal extension followed by a Miocene NW-directed regional crustal extension and a magmatic flare-up. The current study was undertaken to reanalyze previous structural work developed on the extensional Chapedony metamorphic core complex in Central Iran ex...
