Examplesofcrustalcrustal Furthermore,crustaldeformation associated with tectonic uplift and exposure of ancient basins often disrupts the lateral continuity of stratigraphic indicators and renders their correlation problematic. From theCambridge English Corpus Although not mentioned in the text,crustalrebound as the weight of ice is removed might make the difference in this scenario as it develops. From theCambridge English Corpus The derivation from or contamination withcrustalmaterial explains the observed similarity of the multi-element patterns to typical upper continental crust. From theCambridge English Corpus With all these processes, interactions between mantle-derived andcrustal-derived magmas control the nature of magmatism in the complex. From theCambridge English Corpus This is valid also for variations among the basaltic members, implying either a heterogeneous mantle source or varying components ofcrustalcontamination. From theCambridge English Corpus Deciphering mantle andcrustalsignatures in subduction zone magmatism. From theCambridge English Corpus Moreover, thecrustalthickness has apparently been augmented over one hemisphere by up to 20 km or so, gradually tapering off near the hemisphere boundaries. From theCambridge English Corpus At shallowcrustallevels, extension can be taken up by tension fractures that sole out onto a normal fault-plane at depth. From theCambridge English Corpus This area is not located at the margins of the earth'scrustalplates where structural stresses may be released as frequent earthquakes and intense volcanicity. From theCambridge English Corpus However, a simple restoration of structural units is worthwhile for determining approximate minimum amounts of uppercrustalshortening and original palaeogeographic positions. From theCambridge English Corpus It underlines the importance of acquiring coincident normal incidence and wide-angle profiles ifcrustalstructure is to be fully characterized. From theCambridge English Corpus Crustalcontamination commonly plays an important role during magma emplacement and its effects must be evaluated carefully. From theCambridge English Corpus If plate tectonics occurs, it must involvecrustalfractionation into components with different buoyancy. From theCambridge English Corpus In some of these inter pretations, amplitudes have been modelled to constrain velocity gradients and fine-scalecrustalstructure. From theCambridge English Corpus Nd-isotope systematics reveal the characteristics of the source from which the magma is derived (including the contribution of oldercrustalmaterial). From theCambridge English Corpus These examples are from corpora and from sources on the web.
