WebSome faults are older than some intrusions and some intrusions are older than some faults. I can help you understand this situation a bit better by explaining how faults form. Faults form when shear stress on rock exceeds its tensile strength. When you apply enough shear stress to cool, brittle, rigid rock, then faults form. WebAug 1, 2015 · Sheet intrusions typically do not initially intrude as bodies of magma with significant along-strike extents (e.g., Rickwood, 1990; Schofield et al., 2012b). Instead, the initial phase of emplacement is commonly dominated by the propagation of thin, discrete magma segments, which may be vertically and/or laterally offset from each other ( Fig. 3 … WebPrinciple of Cross-Cutting Relationships: Deformation events like folds, faults and igneous intrusions that cut across rocks are younger than the rocks they cut across. ...
