英文摘要 | Earliest Cordilleran magmatism in the southwestern United States is recorded by a belt of Triassic plutons that intrude Proterozoic basement of the Mojave crustal province and its cratonal/miogeoclinal cover. The belt extends from the western Mojave Desert through the Transverse Ranges to the Colorado River trough. Triassic plutons are predominantly alkali-calcic, Fe and Sr-enriched quartz monzodiorites and monzonites. The northern part of the belt is composed of two older plutonic suites (241-231 Ma) which are high K to shoshonitic; the southern part of the belt is a younger (218-213 Ma), sodic-alkalic suite. The plutonic record in southern California suggests a short-lived, southward younging continental margin are setting for emplacement of Triassic plutons, superimposed on a continental margin modified by sinistral transform faulting Triassic plutonism in this region was followed by a magmatic lull prior to the onset of voluminous Middle to Late Jurassic Cordilleran arc magmatism. |
