英文摘要 | A widespread provenance shift recorded by passive margin strata of western Laurentia, from predominant Stenian (1.2-1.0 Ga) detrital zircon age components to their absence, occurred during the Neoproterozoic-Cambrian Sauk transgression and is commonly used as a ca. 540 Ma chronostratigraphic marker throughout the west/south-western United States. However, in Neoproterozoic-Cambrian strata of this region, we identify a probable shift from distal to more proximal Stenian-age zircon sources before a diachronous loss of Stenian detrital zircon age components. We suggest these provenance patterns reflect progressive subsidence of the passive margins surrounding Laurentia and concomitant relative uplift of the Transcontinental Arch, a broad and segmented northeast-southwest trending topographic high across the Laurentian midcontinent possibly due to lithospheric flexure. The Transcontinental Arch segments align with transverse rift structures of the Neoproterozoic-Cambrian Iapetan margin and the Mesoproterozoic Midcontinent Rift, perhaps reflecting rejuvenation of midcontinent lithospheric weaknesses during the Sauk transgression and final Rodinia breakup. |
