We present zircon rare earth element (REE) compositions integrated with U-Pb ages of and whole-rock geochemistry from 29 volcanic tuffs preserved in the Karoo Supergroup, South Africa, to investigate history magmatism southern Gondwana. Whole-rock suggest a subduction-driven magmatic arc source for early (before 270 Ma) middle Permian (270–260 tuffs. After ca. 265 Ma, deposits transitioned toward intraplate shallow-sourced magmatism. Zircon REE chemistry that magmas were oxidizing, U- heavy...

ABSTRACT Deep-sea fan sediments carry physical and chemical signatures that reflect the conditions under which their native landscapes evolved. Fans are long-lived, strongly net-depositional heaps of terrigenous debris, in some cases directly connected to a major river catchment. Here we use recent findings from deep-sea fans around world reason modern might be our most continuous record Cenozoic landscape change over large geographic scales. We opt for multiple indicate shifts composition,...

Abstract We report a new ecological refugium for the Cheirolepidiaceae family (pollen form genus Classopollis) in Paleocene Lower Wilcox Group Gulf Coast of southeastern Texas based on palynological analysis four wells. The were once thought to have gone extinct at Cretaceous–Paleogene (K/Pg) boundary or earlier North America; however, similar refugia this previously been reported China, Argentina, and potentially Rocky Mountains United States. highest relative abundances Classopollis pollen...

Terrigenous marine sediment records the landscape response to climate and tectonic perturbations. Here, we determined source of Miocene–Pleistocene debris in western Gulf Mexico (WGOM) understand changes supply during a greenhouse-glacial transition. Sediment composition at Deep Sea Drilling Project (DSDP) Sites 3, 87, 89–91 shows reversal provenance following onset Pleistocene glaciation. During Miocene time, was supplied deep WGOM from tectonically active, tropical highlands southern...

Sediment eroded from continents during ice ages can be rapidly (<104 years) transferred via rivers to the deep-sea and preserved in submarine fans, becoming a viable record of landscape evolution. We applied chemical weathering proxies zircon geo-thermo-chronometry late Pleistocene sediment recovered Mississippi fan, revealing interactions between Laurentide sheet (LIS) broader Mississippi-Missouri catchment ca. 70,000 10,000 years ago (70 10 ka). contribution Missouri fan was low 70 30 ka...

ABSTRACT Exceptional exposure of the forearc region NW Peru offers insight into evolving convergent margins. The sedimentary fill Talara basin spans Cretaceous to Eocene for an overall thickness 9000 m and records within its stratigraphy complicated history plate interactions, subduction tectonics, terrane accretion, Andean orogeny. By early Tertiary, extensional tectonism was forming a complex horst graben system that partitioned series localized depocentres. strata record temporal...

Subduction zones are common tectonic features central to large-scale crustal and elemental cycling, they accompanied by basins often with thick sedimentary fill structures suitable for hydrocarbon preservation. However, significant production occurs in only a handful of subduction zone locations. Here we explore our current understanding the controls on systems associated zones, terms strongly variable conditions inherent this setting that either favor or limit petroleum production, context...

Over the last few decades, concept of sustainability has been proposed and championed as answer to impending challenges our society will be facing in future. It a rallying opportunity for broad earth sciences community good starting point such impact societal policy decisions; however, it an we have largely missed thus far.
