Abstract. Detrital zircon geochronology by laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) is a widely used tool for determining maximum depositional ages and sediment provenance, as well reconstructing routing pathways. Although the accuracy precision of U–Pb measurements have improved over past 2 decades, Pb loss continues to impact ability resolve age populations biasing affected toward younger apparent ages. Chemical abrasion (CA) has been shown reduce or...

Detrital zircon geochronology by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) is a widely-used tool for determining maximum depositional ages, sediment provenance, and reconstructing routing pathways. Although the accuracy precision of U-Pb measurements has improved over past two decades, Pb-loss continues to impact ability resolve age populations biasing affected toward younger apparent ages.

We conducted ichthyological surveys in the Biata, Geneshuaya, Benicito, and Yata Rivers, as well Dos Naciones Lagoon. recorded 182 species, including new records for Bolivia, such Jupiaba citrina Zanata & Ohara, 2009, Moenkhausia melogramma Eigenmann, 1908, Spinipterus cf. acsi Akama Ferraris, 2011, Tatia gyrina (Eigenmann Allen, 1942), Cetopsidium orientale (Vari, Ferraris Keith, 2003), Nemuroglanis furcatus Ribeiro, Pedroza Rapp Py‑Daniel, Batrochoglanis melanurus Shibatta...
Estratigrafía de un Lagerstätte neotropical del Mioceno medio (localidad La Venta, Colombia). El Konzentrat-Lagerstätte la localidad Venta registrado en el Grupo Honda contiene información invaluable sobre respuesta biótica a los cambios climáticos Transición Climática Mioceno. Su registro fósil ha sido estudiado durante casi siglo y ofrece una las mejores ventanas ecosistemas terrestres Neotrópico Neógeno. Hemos compilado todos estudios publicados y, utilizando correlación gráfica mapa...
Abstract Cenozoic sedimentary rocks of the intermontane Bagua Basin record Andean orogenic history northern Peru at ~4–7°S. The Peruvian Andes define termination Central and are comprised a narrow, low‐elevation orogen relative to rest Andes. New stratigraphic sedimentologic field observations, subsidence analysis, detrital zircon provenance analysis enable reconstruction regional tectonic history. Late Cretaceous Paleocene U‐Pb age spectra from Fundo El Triunfo Rentema formations reveal...
La localización en México del margen sur de Laurencia durante el Paleozoico ha sido centro intenso debate. Dichalocalización es necesaria para análisis la hipótesis actual consistente que fragmentos Norte América fueron transportadoshacia Sud ruptura (Cámbrico Temprano) y Pangea (Mesozóico Temprano), mientras queenormes movimientos laterales norte Mesozoico ocasionaban desplazamiento faja orogénica Ouachita.Tomando cuenta afloramientos Paleozoicos, datos isótopos plomo sismicidad gravimetría...
Detailed geologic mapping (639 field stations in ~700 km2) and a ~50 km-long gravity survey (142 stations) the western Azuero Peninsula revealed two faulted folded slivers of oceanic crust attached to trailing edge Caribbean Large Igneous Plateau (CLIP). Our new data, along with published geochronology, allowed us reconstruct Cretaceous forearc configuration CLIP prior seamount collision, ophiolite accretion, whole-margin deformation. The is composed tectonic arranged south-verging,...
Located in northern Peru, at the lowest segment of Central Andes, Bagua Basin contains a Campanian to Pleistocene sedimentary record that archives local paleoenvironmental and tectonic history. We present new δ18O δ13C signatures pedogenic carbonate nodules from paleosols Campanian–Maastrichtian Fundo El Triunfo Formation upper Eocene–middle Miocene Sambimera reconstruct isotopic composition paleo-meteoric water floristic biome. compare these results modern values newly obtained transect...
