The northwest Argentine Andes constitute a premier natural laboratory to assess the complex interactions between isolated uplifts, orographic precipitation gradients, and related erosion sedimentation patterns. Here we present new stratigraphic observations age information from intermontane basin sediments elucidate Neogene Quaternary shortening history associated sediment dynamics of broken Salta foreland. This part Andean orogen, which comprises an array basement‐cored range is located at...
Rainfall in the central Andes associated with South American Monsoon and Low-Level Jet results from orographic effects on atmospheric circulation exerted by Andean Plateau Eastern Cordillera. However, despite its importance for climate, no reliable records exist that allow decoding evolution of thresholds interactions between topography circulation, especially regarding onset humid conditions inherently dry southern Andes. Here, we employ multi-proxy isotope data lipid biomarkers, pedogenic...
Abstract The intermontane Quebrada de Humahuaca Basin (Humahuaca Basin) in the Eastern Cordillera of southern Central Andes NW Argentina (23°–24°S) records evolution a formerly contiguous foreland‐basin setting to an depositional environment during late stages Cenozoic Andean mountain building. This basin has been and continues be subject shortening surface uplift, which resulted establishment orographic barrier for easterly sourced moisture‐bearing winds along its eastern margin, followed...

ABSTRACT Sedimentary basins in the distal Cenozoic Andean retroarc yield an important geological archive that provides crucial insights into tectonic and sedimentary processes associated with different stages of mountain building. At 33° S, have operated during Neogene Quaternary periods orogenesis are well documented, whereas information on Paleogene period remains fragmentary partly enigmatic. The sedimentation at this latitude is represented by Divisadero Largo Formation, a 70‐m‐thick...
Abstract The Gofa Province and Chew Bahir Basin in the Broadly Rifted Zone (BRZ) between southern Main Ethiopian Rift (sMER) northern Kenya (nKR) record early volcanism associated faulting East Africa; however, spatiotemporal relationships remain poorly constrained. We applied apatite (U‐Th)/He (AHe) zircon (ZHe) thermochronometry to Neoproterozoic basement rocks from exhumed footwall blocks of extensional Basin, analyzed our result context well‐dated regional volcanic units BRZ unravel...

Abstract The Andean Plateau of NW Argentina is a prominent example high‐elevation orogenic plateau characterized by internal drainage, arid to hyper‐arid climatic conditions and compressional basin‐and‐range morphology comprising thick sedimentary basins. However, the development as geomorphic entity not well understood. Enhanced orographic rainout along eastern, windward flank causes reduced fluvial run‐off thus subdued surface‐process rates in hinterland. Despite this, many Puna basins...
Abstract The structural and topographic evolution of orogenic plateaus is an important research topic because its impact on atmospheric circulation patterns, the amount distribution rainfall, resulting changes in surface processes. Puna region north‐western Argentina (between 13°S 27°S) part Andean Plateau, which world's second largest plateau. In order to investigate deformational events responsible for initial growth this plateau, we carried out stratigraphic investigations within...
Abstract The Andean Plateau of north‐western Argentina (Puna) at a mean elevation ca. 4.2 km constitutes the southern continuation Altiplano; it is compressional basin‐and‐range province comprising fault‐bounded, high‐elevation mountain ranges and largely internally drained basins with often thick sedimentary volcaniclastic fill. Growing sedimentological structural evidence supports notion that Argentine Andes between 22° 26°S developed from an initial extensive broken‐foreland system...

Abstract Foreland basins are sensitive recorders of spatiotemporal variations in tectonic and climatic forcing associated with an approaching orogenic front. Thus, analysis foreland deposits their deformation patterns provenance signals allows assessment sedimentary processes during orogeny, providing clues to past environmental conditions. The Calchaquí region the southern part northwest Argentinian Eastern Cordillera (ca. 25–26°S lat) structurally evolved from a contiguous Paleogene Andes...

Abstract The thick‐skinned fold‐and‐thrust belt on the eastern flank of Andean Plateau in northwestern Argentina (NWA) is a zone active contractional deformation characterized by fault‐bounded mountain ranges with no systematic spatiotemporal pattern tectonic activity. In contrast, thin‐skinned Subandean northern and southern Bolivia primarily in‐sequence (i.e., west to east) fault progression, narrow Quaternary focused at front orogenic wedge. To better understand how recent accommodated...
Abstract Compared to the thin‐skinned Subandean foreland fold‐and‐thrust belt of northern Argentina and Bolivia, tectonically active morphotectonic province Santa Bárbara System in Andean broken northwestern is characterized by a temporally spatially disparate deformation style. Although there no well‐defined orogenic front associated with uplift these basement‐cored, reverse‐fault bounded mountain ranges, has been an overall eastward trend compressional since Miocene. While reactivation...
