New geochronological data [zircon U/Pb, titanite fission-track (TFT) and apatite fission-track (AFT) dating and apatite (U-Th-Sm)/He thermochronology] and thermal history modelling yield constraints on the development of the granitoid basement of the Kuznetsk-Alatau Mountains, southern Siberia. The final stages of magmatism in the Kuznetsk-Alatau palaeo-island-arc are Late Cambrian, and collision of the arc with Siberia occurred in the Early Ordovician. The basement was exhumed by the Early Devonian. Continuous Devonian-Early Triassic sedimentation filled the adjoining Kuznetsk and Minusa basins and buried (and re-heated) the Kuznetsk-Alatau basement. After initial Pangaea break-up and Siberian flood-basalt magmatism, the basement reached TFT and AFT retention-temperatures in the Middle Triassic and Early Cretaceous, respectively, during denudation-induced cooling

“…The uppermost sediments of the basin are mudstones, siltstones, and sandstones that contain only sparse and thin coal layers, and which belong to the Middle–Upper Permian Kolchugin Group (Kotel'nikov et al, ). In terms of composition and texture, the deposits of the Balakhon and Kolchugin groups in the Gorlovo Basin are similar to the same stratigraphic units in the Kuznetsk Basin (Davies, Allen, Buslov, & Safonova, ; De Grave et al, , and references therein). This Serpukhovian–Permian unit has a thickness of about 2,500 m, 1,150 m of which is represented by the Upper Carboniferous–Lower Permian Balakhon Group.…”

Tectonic history of the Kolyvan–Tomsk folded zone (KTFZ), Russia: Insight from zircon U/Pb geochronology and Nd isotopes

The Kolyvan–Tomsk folded zone (KTFZ) represents part of the Central Asian Orogenic Belt (CAOB). The KTFZ is mainly composed of detrital Late Palaeozoic sedimentary deposits, with minor intrusions. Detrital zircon geochronology on the Upper Devonian to Lower Permian sedimentary sequences of the KTFZ and the associated Gorlovo foreland basin yields four age peaks, reflecting the magmatic events in the source terranes. These events consist of (a) a minor Neoproterozoic peak (0.9–0.7 Ga), (b) a significant Early Palaeozoic peak (550–460 Ma), with a maximum at 500 Ma, and two well‐defined Late Palaeozoic peaks during (c) the Middle–Late Devonian (385–360 Ma) and (d) the Carboniferous–Early Permian (360–280 Ma), with a maximum at 320 Ma. Older zircons (>1 Ga) are quite rare in the sampled sedimentary sequences. Slightly negative εNd values and associated relatively young Nd model ages were obtained (εNd(T) = −0.78, T (DM) ~1.1 Ga for Upper Devonian sandstones, εNd(T) = −1.1, T (DM) ~1.1 Ga for Lower Permian sandstones), suggesting only minor contribution of ancient continental crust to the main sedimentary units of the KTFZ. All intrusive and volcaniclastic rocks on the contrary are characterized by high positive εNd(T) values in the range of 3.78–6.86 and a Late Precambrian model age (T (DM) = 581–916 Ma), which corroborates its juvenile nature and an important depleted mantle component in their source. The oldest unit of the KTFZ, the Bugotak volcanic complex formed at the Givetian–Early Frasnian transition, at about 380 Ma. Upper Devonian detrital deposits of the KTFZ were formed in the Early Palaeozoic accretion belt of the Siberian continent and specifically in a passive continental margin environment. Deposits of the Gorlovo foreland basin, adjoining the KTFZ, were accumulated as a result of erosion of the Carboniferous–Early Permian volcanic rocks, which are now buried under the Meso–Cenozoic sedimentary cover of the West Siberian Basin. The magmatic events, recorded in the KTFZ zircon data, correspond to the most significant magmatic stages that affected the western part of the CAOB as a whole.

“…Interpretación: Este elemento se considera originado a partir de eventos de inundación y se los interpreta como canales de desborde próximos a la red principal de canales como parte de abanicos de desborde (Davies-Vollum y Kraus, 2001) que resultan de la desaceleración luego de la expansión del flujo (Davies et al, 2010). Arquitecturas como la descrita que aparecen aisladas en la planicie de inundación y relacionadas con niveles con pedogénesis pueden asociarse a procesos de avulsión del canal principal que pueden ser eventualmente rellenadosles por cambios posdepositacionales por procesos pedogenéticos (Pye y Tsoar, 1990).…”

La evidencia de una alta energía de transporte y suministro de sedimento puede deducirse a partir del dominio de conglomerados y la preservación de dunas de gran escala (Davies et al, 2010).…”

RESUMEN.En el sector centro-este de la Cuenca Neuquina, suroeste de Neuquén, Patagonia Argentina, el Subgrupo Río Neuquén de origen continental ha sido dividido en dos secuencias estratigráficas incompletas (SI y SII) sobre la base de discontinuidades que limitan arreglos de litofacies y elementos arquitecturales característicos. Parte de la sucesión (Formación Portezuelo-SI) se formó a partir de sistemas fluviales de baja y alta sinuosidad que drenaban hacia el noreste. La acreción lateral y oblicua es un rasgo importante de los sistemas de alta energía con carga mixta. Los depósitos de planicie de inundación dominan la estratigrafía, contribuyendo con más del 45% de los sedimentos. La Formación Plottier (SII) se acumuló a partir de un sistema de baja sinuosidad perenne con un buen desarrollo de los depósitos de planicie aluvial con eventos de inundaciones. La unidad se acumuló sobre una topografía con un gradiente general hacia el este-noreste. La arquitectura aluvial y patrones de apilamiento en el Subgrupo Río Neuquén estuvo controlada por la combinación de factores alogénicos, el más significativo fue la tectónica seguida por el clima. La sucesión del Cretácico Tardío en la cuenca de antepaís andina, depositada en la cuenca periférica, consiste de ciclos tectónicos que comprenden dos componentes: estratos depositados en una cuenca subalimentada (Formación Portezuelo, AA-SI) y sedimentación en una cuenca sobrealimentada sin un abultamiento periférico definido topográficamente (Formación Plottier, BA-SII). ABSTRACT. Sedimentology and high resolution stratigraphy of Río Neuquén Subgroup (Upper Cretaceous) department Confluence, Province of Neuquén, Argentina.The Upper Cretaceous exposid in the northeastern part of the Neuquén Basin, southeast of Neuquén, Argentina. Río Neuquén Subgroup of continental origin, has been divided into two incomplete stratigraphic sequence units (SI y SII) on the basis of lithofacies assemblages and architectural elements. Parts of the succession (Portezuelo Formation SI) formed in northeasward-draining low and high sinuosity fluvial systems. Those are analyzed in detail in terms of macroform-scale and stratigraphic-level architecture to assess fluvial styles and the evolution of non-marine depositional environments. Lateral and oblique accretion is a significant process of deposition in high-energy systems with mixed load. The overbank deposits dominate the floodplain stratigraphy; they contribute more than 45% of floodplain sediments. The Plottier Formation (SII) was accumulated from a low sinuosity perennial system with well developed deposits of alluvial plain with flood events. The unit was accumulated on topographic slopes dipping from west-southwest to east-northeast. The alluvial architecture and stacking patterns in the Río Neuquén Subgroup were controlled by a combination of allogenic factors, most significantly tectonics followed by climate. The Upper Cretaceous succession in the Andean foreland basin, deposited in a backbulge zone, consists of tectonically-driven cycles ...
