“…A local sediment source is supported by the observation of large granitic clasts and boulders in the diamictite at the base of the glacial strata; these are interpreted to have originated from corestones within local weathering profi les (Socha et al, 2006). Petrographic studies on the Carboniferous strata deposited near Malanzan also support a local source region from the Famatinian belt (Net and Limarino, 2006).…”

In this study, we utilize multiple thermochronometric methods, including apatite and zircon fi ssion track, (U-Th)/He, and zircon U-Pb, to evaluate the cooling history and provenance of sedimentary strata of the late Carboniferous to Late Permian eastern Paganzo basin and adjacent basement rocks (Argentina). The strata in the study area represent a long-lived, composite basin system that is interpreted to have experienced multiple periods of deformation, and to have received sediment from a number of different source terranes. These strata are well exposed in the Sierra de Chepes of west-central Argentina. New thermochronometric data and fi eld observations, together with published data from the surrounding mountains, allow us to reconstruct: (1) the cooling history of the underlying basement rocks and the highlands surrounding the basin, (2) the thermal history of the source areas that provided sediment to the basin, and (3) the timing of structural inversion of the basin. Our data suggest that parts of the Sierra de Chepes were rapidly exhumed in Late Devonian-Carboniferous times; these exhuming areas supplied sediment to the adjacent basin. In contrast, the overlying red-bed strata originated from a slowly exhuming region located farther east or north of the basin within the Pampean orogenic belt or the Famatinian belt, respectively. Burial by latest Carboniferous and younger strata and an elevated geothermal gradient resulted in heating of the underlying Upper Carboniferous strata and underlying granitoid basement to temperatures between 80 °C and 140 °C. During Triassic time, the eastern Paganzo basin was structurally inverted; this event was marked by rapid cooling and may be related to regional extension and the development of rift basins to the west. The basement and the Upper Paleozoic strata of the eastern Paganzo basin in the study area have remained below 50 °C since latest Jurassic-Early Cretaceous times and are characterized by very slow cooling. Results of this study provide a thermochronometric view along an ~330 m.y. path defi ning the geologic evolution of the eastern Paganzo basin and the upper crust of west-central Argentina.

“…The following illumination should be noticed. (a) The content of feldspar in the samples from the study area is commonly low, especially the ones of Cycle V. (b) Though four petrofacies were identified from the samples, more or less differences exist between the contents of three main clasts in the studied sandstones and the standards defined by Net and Limarino (2006). Thus, the availability of sandstone petrofacies here needs to be conformed further.…”

“…The plots on Qp-Lv-Ls diagram are divergent, showing that most of the sandstones from Wuchang Formation fall within or near the field of collisional orogen, with minority in subduction complex sources and the majority of the samples from Huajiahu Formation plot in or near the fields of collision orogen sources and subduction complex sources, with the trend of transition to the field of arc orogen sources. Net and Limarino (2006) researched the detrital composition and petrofacies of sandstones from Paganzo basin, Northwest Argentina, and seven petrofacies were built, as demonstrated in Table 2. In the same way, four petrofacies, QF, QF-Ls, QL, and QLv, were distinguished from 117 samples.…”

The detrital modes of the sandstones from the south basin of Dabie (大别) orogenic belt during the Early-Middle Jurassic are complex due to multiple supplying. Detrital compositions of medium-coarse sandstones from the Lower-Middle Jurassic, Huangshi (黄石), show three main provenances: recycled ororgen, volcanic arc (arc orogen), and continental block on the bases of the Dickinson discriminating diagrams of modal composition and analysis of sandstone petrofacies. Combined with sparse published paleocurrent data, geotectonic setting of the study area, and the unpublished detrital zircon age data, the positions of the main provenances are inferred as follows: coastal orogenic belt (COB) in the East China provided detritus as the recycled orogen provenance; Dabie orogenic belt (DOB) to the north was the source of volcanic arc (arc orogen) materials; and the continental block clasts were likely from the uplift of the Yangtze basement (UYB) (Jiangnan (江南) uplift). Six sedimentary cycles are recognized in the studied section, one in Wuchang (武昌) Formation, and five in Huajiahu (花家湖) Formation. During the deposition, the three main provenances play different roles. The quantitative petrofacies analysis revealed distinct changes of the effect from each source, that is, 61.9% (Cycle I)→54.5% (Cycle III)→50% (Cycle IV)→57.9% (Cycle V)→14.3% (Cycle VI), 14.3% (Cycle I)→21.2%( Cycle III)→40% (Cycle IV)→36.8% (Cycle V)→14.3% (Cycle VI), and 23.8% (Cycle I)→24.2% (Cycle III)→10% (Cycle IV)→5.3% (Cycle V)→71.4% (Cycle VI) from COB, DOB, and UYB, respectively. The results show that (1) COB behaved in considerable activation during the Early Jurassic but weakened in the Middle Jurassic; (2) the vigorous tectonic uplift of DOB initiated in Middle Jurassic; and (3) UYB was in stabilization basically from the Early to Middle Jurassic.

“…Las reconstrucciones paleogeográficas indican que la zona en estudio se encontraba próxima a un arco positivo, constituido principalmente por rocas devónicas, del Mississippiano y Paleozoico inferior, conocido como Protoprecordillera. Este alto topopográfico separó a la cuenca Paganzo (mayormente continental durante el Pérmico) de la de río Blanco (principalmente marina) y si bien su relieve parece haber disminuido significativamente hacia el Guadalupiano (net & Limarino, 2006;Isbell et al, 2012), evidentemente la erosión de las rocas devónicas fue la que ha proporcionado la mayor parte de los elementos retrabajados.…”
