Abstract
Abstract The Paleozoic tectonic framework of the eastern Hexi Corridor Belt is ambiguous. However, thick Paleozoic sediments from the eastern Hexi Corridor Belt can provide clues to this problem. In this paper, we deal with the detrital zircon provenance of Middle Ordovician to Late Devonian strata using LA-ICP-MS U–Pb dating, documenting the temporal and spatial changes of provenance. Detrital zircon U–Pb ages indicate that the primary provenance was the Qilian Orogenic Belt and the Alxa Block. However, two samples from Late Devonian strata show different provenance characteristics, from the North Qilian Orogenic Belt, and the Alxa Block and the North China Block, respectively. Different age distributions through time reflect provenance changes due to continuous convergence of the Central Qilian Block and the Alxa Block from the Middle Ordovician to Late Devonian. A significant age cluster ranging from 2000 to 1800 Ma, which is a detrital zircon signature of the North China Block, appeared in the Late Devonian Zhongning Formation. Our preferred interpretation is that the amalgamation of the Alxa Block and the North China Block likely occurred at that time. Moreover, similar Paleozoic fossils, paleolatitudes and detrital zircon distribution indicate that the Hexi Corridor Belt has an affinity to eastern Gondwana.

Abstract Detrital zircon LA-ICP-MS U–Pb ages of the Paleozoic strata in the southeastern Alxa Block indicate that the primary provenance did not change between the Devonian and the Early Carboniferous. Except for a sample from the Cambrian strata, the Early Paleozoic North Qilian Orogenic Belt may have been a major source of Paleozoic sediments in the study area. The main source of Lower–Middle Devonian sediments was the Early Paleozoic North Qilian Orogenic Belt. The source of the Upper Devonia...

Abstract Lithofacies and faunal assemblage affinities of the Helan Mountains and its adjacent blocks are explored using field investigations and analysis of previous results. The tectonic affinity between the Alxa Block and the North China Block is analyzed by means of LA-ICP-MS detrital U–Pb zircon age spectrums. The Early Paleozoic stratigraphic framework is constructed and stratigraphic contact relationships between the study area and its adjacent regions are assessed. The ocean–continent con...

Abstract SHRIMP U–Pb detrital zircon geochronology and depleted-mantle Nd-model ages of clastic rocks were combined to understand the sediment provenance in the Neoproterozoic Sergipano Belt. The Sergipano is the main orogenic belt between the Borborema province and the Sao Francisco Craton, eastern South America; it is divisible into several lithostratigraphic domains from North to South: Caninde, Poco Redondo-Maranco, Macurure, Vaza Barris, and Estância. Nd model ages (TDM) and detrital zircon...

Abstract The detrital zircon ages of the Early Paleozoic Xiangshan Group in the southeastern Alxa Terrane show that the lower age limit for the Xiangshan group is 512 Ma. The Xiangshan Group is older than the Middle Ordovician strata in the study region and is the Middle–Late Cambrian in age, which is the same age as the fossils found in it. The detrital zircon ages record the Grenville and Pan-African Orogenic Events, and the major age peaks are 963 Ma, 1179 Ma, 551 Ma and 2517 Ma. The North Ch...

Abstract The relationship between the Alashan Terrane and North China is a contentious issue given the discovery of allochthonous detrital zircons in Middle Ordovician flysch sandstones from the southwestern Ordos Margin and the large differences in palaeolatitudes between the North China and Tarim cratons. We have collected a suite of Middle to Late Devonian sedimentary rocks from the Niushoushan Mountains at the southeastern margin of the Alashan Terrane, adjacent to the western margin of the ...

Abstract An integrated study of borehole data and outcrop of Mississippian (late Tournaisian to late Visean) rocks in Co. (County) Galway, western Ireland has enabled a more detailed geological map and lithostratigraphy to be constructed for the region. Several carbonate formations have been distinguished by microfacies analysis and their precise ages established by micropalaeontological investigations using foraminifers and calcareous algae. In addition, palaeogeographic maps have been construc...

Abstract Since the Cenozoic, the Tian Shan is rejuvenated by crustal shortening related to the ongoing India–Asia collision. However, the tectonic process prior to the Cenozoic remains ambiguous, especially in the Bogda area of the eastern Tian Shan. The continuous Late Paleozoic–Mesozoic sequences in the Bogda area record abundant information about the basin–mountain interaction. U–Pb (LA–ICP-MS) dating of detrital zircons from seven sandstone samples from Permian to Jurassic was used to invest...

Abstract Oligocene–Miocene strata in the Subei and Xiaobiegai basins of the Subei area, located in the eastern Altyn Tagh fault (ATF), northern Tibetan Plateau, record important characteristics of the ATF evolution. Detrital zircons laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) U–Pb ages from two samples, together with paleocurrent directions and clastic composition in the Xishuigou section demonstrate that sediments in the Subei basin originated from the Danghenanshan ...

The Xiaoliugou W-Mo deposit in Gansu is a porphyry-skarn-quartz type deposit related to granitoids. Xiaoliugou granitoids are comprised of monzogranite and granodiorite. In this paper,zircon U-Pb dating and geochemistry of the Xiaoliugou granite are studied to constrain its geochronology and petrogenesis. Zircon LA-ICP-MS dating yields concordant ages of 454. 0 ± 2. 0 and 417. 7 ± 1. 7Ma respectively indicating that the two plutons were formed at Caledonian,later affected by Hercynian and Yansha...

[1] Cambrian sedimentary rocks in the southern part of the South China Craton were derived from a source that lay to the south or southeast, beyond the current limits of the craton and which is no longer preserved nearby. U-Pb ages and Hf isotope data on detrital zircons from the Cambrian sequence define two distinctive age peaks at 1120 Ma and 960 Ma, with eHf(t) values for each group identical to the coeval detrital zircons from Western Australia and the Tethyan Himalaya zone, respectively. Th...

The petrogenesis and geodynamic implications of the early Paleozoic magmatic events in the eastern Hexi Corridor Belt, NW China, remain poorly constrained. In this study, we present high-quality zircon U–Pb ages as well as geochemical and zircon Lu–Hf isotopic data for three early Paleozoic intrusive rocks from the Mafuxiazi area in the eastern Hexi Corridor Belt. The LA-ICP-MS U–Pb dating results suggest that there are two stages of magmatic activities during the late Ordovician (447 Ma) and la...
