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 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 The Qilian Orogen at the northern margin of the Tibetan Plateau is a type suture zone that recorded a complete history from continental breakup to ocean basin evolution, and to the ultimate continental collision in the time period from the Neoproterozoic to the Paleozoic. The Qilian Ocean, often interpreted as representing the “Proto-Tethyan Ocean”, may actually be an eastern branch of the worldwide “Iapetus Ocean” between the two continents of Baltica and Laurentia, opened at ≥ 710 Ma ...

The Upper Ordovician-Devonian strata are distributed asymmetrically in the North Qilian orogenic belt(NQOB)and are record of the collision process between Central Qilian block and North China plate.Age spectra of detrital zircons from the Upper Ordovician strata in the eastern of belt suggest that sediments in the basement of Upper Ordovician originate from the North Qilian arc and detritus in the upper part of Ordovician come from Central Qilian block and the North Qilian arc to the South and N...

A suite of low-grade metamorphic sedimentary rocks,exposed in Huashikoujing area of eastern Longshoushan,was originally regarded as the Paleoproterozoic "Longshoushan Group".Detrital zircons from two low-grade metamorphic sedimentary rocks yielded ages ranging from 0.52 Ga to 3.56 Ga,similar to the age spectrum of the rock from neighboring Cambrian Dahuangshan Group.Thus,the metamorphic sedimentary rocks were probably deposited in the middle-late Cambrian period.A total of 129 concordant data we...

Sandstone is the direct record of mountain uplift in the basin,and its detrital components have a good effect in analyzing orogenic belts and tectonic setting of sedimentary provenances.Jurassic sediments were systematically investigated with four main methods,i.e.,features comparison in detrital components,vertical evolution characteristics of detrital components in single well,Dickinson chart and evolution characteristics between Q/(F+L) and F/L of component maturity.Some conclusions have been...

The Alxa Block is considered part of the North China Craton, but the unambiguous Archean basement has not been reported. In this study, we present the first evidence of the Neoarchean rocks in the Beidashan area of the western Alxa Block. The petrographic and geochemical data show that these rocks are granodiorite with TTG (tonalite-trondhjemite-granodiorite) characteristics. Zircon U-Pb dating gave an age of 2522±30 Ma for the magmatic core and 2496±11 Ma for the metamorphic recrystallized rim....
