The detrital zircon populations of the Algarve Triassic sandstone are very different from those of the lower–upper Carboniferous Mértola and Mira formations (South Portuguese Zone), upper Devonian – lower Carboniferous Horta da Torre, Represa and Santa Iria formations (Pulo do Lobo Zone), and the late Carboniferous Santa Susana and early Permian Viar basins, which are ruled out as potential sources.

Our new detrital zircon U–Pb ages from 24 sandstone samples from the Cambrian to Permian succession of Saudi Arabia provide new insights into these topics. Five main zircon age populations have been identified in varying amounts, with age peaks at 625 Ma, 775 Ma, 980 Ma, 1840 Ma and 2480 Ma.

2021-9-3 · The material that holds the greatest insight into these fundamental questions, because it can contain a record of some of the earliest history of the Earth, is a mineral named zircon. For example, a few grains of zircon found in the early 1990s in a sandstone from western Australia dates back 4.2–4.3 billion years, and we know from meteorites ...

2020-10-9 · Zircon is a common accessory mineral in clastic sediments, which retains U–Pb isotopic signatures during erosion, recycling, and transport; differences in zircon age populations in sediments are linked to the nature and age of source terranes (Ji et al. 2019; Joy et al. 2019; Liu et al. 2019; Chaudhuri et al. 2020).Hence, detrital zircon U–Pb age geochronology is reliable to infer ...

Zircons in the sandstone samples (XDG, ZYC, XWK, JT3, STC, and S336) taken from the southern part of the NCC do not contain zircons of ca. 310 Ma, but all have a prominent peak at ca. 450 Ma.

2020-9-23 · In contrast, sedimentary sequences dominated by sandstone could well yield abundant > 60 µ m zircon grains that predate deposition, thereby diluting syn-depositional-age zircon grains. Future attempts to determine depositional ages from fluvial strata should accordingly focus on sequences dominated by fine-grained strata, rather than ...

This study presents initial U-Pb detrital zircon geochronology results coupled with sandstone provenance point-counting to constrain sedimentary basin evolution along the East Gobi Fault Zone (EGFZ), southeastern Mongolia. These results fingerprint potential piercing points in sedimentary units argued here to have once been part of the same depositional basins, now offset by the strike-slip ...

2018-5-18 · Detrital zircon SHRIMP U-Pb geochronology data from a meta-arkosic sandstone (SN-1) and an iron formation (SN-2) show mainly two age groups of ca. 2.5 Ga and ca. 1.9–1.75 Ga. This together with intrusion age of the granite gneiss (ca. 1.70–1.65 Ga) clearly indicate that the iron formations were deposited during the Upper Paleoproterozoic.
