摘要:... The detrital zircon U-Pb depositional ages acquired for the three intercalated sedimentary units do not provide any such evidence of significantly prolonged magmatism in the Dongargarh Supergroup.(#br)The close proximity between the depositional ages and the similarities be...

摘要:... Zircon U-Pb ages show Carboniferous ages (325 ± 3 Ma) for the formation of this granitoid. The granitoid is mostly metaluminous, ferroan and alkalic monzonite to monzodiorite. These rocks have high ratios of FeO T /MgO, Ga/Al, high concentrations of K 2 O + Na 2 O, low a...

摘要:... Based on detrital zircon U-Pb dating of the Suining Formation sandstone from the Daba Mountains, the upper limit of the deposition of the Suining Formation is given by the detrital zircon U-Pb ages. The youngest detrital zircon U-Pb age is ∼120 Ma, which reflects a deposi...

摘要:Abstract(#br)Zircon U-Pb geochronology and heavy minerals are used in combination to provide valuable insights into the provenance of the early Eocene Jianghan Basin, central China. Five samples for zircon U-Pb dating and eighty-five samples for heavy mineral analysis were c...

摘要:... We report new whole-rock elemental and Nd isotope data along with zircon U-Pb ages on these granites. The ID-TIMS zircon U-Pb ages of these granites are 1645 ± 25 Ma, 1695 ± 9 Ma, and 1796 ± 17 Ma. These granites are metaluminous to weakly peraluminous, alkali-calcic to...

摘要:Abstract(#br)New insights in the Mesozoic geodynamic evolution and related basin-range interactions in the Kyrgyz Tien Shan were obtained based on new sedimentological and detrital zircon U-Pb (LA-ICP-MS) results from Jurassic to Paleogene sedimentary sequences. Studied sedime...

摘要:Abstract(#br)This study uses apatite fission track (AFT) and zircon U-Pb data to reveal the cooling history of bedrocks from the Dong'an, Cuihongshan and Pingdingshan deposits in the Lesser Hinggan Range, which is one of the most important metallogenic districts in NE China. A...

摘要:... In order to put more constraints on the Precambrian basement composition and crustal evolution of the Central Tianshan Block, we conducted field structural investigations and zircon U-Pb dating on the meta-sedimentary and meta-igneous rocks along the Wulasitai – Wulanmor...

摘要:... An integrated study of detrital zircon Lu-Hf isotopes and U-Pb ages from two sandstones in the Huashan Group together with previous studies reveals six major tectonothermal events in the EYB occurring at about 2.87 Ga, 2.67 Ga, 2.5 Ga, 2.0 Ga, 1.84 Ga and 0.8 Ga. Combined...
