We introduce and propose zircon M257 as a future reference material for the determination of U‐Pb ages by means secondary ion mass spectrometry. This light brownish, flawless, cut gemstone specimen from Sri Lanka weighed 5.14 g (25.7 carats). Zircon has TIMS‐determined, mean isotopic ratios (2s uncertainties) 0.09100 ± 0.00003 206 pb/ 238 U 0.7392 0.0003 207 235 U. Its age is 561.3 0.3 Ma (unweighted mean, uncertainty quoted at 95% confidence level); system concordant within decay constants....
Abstract The north Qilian high‐pressure (HP)/low‐temperature (LT) metamorphic belt is composed mainly of blueschists, eclogites and greenschist facies rocks. It formed within an Early Palaeozoic accretionary wedge associated with the subduction oceanic crust considered to be one best preserved HP/LT belts in China. Here we report new lawsonite‐bearing eclogitic rocks enclosed epidote blueschists North Mountains. Five samples contain unaltered lawsonite coexisting omphacite phengite as...
Abstract The Central Orogenic Belt (COB) of China is a major continental collision zone that contains extensive outcrops deeply subducted and exhumed rocks at both the eastern western end belt. Here we report discovery microdiamonds from eclogites felsic gneisses in North Qinling central portion COB. This demonstrates country affinity shared ultra‐high‐pressure metamorphic (UHPM) event provides bridge connecting two previously recognized UHPM terranes, thereby establishing existence belt...
We report SHRIMP U‐Pb, rare earth element, Hf isotope, and laser Raman spectroscopic data on zircons from ultrahigh‐temperature (UHT) granulites the Jining Complex of Khondalite Belt in Western Block North China Craton (NCC). These UHT rocks form part an ultrahot orogen that formed along collisional margin NCC associated with tectonics assembly Paleoproterozoic supercontinent Columbia. Despite core‐rim textures displayed by some zircons, their age values sharply converge within error,...
Abstract High-grade pelitic metasedimentary rocks (khondalites) are widely distributed in the northwestern part of North China Craton and were named ‘Khondalite Belt’. Prior to application zircon geochronology, a stratigraphic division supracrustal into several groups was established using interpretative field geology. We report here SHRIMP U–Pb ages Hf-isotope data on metamorphosed sedimentary magmatic at Daqingshan, typical area Khondalite Belt. The main conclusions as follows: (1) early...
Thirty-seven granitoids from Scotland have been dated using the sensitive high-resolution ion microprobe zircon method. Granitoids were intruded during: (1) crustal stretching at c . 600 Ma after Rodinia broke up (A-types); (2) Grampian event of thickening when Midland Valley Arc terrane collided with Laurentia 470 (S-types); (3) erosion and decompression over-thickened Laurentian margin 455 (4) subduction Iapetus Ocean lithosphere under starting 430 (I-types); (5) roll-back beginning 420...
