摘要:... SHRIMP and LA–ICP–MS zircon U–Pb dating results imply that these granites were emplaced at 435 ± 4 Ma, 427 ± 3 Ma, 417 ± 6 Ma, 404 ± 6 Ma and 382 ± 2 Ma, respectively. The ages gradually decreased from the southeast to the northwest, implying that the MYB was incr...

摘要:... Here we report the zircon U–Pb age and Hf isotopes, geochemical characteristics and Sr–Nd–Pb isotopic data of the alkali mafic dikes, and diorite, aegirine–nepheline syenite and syenite porphyry units in the Wajilitag intrusive complex. Zircons from the diorite and a...

摘要:... Based on various petrological and geochemical investigations performed from south to north across the Lincang granite, a new set of data, which includes zircon chronological and Hf isotopic data, is presented to discuss the origin of the Lincang granite and its tectonic sig...

摘要:... This paper presents new results from phase equilibrium modelling and SHRIMP zircon U–Pb dating on the MP garnet-sillimanite granulites, in order to better understand the relationship between the MP and HP pelitic granulites, the tectonic implications of the MP pelitic ...

摘要:... To constrain the formation age of the arc lower-crust, U–Pb zircon dating was applied to mafic enclaves in tonalites of the Tanzawa Tonalitic Pluton (TTP), which is regarded as the exposed middle crust of the former Izu–Bonin–Mariana arc, using a laser ablation-induct...

摘要:... LA-ICP-MS zircon U–Pb dating provided weighted mean 206 Pb/ 238 U ages of 743.0 ± 2.5 Ma for the No.I granite (G1) and 739.0 ± 3.5 Ma for the No.II granite (G2). A clear core-rim texture of similar age and a high zircon saturation temperature of ca. 849 ± 14 °C were ob...

摘要:... This paper conducted zircon dating of metamorphic rocks from the Xiaoqinling area. The results demonstrate that the collision between the Western and Eastern Blocks occurred in the Paleoproterozoic. Laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) zircon...

摘要:... SHRIMP U–Pb dating of zircons from the jadeitite yielded a concordant weighted mean 206 Pb/ 238 U age of 404 ± 7 Ma, which we interpret as the age of peridotite serpentinization and jadeitite formation in the suprasubduction zone mantle. This age indicates that subducti...

摘要:... The Shuikoushan Pb–Zn–Au orefield is a typical example located in Hunan Province. This study reports LA-ICP-MS zircon U–Pb ages, whole-rock chemistry, and Sr–Nd–Pb isotopic compositions, and in situ Hf isotopic geochemistry of zircons from the Laomengshan rhyodac...

摘要:... We have applied petrology, whole-rock geochemistry and Sr–Nd isotope, zircon U–Pb geochronology, trace element composition and Lu–Hf isotope of these granitic leucosomes to determine the nature and timing of partial melting of these rocks. Anatexis of the felsic gne...
