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:Abstract(#br)Zircon U–Pb dating using LA-ICP-MS was applied to six Quaternary tephras in Boso Peninsula, central Japan: J1, Ks4, Ks5, Ks10, Ks11, and Ch2 in descending order. Accurate age determination of these tephras is of critical importance because they are widespread tep...

摘要:... SIMS zircon U–Pb dating shows: igneous zircons from the biotite plagioclase-gneiss and hornblende plagioclase-gneiss have U–Pb ages of 2535 ± 8 Ma and 2543 ± 14 Ma, respectively; zircons from the biotite-leptynite have an age of 2537 ± 13 Ma. We infer that the ages ...

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:... 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:... 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:... 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:... Zircon U–Pb dating of gabbroic and quartz diorites yielded weighted mean 206Pb/238Pb ages of 263.5 ± 5.1 Ma ( N = 12, mean squared weighted deviation (MSWD) = 0.78, probability = 0.66) and 262.0 ± 5.6 Ma ( N = 10, MSWD = 0.50, probability = 0.87), r...

摘要:... Detailed U–Pb dating of zircon from the meta-volcanic rocks and meta-sedimentary rocks of the Precambrian Langshan group shows that the Langshan Group formed in the Neoproterozoic. The evidence includes the zircon age of 804.1 ± 3.5 Ma for the meta-volcanic rocks and ...

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...
