摘要:Abstract(#br)We have developed a new analytical technique for precise and accurate in situ Hf isotope ratio measurements for zircons by means of laser ablation-multiple collector-inductively coupled plasma mass spectrometry (LA-MC-ICPMS). Newly designed sample cell and N 2 mi...

摘要:... We present the first Hf isotope determinations for the Jijal Complex, made on rutile from garnet gabbros. These lithologies are zircon-free, but contain rutile that formed as an early phase. Recent developments in analytical capabilities coupled with a careful analytical...

摘要:Abstract(#br)Zircon Hf isotope composition is widely used to trace the growth and evolution of continental crust. However, it is controversial whether the Hf isotope composition of magmatic zircons can faithfully reflect that of their sources, especially for S-type granites....

摘要:Abstract(#br)The 176 Lu– 176 Hf radioactive decay system has been widely used to study planetary crust–mantle differentiation. Of considerable utility in this regard is zircon, a resistant mineral that can be precisely dated by the U–Pb chronometer and record its initial Hf isotope...

摘要:... 578–588 Ma) are marked by similar Hf isotope compositions and REE patterns to those of inherited cores (ca. 825–600 Ma), indicating that these aspects of the chemical signature of the magmatic zircons have likely been inherited from the source. The U–Pb ages and initia...

摘要:Abstract(#br)This study systematically investigated the Lu–Hf isotope signatures of zircons in jadeitite from the North Myanmar, which was formed from jadeite-forming hydrothermal fluids and is always sourced in serpentinite as a mark for the subduction zone. Results show t...

摘要:Abstract(#br)Zircon is an important accessory mineral for studying the crust-mantle interaction and crustal growth through time because zircon crystals not only allow precise dating but also record initial Hf isotope ratios of the host magma. Our study on a suite of gabbronorite,...

摘要:Abstract(#br)To constrain the paleoposition of Indochina within Gondwana during the Early Paleozoic, we performed in-situ U–Pb and Hf isotope analyses on detrital zircons from three river sediment samples in the Truong Son Belt of the Indochina block. The age distributions yi...

摘要:... Their respective element compositional and Lu–Hf isotopic features were studied using LA–(MC)–ICP–MS methods, showing that the compositions of the pre-magmatic core domains are intensely modified by hydrothermal processes, exhibiting no differences with hydrother...

摘要:... To elucidate the controlling factors of porphyry-epithermal mineralization in West Java, we analyzed the Hf isotopies of zircons from the igneous rocks and in situ Pb isotopes of sulfides (galena, pyrite, arsenopyrite) in the Ciemas deposit. The results show that the zircons...
