摘要:... Whether the zircon cores are inherited from the source of the granitoids or just occasionally captured from the wallrocks during magma ascent is highly controversial. In this paper, three Mesozoic granites with diverse ages and geochemical compositions but uniformly ~1.8 Ga zircon...

摘要:Abstract(#br)Zircon is a powerful tool to study the internal evolution of igneous bodies and their interactions with country rocks. At pluton borders, zircon may record the emplacement history from the crystallization onset to deuteric processes, as well as inheritance from co...

摘要:Abstract(#br)Laser depth profiling of laboratory-induced helium diffusion profiles in natural zircon confirms that helium diffusivity is crystallographically controlled and significantly anisotropic. Experiments on Mud Tank zircon with low degrees of alpha radiation damage (...

摘要:Abstract(#br)Recent research has demonstrated the importance of understanding alpha radiation damage in zircon in order to effectively interpret the thermochronologic significance of (U-Th)/He dates and to appropriately select laser ablation U/Pb reference standards. Direct ...

摘要:Abstract(#br)Hydrothermal zircon grains have trace element characteristics such as low Th/U, high U, and high rare earth element (REE) concentrations that distinguish them from magmatic, metamorphic, and altered zircon grains, but it is unclear whether these characteristics res...

摘要:Abstract(#br)This study documents the strain accommodation mechanisms in zircon under amphibolite-facies metamorphic conditions in simple shear. Microstructural data from undeformed, fractured and crystal-plastically deformed zircon crystals are described in the context of the...

摘要:... This contribution is an integrated study of petrology, zircon and titanite U-Pb ages, as well as zircon Hf-O and major minerals O isotope compositions for a felsic vein and its host granitic gneiss in the Sulu UHP terrane to decipher the timing and mechanism of partial mel...

摘要:Abstract(#br)A method to prepare amorphous silica particles from zircon has been developed using the fluorination method through a three-step process: the fluorination of zircon using ammonium bifluoride at 230 ℃, the sublimation of (NH 4 ) 2 SiF 6 at 300 ℃ and the hydrol...

摘要:... To test the utility of detrital zircon U Pb geochronology for determining soil provenance, and to determine the provenance of soils in Middle Tennessee, samples of soil and underlying bedrock were collected from two sites, along with alluvium from a nearby river and loess fro...

摘要:Abstract(#br)U-Pb geochronology of Quaternary zircon crystals is challenging due to their low levels of radiogenic-Pb, the importance of accurate common-Pb correction, and the potential need for secular disequilibrium correction. (U-Th)/He dating offers an independent benchmar...
