“…Therefore, cassiterite U-Pb geochronology can constrain the timing of tin mineralization accurately and directly, making cassiterite the most ideal dating mineral for tin deposits (Gluson and Jones, 1992;Zhang et al, 2015;Neymark et al, 2018Neymark et al, , 2021. Isotope dilution-thermal ionization mass spectrometry (ID-TIMS) and laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) cassiterite U-Pb dating techniques have been developed to constrain tin mineralization events (Gluson and Jones, 1991, Yuan et al, 2008Neymark et al, 2018), and LA-ICP-MS techniques are now widely applied to obtain reliable ages of tin deposits (Zhang et al, 2015(Zhang et al, , 2017aGuo et al, 2019, Xiong et al, 2020.…”

Numerous skarn-type Sn deposits have been identified in the Nanling Range (South China), of which the Shizhuyuan W-Sn-Bi-Mo, Xianghualing Sn, Jinchuantang Sn-Bi, and Hehuaping Sn deposits are the largest. The Xianghualing deposit, which is the focus of this study, hosts a resource of 0.17 Mt Sn grading 0.93-1.39 wt% SnO 2 .Whether the distal skarn-type mineralization and the cassiterite-sulfide vein-type orebody in the Xianghualing district are genetically related to the Laiziling granitic pluton, which produced the proximal skarn-type Sn mineralization, however, is still unknown. The Xianghualing Sn mineralization occurs exclusively as cassiterite and has been subdivided into four ore-types: (1) lenticular proximal skarn ore (Cst I) containing the mineral assemblage cassiterite-pyrrhotite-chalcopyrite-actinolitewollastonite; (2) layered distal skarn ore (Cst II) containing the mineral assemblage cassiterite-pyrrhotite-chalcopyrite-actinolite; (3) vein cassiterite-sulfide ore (Cst III) distal from the skarn and associated granite containing the mineral assemblage cassiterite-arsenopyrite-pyrrhotite-muscovite-fluorite; and (4) veinlet Sn-Pb-Zn ore (Cst IV) distal from the skarn and associated granite containing the mineral assemblage cassiterite-galena-sphalerite-topaz-quartz. Here, we report the results of in situ laser ablation inductively coupled plasma mass spectrometric (LA-ICP-MS) U-Pb age determinations for garnet from the Xianghualing skarn and the above four types of cassiterite. Our age determinations indicate that there were two independent magmatic-hydrothermal events at ~160 and 156~150 Ma, both of which led to Sn mineralization. The first Sn mineralization event at ~160 Ma (Cst IV U-Pb ages of This is the peer-reviewed, final accepted version for American Mineralogist, published by the Mineralogical Society of America.The published version is subject to change.

“…Zircon U-Pb isotopic analysis was done using LA-ICP-MS at the USGS in Lakewood, CO. Standard laboratory procedures for zircon U-Pb dating were used and are outlined in Neymark et al (2021) and references therein. Beam size was about 30 microns, and the Plešovice (Sláma et al, 2008) age standard was used for data reduction.…”

he paper characterizes REE mineralization from carbonaceous metapelites of the Paleoproterozoic Mikhailovka Formation, which is the most ancient gold-bearing horizon of the Lena province (Bodaibo district, Irkutsk region). The conditions of metamorphism of the studied samples do not exceed those of chlorite-muscovite subfacies of greenschist facies (ilmenite-pyrrhotite isograde). The metamorphic allanite is a main REE host, which crystallized before the last stage of plastic deformation and folding. The matter source for its formation is related to REE and Th absorbed on organic matter and clay minerals, as well as the detrital monazite. Late hydrothermal-metasomatic processes resulted in its replacement by hydroxycarbonates (hydroxybastnaesite, ancylite) and hydrous phosphates of light REEs (rhabdophane?), while Th precipitated as a hydrous silicate. Findings of low-temperature metamorphic monazite and xenotime are also described.
