“…A phlogopite-calcite-apatite paragenetic assemblage has yielded a Rb-Sr isochron age of 460 ± 7 Ma Reznitskii et al, 1999). This is further constrained by U-Pb zircon ages of 471 ± 1 Ma (Salnikova et al 1998) and 447 ± 2 Ma (Reznitskii et al, 2000) from early syenites and monzonites and later 'post-phlogopitic' pegmatites respectively.…”

U–Pb and Th–Pb dating of apatite by LA-ICPMS

Apatite is a common U-and Th-bearing accessory mineral in igneous and metamorphic rocks, and a minor but widespread detrital component in clastic sedimentary rocks. U-Pb and Th-Pb dating of apatite has potential application in sedimentary provenance studies, as it likely represents first cycle detritus compared to the polycyclic behaviour of zircon. However, low U, Th and radiogenic Pb concentrations, elevated common Pb and the lack of a U-Th-Pb apatite standard remain significant challenges in dating apatite by LA-ICPMS, and consequently in developing the chronometer as a provenance tool.This study has determined U-Pb and Th-Pb ages for seven well known apatite occurrences (Durango, Emerald Lake, Kovdor, Mineville, Mudtank, Otter Lake and Slyudyanka) by LA-ICPMS. Analytical procedures involved rastering a 10μm spot over a 40×40μm square to a depth of 10μm using a Geolas 193nm ArF excimer laser coupled to a Thermo ElementXR single-collector ICPMS. These raster conditions minimized laser-induced inter-element fractionation which was corrected for using the back-calculated intercept of the time-resolved signal. A Tl-U-Bi-Np tracer solution was aspirated with the sample into the plasma to correct for instrument mass bias.External standards (Plešovice and 91500 zircon, NIST SRM 610 and 612 silicate glasses and STDP5 phosphate glass) along with Kovdor apatite were analysed to monitor U-Pb, Th-Pb and Pb-Pb ratios. Age calculations employed between 11 and 33 analyses per sample and used a weighted average of the common Pb-corrected ages, a Tera-Wasserburg Concordia intercept age and a Tera-Wasserburg Concordia intercept age anchored through

“…Vernikovsky et al (2003) have also identified three main Neoproterozoic tectonic events along the western margin of the Siberia Craton in forming the Yenisey Ridge fold-and-thrust belt: at 880-860 Ma, 760-720 Ma and 700-630 Ma. Khain et al (2002) and Kuzmichev et al (2005) proposed that Mesoproterozoic to Neo- Kelty et al (2008) and Salnikova et al (1998Salnikova et al ( , 2001 proterozoic crust (1.1-0.8 Ga) was produced by subduction-related magmatism. These data establish that many of the blocks in the CAOB record Neoproterozoic tectonic events.…”

a b s t r a c tThe Linxi Formation occupies an extensive area in the eastern Inner Mongolia in the Central Asian Orogenic Belt (CAOB). The Linxi Formation is composed of slate, siltstone, sandstone and plant, lamellibranch microfossils in the associated strata. Major and trace element data (including REE) for sandstones from the formation indicate that these rocks have a greywacke protolith and have been deposited during a strong tectonic activity. LA-ICPMS UePb dating of detrital zircons yield ages of 1801 to 238 Ma for four samples from the Linxi Formation. 425e585 Ma, together with the w500 Ma age for the metamorphism event previously determined for Northeast China, indicates that their provenance is the metamorphic rocks of Pan-African age that have a tectonic affinity to NE China. A few older zircons with UePb ages at 1689e1801 Ma, 1307e1414 Ma, 593e978 Ma are also present, revealing the Neoproterozoic history of NE China. The youngest population shows a peak at ca. 252 Ma, suggesting that the main deposition of the Linxi Formation was at late Permain. Moreover, the ca. 250 Ma zircon grains of all four samples yield weighted mean 206 Pb/ 238 U ages of 250 AE 3 Ma, 248 AE 3 Ma, 249 AE 3 Ma, and 250 AE 2 Ma, respectively. These ages, together with the youngest zircon age in the sample ZJB-28 (ca. 238 Ma), suggest that the deposition of the Linxi Formation extended to the early Triassic. Combining with previous results, we suggest that the final collision of the Central Asian Orogenic Belt (CAOB) in the southern of Linxi Formation, which located in the SolonkereXra MoroneChangchun suture, and the timing for final collision should be at early Triassic.Ó 2015, China University of Geosciences (Beijing) and Peking University.
