Data from: Petrogenetic studies of Permian pegmatites in the Chinese Altay: implications for a two-stage post-collisional magmatism model
<p>Understanding the petrogenesis of rare-metal pegmatites is important for understanding ore-forming processes and their tectonic settings. In this study, we performed zircon U-Pb geochronological and Hf-O isotopic analyses of the Xiaokalasu (XKLS), Dakalasu (DKLS) and Yelaman (YLM) pegmatites in the Chinese Altay orogen. These pegmatites have low εHf(t) values (-0.6 ~ +4.3), two-stage model ages of 989 ~ 1293 Ma, and high δ<sup>18</sup>O values (+6.52 ~ +11.31), indicating that they may have been derived from the anatexis of mature sedimentary rocks in the deep crust, with a small amount of mantle-derived or juvenile material. Geochronological and Hf-O isotopic data for granitic intrusions in the Chinese Altay Mountains indicate that the εHf(t) values decreased from the Permian to the Triassic, which implies that two-stage post-collisional magmatism occurred in this region. During the Permian, the thin lower crust was cold; thus, magmatism likely originated in the deep crust close to the Moho surface and involved intense mantle-crust interactions. During the Triassic, asthenospheric upwelling provided heat to the lower crust, which increased the geothermal gradient and led to the anatexis of shallow crustal material.</p>

Oligocene–Miocene exhumation of the Pinaleño metamorphic core complex, southeastern Arizona: support for magmatism and plate margin reorganization as controls on regional exhumation trends
<p>We present thermochronology data from igneous and metamorphic rock samples collected from the Pinale<strong>ñ</strong>o Mountains, southeast Arizona, U.S.A. Our interpretations of the data are described and discussed in a paper in the journal Tectonics, titled “Oligocene–Miocene exhumation of the Pinaleño metamorphic core complex, southeastern Arizona: support for magmatism and plate margin reorganization as controls on regional exhumation trends.” New data include biotite and white mica Ar/Ar analyses, apatite fission track analyses, apatite (U-Th-Sm)/He analyses, and zircon (U-Th-Sm)/He analyses. The data were used for inverse HeFTy modeling and forward radiation damage and annealing modeling (RDAAM) to investigate time-temperature histories. The data set comprises a table summarizing the results of Ar/Ar analyses (Table S1), a table with the detailed results of zircon (U-Th-Sm)/He thermochronology (Table S2), a table with the detailed results of apatite (U-Th-Sm)/He thermochronology (Table S3), a table summarizing the results of apatite fission track analyses, including radial plots (Table S4), and a table summarizing the input data and constraints used for inverse modeling.</p>

Geophysical and geochemical evidence for a new mafic magmatic province within the Northwest Shelf of Australia: Supplementary material
<p>Buried magmatic provinces are rarely identified and difficult to classify. The Northwest Shelf of Australia contains large volumes of potentially interconnected mafic igneous material across several sedimentary basins. However, limited study and a lack of surface exposure have prevented detailed description and classification of these rocks. In this study, the distribution and composition of these mafic igneous rocks is described using an integrated geophysical and geochemical approach, which included over 10,000 km of 2D historical seismic data, well log data and chemical analysis of samples from 14 wells across the Browse, Roebuck, Canning and North Carnarvon basins. Using this combined dataset, we demonstrate interconnectivity of buried mafic igneous rocks across the Northwest Shelf and calculate for these mafic rocks a total surface area exceeding 280,000 km<sup>2</sup> and a cumulative minimum volume of ~140,000 km<sup>3</sup>. Petrology and geochemistry of samples indicate they are basaltic and doleritic with alkaline and sub-alkaline compositions and formed in a continental rift setting. Collectively, the igneous rocks meet the criteria for classification as a mafic magmatic province (MMP) and closely match the criteria required for classification as a large igneous province (LIP). The interconnected mafic igneous rocks found across the Northwest Shelf of Australia are here formally defined as an MMP. Emplacement of the Northwest Shelf MMP may represent hotspot magmatism that could have initiated rifting of the Cimmerian Block from NW Australia near the end Permian, and may have broad implications for petroleum prospectivity, CO<sub>2</sub> sequestration and new resource opportunities in the Northwest Shelf.</p>
