title: A review of the main tectonic settings of Neoarchaean ore deposits and mineral occurrences in the northern São Francisco Craton, NE Brazil

description: In this paper, a compilation of the main Neoarchaean ore deposits, and their tectonic settings, in the northern São Francisco Craton, NE Brazil is presented. The Serrinha and Gavião blocks split up in the Neoarchaean, giving rise to juvenile rocks and metavolcanic-sedimentary sequences within the so-called Mundo Novo-Caraíba-Ibicuí sea. The rocks from the southern Gavião Block served as basement for the Contendas-Mirante sequence, where the Jacaré River Vanadium mine is situated in a stratified gabbro-anorthosite mafic sill, which intruded a Neoarchaean shear zone. On the northern part of the Gavião Block, where oceanic crust was identified by the presence of the Mundo Novo greenstone belt, hydrothermal mineralizations of both lead and zinc were mapped in calc-silicate rocks, which are associated to metamorphosed tholeiitic seafloor basalts and these metabasalts are tectonically intercalated with metadacites. In the Jequié Block, occurs the Ibicuí-Iguaí Iron District, which lies in the suture zone between this tectonic unit and the Itabuna-Salvador-Curaçá belt. These are rocks comprising a sequence of metabasalts and metavolcanic tuff, metakomatiites, kinzigites, quartzites and itabirites. In this belt also occurs the southern Bahia manganese district, where the mineralization is hosted in granulitized metavolcanic-sedimentary sequences. The ore protoliths are chemical sediments composed of spessartite, pyroxmangite, rhodonite, rhodochrosite, magnetite, mesoperthite and quartz. The reducing characteristics of the primary environment are confirmed by the presence of graphite and manganese sulphide (alabandite). This mineralogy produced through supergenic processes, ores with great reserves of pyrolusite and psilomelane. In the northern part of the Itabuna-Salvador-Curaçá Belt, an island arc was identified, where mafic-ultramafic bodies (2580 Ma) intruded at its base, giving rise to the Curaçá-Caraíba Valley Cupriferous District. These bornite and chalcopyrite-rich bodies were generated from a calc-alkaline magma that originated multiple Cu-rich gabbroic and pyroxenitic intrusions.

title: Back-arc magmatism of the Proto-Tethys Ocean in the West Kunlun Orogenic Belt: evidence from the Ordovician Nanpingxueshan Nb-enriched gabbros

description: The West Kunlun Orogenic Belt (WKOB) in the northwestern Tibetan Plateau records key information about the tectonic evolution of the Proto-Tethys Ocean. To further constrain the Early Palaeozoic tectonic evolution of the WKOB, we report petrography, geochronology, whole-rock geochemistry, and Sr-Nd-Hf-O isotope data of the newly identified Ordovician Nanpingxueshan gabbros in the southern WKOB. Laser ablation-inductively coupled plasma-mass spectroscopy (LA-MC-ICP-MS) U-Pb zircon dating reveals that the gabbroic intrusion was emplaced during 476–471 Ma. Geochemically, the gabbroic rocks exhibit a tholeiitic signature and can be subdivided into two groups, i.e. normal arc-like gabbros (AGs) and Nb-enriched gabbros (NEGs). The AGs have TiO<sub>2</sub> (1.20–1.64%), P<sub>2</sub>O<sub>5</sub> (0.18–0.25%), and Nb (4.60–7.64 ppm) contents, fractionated REE patterns ((La/Yb)<sub>N</sub> = 2.64–4.11), and Nb-Ta depletion (Nb/La = 0.37–0.50). Compared with AGs, the NEGs have higher TiO<sub>2</sub> (1.74–2.68%), P<sub>2</sub>O<sub>5</sub> (0.34–0.55%), and Nb (10.79–14.08 ppm) contents and Nb/La ratios of 0.45–0.53, which are similar to typical Nb-enriched arc basalts. Isotopically, the AGs have depleted whole-rock ε<sub>Nd</sub>(t) values of 3.22 to 4.04 and negative to positive zircon ε<sub>Hf</sub>(t) values of −1.8 to 7.8, while the NEGs exhibit slightly lower whole-rock ε<sub>Nd</sub>(t) values of 0.69 to 3.18, zircon ε<sub>Hf</sub>(t) values of −7.8 to 4.6, and mostly δ<sup>18</sup>O values greater than those of normal mantle zircon. Integrated analyses reveal that the AGs and NEGs can be attributed to a similar mantle source metasomatized by different proportions of subducted sediment-derived melt during the subduction process. Our new data, combined with the results of previous studies, suggest that the southward subduction of the Proto-Tethys Ocean under the WKOB initiated at ca. 530 Ma. The long-term southward subduction led to the formation of the massive Early Palaeozoic accretionary complex in the South Kunlun Terrane, while trench retreat led to migration of the arc magmatism northward from the Mazar – Tianshuihai Terrane to the South Kunlun Terrane, as well as back-arc extension in the Mazar – Tianshuihai Terrane.

title: Petrogenesis, geochronology, and tectonic setting of the Calymmian 1.45–1.50 Ga basic magmatism in the Southern Ribeira Belt, Brazil: evidence of intracontinental rifting and Columbia break-up

description: We present new petrographic, whole-rock geochemistry, and SHRIMP U – Pb zircon geochronological data of metabasic rocks interlayered as sills in the metasedimentary units of the Perau and Betara formations, Votuverava Group, Southern Ribeira Belt, Brazil. These formations overlie ~ 1.8 Ga Paleoproterozoic metagranitoids that represent basement inliers from the Paranapanema Craton. Petrography and whole-rock geochemistry allow the recognition of four groups, ranging from primitive to evolved compositions: i) cumulatic metadolerites (G1), ii) isotropic metadolerites (G2), iii) ortho-amphibolites (G3); and iv) ferroan ortho-amphibolites (G4). They exhibit tholeiitic subalkali basaltic composition, near-flat REE patterns, and signatures between N- and E-MORB. Fractional crystallization under low fO2 conditions is the main petrogenetic process controlling the magmatic evolution, as observed by Ti/V and Cr/Y ratio and tholeiitic trends. Crustal contamination signatures are observed through negative Nb anomaly, Th/Nb-Ti/V proxies trends, LILE enrichment, and, also, assimilated xenocryst zircons aged ~ 2.2 Ga. REE and trace element systematics indicate that the basic magmas were generated by ~ 20–10% partial melting of a model asthenospheric mantle source within spinel facies. TiO2/Yb-Nb/Yb and Nb/Yb-Zr/Yb ratio proxies and P-MORB metabasic rocks, previously described in the literature within the Votuverava Group, suggest a plume-influenced melt. A new SHRIMP U – Pb zircon age of 1448 ± 11 Ma was determined for an ortho-amphibolite sample (G3 group). We propose an intracontinental tectonic setting for the genesis of the metadolerites whitin the Perau and Betara formations, suggesting that this extensional event is associated with the Paranapanema Craton rifting. Furthermore, the genesis of the studied metabasic rocks could be associated with a regional extensional event during Calymmian times (~1.5–1.45 Ga), which generated basic magmatism in several other cratons, such as the Congo, São Francisco, Siberian, Laurentian, and China cratons, linked to the break-up of the Columbia Supercontinent.

title: Early Cretaceous mafic dikes in the eastern North China Craton: implications for the effect of slab subduction on the mantle sources

description: The Early Cretaceous mafic dikes occur widely in the major gold districts of the eastern North China Craton (NCC), which are coeval and cospatial with many gold deposits, and these mantle-derived magmatic rocks provide a window to investigate the mantle compositions and metasomatism. Here, we present the Sr-Nd-Pb isotopic compositions of the Xiaoqinling mafic dikes and compare with regional geochemical and isotopic data for mafic dikes in Jiaodong, Xiaoqinling and interior of the NCC. The results indicate that the Early Cretaceous mafic dikes of Xiaoqinling and Jiaodong low-Ti group were derived from arc-like subcontinental lithospheric mantle (SCLM), that of Jiaodong high-Ti group were derived from OIB-like asthenospheric mantle, and that of the interior NCC were derived from both of lithospheric and asthenospheric mantle. Further, their mantle sources during Early Cretaceous were dominantly metasomatized by aqueous fluids derived from subduction slab as well as by limited melt and carbonate. Furthermore, the mantle beneath the Jiaodong low-Ti and Xiaoqinling is mainly characterized by EM2 type, whereas that of the interior NCC is mainly of EM1 type. Besides, the whole-rock Nd and zircon Hf isotopic compositions of these mafic dikes show clearly temporal and spatial variations with their ages of 145 ~ 110 Ma, reflecting that the mantle of the eastern NCC changed from the ancient IAB-like SCLM to juvenile OIB-like mantle through metasomatism. This process was controlled by the slab rollback of the paleo-Pacific plate during the extension.
