“…Heaman [1989] and Smith et al [1989] originally suggested that perovskite should record the primary geochemical and isotopic signature with respect to the timing of emplacement and origin of the kimberlitic magma, prior to any contamination and weathering, based on TIMS U-Pb and Sr-Nd isotopic studies on perovskite. More recent isotopic studies on perovskite by Paton et al [2007], Wu et al [2010Wu et al [ , 2013, Zurevinski et al [2011], Sarkar et al [2014Sarkar et al [ , 2015, and Sun et al [2014] have further established these concepts. However, the Sr isotopic study of Malarkey et al [2010] demonstrates perovskite recording crustal contamination, suggesting some caution needs to be exercised.…”

“…U-Pb dating of groundmass perovskite was initially investigated using the ID-TIMS method on perovskite-rich concentrate [(Kramers and Smith, 1983;Smith et al, 1989], pure perovskite fractions [Heaman, 1989], and more recently by spatially resolved in situ methods (ion microprobe: Kinny et al [1997]; Wu et al [2010]; Sun et al [2014]) or LA-ICPMS techniques [Cox and Wilton, 2006;Wu et al, 2010Wu et al, , 2013. Perovskite (CaTiO 3 ) is a groundmass mineral that is observed in ultramafic and mafic, silica-undersaturated, subalkaline, and alkaline rocks e.g., kimberlite, carbonatite, nephelinite, melilitite, and ultramafic lamprophyre (UML).…”

Thirty new high‐precision U‐Pb perovskite and zircon ages from kimberlites in central North America delineate a corridor of mid‐Cretaceous (115–92 Ma) magmatism that extends ∼4000 km from Somerset Island in Arctic Canada through central Saskatchewan to Kansas, USA. The least contaminated whole rock Sr, Nd, and Hf isotopic data, coupled with Sr isotopic data from groundmass perovskite indicates an exceptionally limited range in Sr‐Nd‐Hf isotopic compositions, clustering at the low ɛNd end of the OIB array. These isotopic compositions are distinct from other studied North American kimberlites and point to a sublithospheric source region. This mid‐Cretaceous kimberlite magmatism cannot be related to mantle plumes associated with the African or Pacific large low‐shear wave velocity province (LLSVP). All three kimberlite fields are adjacent to strongly attenuated lithosphere at the edge of the North American craton. This facilitated edge‐driven convection, a top‐down driven processes that caused decompression melting of the transition zone or overlying asthenosphere. The inversion of ringwoodite and/or wadsleyite and release of H2O, with subsequent metasomatism and synchronous wet partial melting generates a hot CO2 and H2O‐rich protokimberlite melt. Emplacement in the crust is controlled by local lithospheric factors; all three kimberlite fields have mid‐Cretaceous age, reactivated major deep‐seated structures that facilitated kimberlite melt transit through the lithosphere.

We have studied variations in the structure and composition of minerals from the pipes of the Yakutian kimberlite province (YKP) in different mantle terranes of the Siberian craton. The study was based on an extensive database, including the microprobe analysis datasets consolidated by IGM, IG, IEC and IGDNM SB RAS and ALROSA and geochemical analysis of minerals performed by LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry). The reconstruction shows layering under the tubes, including 6-7 slab that were probably formed due to subduction; the slabs are separated by pyroxenitic, eclogitic and metasomatic layers and dunite lenses. Transects and mantle profiles across kimberlite fields are constructed. Within the limits of the revealed tectonic terranes, we assume a collage of microplates formed in the early-middle Archean. Extended submeridional structures of the tectonic terranes are not always confirmed at the mantle level. Beneath the Anabar and Aldan shields, the mantle sections show more coarse layers and 3-4 large horizons of dunites with garnet and pyroxene nests separated by ilmenite-phlogopite metasomatites and pyroxenites. Terranes representing the suture zones between the protocratons (e.g. Khapchan) are often saturated with eclogites and pyroxenites that may occur as leghthy ascending bodies of magmatic eclogites penetrating through the mantle lithosphere structure (ML). A nearly ubiquitous pyroxenite layer at the level of 3.5-4.5 GPa formed probably in the early Archean with a high heat flux during melting of eclogites and was subsequently traced by plume melts. Within the early Archean protocratons-granite-greenstone terranes (Tungus, Markha, Berekta, and Sharyzhalgai, ~3.8-3.0 Gyr [Gladkochub et al., 2019], the mantle lithosphere is less depleted and largely metasomatized. The ML structure of the Daldyn and Magan granulite-orthogneiss terranes is layered with folding revealed in the north-to-south sections from the Udachnaya pipe to the Krasnopresnenskaya pipe, which is less pronounced in the latitudinal direction. From the Daldyn field to the Alakit field, there is an increase in the degree of metasomatism, and higher alkalinity of pyroxenes and larger amounts of phlogopite are noted. The most productive Aikhal and Yubileinaya pipes are confined to a dunite core, which is accompanied by a change in the specialization of high-charge elements Ta-Nb to Zr-Hf. Within the limits of the Magan terrane, the thin-layer structure of the middle GEODYNAMICS & TECTONOPHYSICS
