Abstract The study of kimberlite rocks is important as they provide critical information regarding the composition and dynamics continental mantle are principal source diamonds. Despite many decades research, original compositions melts, which thought to be derived from depths > 150 km, remain highly debatable due processes that can significantly modify their during ascent emplacement. Snapshots kimberlite‐related melts were entrapped secondary melt inclusions hosted in olivine sheared...
Abstract Elucidating the origin, composition and physical properties of primary kimberlite melts is crucial to our understanding their source, petrogenesis, ascent mechanisms ultimately origin diamonds. Recently, there has been a growing interest in study olivine, which one most abundant minerals kimberlites with xenocrystic, metamorphic (mantle) magmatic origins. Olivine earliest crystallise magmas, presence ubiquitous zoning (e.g. cores, internal zones, transitional rims, rinds, outmost...
The petrologically unique Udachnaya-East kimberlite (Siberia, Russia) is characterised by unserpentinised and H2O-poor volcaniclastic coherent units that contain fresh olivine, along with abundant alkali-rich carbonates, chlorides, sulphides sulphates in the groundmass. These mineralogical geochemical characteristics have led to two divergent models advocate different origins. It has been suggested from are representative of pristine unaltered kimberlite. Conversely, alkali-chlorine-sulphur...
Kaapvaal lamproites (aka orangeites) are a group of volatile-rich (H2O, CO2), micaceous, ultrapotassic igneous rocks that unique to the craton in southern Africa. However, composition melts give rise these remains poorly understood due overprinting effects contamination by mantle and crustal material, volatile exsolution, fractional crystallisation post-magmatic alteration. Consequently, this lack reliable data on initial lamproite hampers our understanding their source, petrogenesis ascent...
Abstract The Norilsk 1 intrusion (Russia), renowned for its abundance of sulfide ores, contains an upper contact zone, which hosts sulfide-poor and Cr spinel platinum group element (PGE)-rich discontinuous reefs with significant economic potential. Located within strongly inhomogeneous rocks various compositions, the origin these is complex debated. Enrichment in PGEs distributed heterogeneously, occasionally occurring extremely dense disseminations spinel, are unusual other intrusion....
The emplacement age of the Great Udzha Dyke (northern Siberian Craton) was determined by U-Pb dating apatite using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). This produced an 1386 ± 30 Ma. dyke along with two other adjacent intrusions, which cross-cut sedimentary units paleo-rift, were subjected to paleomagnetic investigation. poles for paleo-rift intrusions are consistent previous results published Chieress in Anabar shield Craton (1384 2 Ma). Our suggest that...
Abstract The Norilsk-Talnakh ore district in the northwestern Siberian platform contains globally unique reserves of Cu-Ni-sulfides with Pt and, especially, Pd. Oktyabrsk deposit, which is one largest district, spatially and genetically associated Kharaelakh mafic-ultramafic intrusion its exceptionally large metamorphic metasomatic aureoles. In this study, we employed situ laser ablation-inductively coupled plasma-mass spectrometry U-Pb isotope dating apatite, titanite, garnet, perovskite...
