Ore deposits are loci on Earth where energy and mass flux greatly enhanced focussed, acting as magnifying lenses into metal transport, fractionation concentration mechanisms through the lithosphere. Here we show that metallogenic architecture of lithosphere is illuminated by geochemical signatures metasomatised mantle rocks post-subduction magmatic-hydrothermal mineral systems. Our data reveal anomalously gold tellurium rich magmatic sulfides in mantle-derived magmas emplaced lower crust...
Kimberlites represent magmas derived from great mantle depths and are the principal source of diamonds. their xenolith cargo have been extremely useful for determining chemical composition, melting regime evolution subcontinental mantle. The late-Devonian Udachnaya (means Fortuitous) pipe hosts largest diamond deposit in Russia (> 60% quantity value) one world, supplying gem-quality diamonds (~ 12% world production). Since its discovery 1956, kimberlite has become a "type locality"...
Quantifying the compositional evolution of mantle-derived melts from source to surface is fundamental for constraining nature primary and deep Earth composition. Despite abundant evidence interaction between carbonate-rich melts, including diamondiferous kimberlites, mantle wall rocks en route surface, effects this on melt compositions are poorly constrained. Here, we demonstrate a robust linear correlation Mg/Si ratios kimberlites their entrained components Mg/Fe olivine cores magmatic rims...
Mantle polymict breccias sampled by kimberlite magmas are complex mixtures of mantle minerals and rock clasts, cemented together olivine, phlogopite, orthopyroxene, ilmenite, rutile sulphides. Because the kimberlite-like texture (i.e. mineral clasts diverse origin composition set in a magmatic matrix) large geochemical heterogeneity preserved breccias, these rocks believed to derive from primitive or precursor magmas. Therefore, study such xenoliths can provide constraints on processes...
Kimberlites and orangeites (previously named Group-II kimberlites) are small-volume igneous rocks occurring in diatremes, sills dykes. They the main hosts for diamonds of scientific importance because they contain fragments entrained mantle crustal rocks, thus providing key information about subcontinental lithosphere. Orangeites ultrapotassic, H2O CO2-rich hosting minerals such as phlogopite, olivine, calcite apatite. The major, trace element isotopic compositions resemble those intensely...
Hypabyssal kimberlites are subvolcanic intrusive rocks crystallised from mantle-derived magmas poor in SiO2 and rich CO2 H2O. They complex, hybrid containing significant amounts of fragments, primarily olivine with rare diamonds, set a matrix essentially magmatic origin. Unambiguous identification requires careful petrographic examination combined mineral compositional analyses. Melt inclusion studies have shown that kimberlite melts contain higher alkali concentrations than previously...
Abstract Magmatic systems play a crucial role in enriching the crust with volatiles and elements that reside primarily within Earth’s mantle, including economically important metals like nickel, copper platinum-group elements. However, transport of these silicate magmas occurs dense sulfide liquids, which tend to coalesce, settle not be efficiently transported ascending magmas. Here we show textural observations, backed up carbon oxygen isotope data, indicate an intimate association between...
In-situ RbSr dating of mica by laser ablation ICP-MS/MS has recently emerged as a new tool to date range geological processes including magmatic, metamorphic and hydrothermal events. The majority age results presented are based on Rb/Sr calibration using the MicaMG pressed nano-powder pellet. However, some studies have reported low accuracy associated with ages this method, which attributed different properties natural mica. In work, we document systematic comparison between isotope-dilution...
A large 10-mer phage peptide library was panned against whole Escherichia coli cells, and an antimicrobial (QEKIRVRLSA) selected. The synthesized in monomeric dendrimeric tetrabranched form (multiple antigen [MAP]), which generally allows a dramatic increase of stability to peptidases proteases. antibacterial activity the E. much higher than that form. Modification original sequence, by residue substitution or sequence shortening, produced three different MAPs, M4 (QAKIRVRLSA), M5...

In response to the need for new antiviral agents, dendrimer-based molecules have been recognized as having a large number of potential therapeutic applications. They include peptide-derivatized dendrimers, which are hyperbranched synthetic well-defined consist peptidyl branching core and covalently attached surface functional peptides. However, few studies addressed their applications direct-acting agents. Here, we report on ability peptide dendrimer SB105 its derivative, SB105_A10, directly...
Kimberlites are rare, enigmatic, low-volume igneous rocks. They highly enriched in magnesium, volatiles (CO2 and H2O) incompatible trace elements thought to be the most deeply derived (>150 km) magmatic rocks on Earth. occur ancient thick continental lithosphere, forming intrusive sheets composite pipes, commonly clusters. Despite their rarity, kimberlites have attracted considerable attention because they entrain not only abundant mantle fragments but also diamonds, which can provide...
Significance Understanding how the Earth evolved from its accretion to present-day conditions is a major quest of sciences. This contribution focuses on evolution deepest realms our planet sampled by basalts in ocean islands (such as Hawaii) during last ∼100 150 million years and diamond-bearing kimberlites emplaced continents since ∼2 billion ago. Radiogenic isotope ratios are employed demonstrate that these lavas share common source, which includes component originated melt extraction soon...
