The composition of clinopyroxenes is indicative for chemical and physical properties of mantle substrates. In this study, we present the results of Raman spectroscopy examination of clinopyroxene inclusions in natural diamonds (n = 51) and clinopyroxenes from mantle xenoliths of peridotites and eclogites from kimberlites (n = 28). The chemical composition of studied clinopyroxenes shows wide variations indicating their origin in different mantle lithologies. All clinopyroxenes have intense Raman modes corresponding to metal-oxygen translation (~300–500 cm−1), stretching vibrations of bridging O-Si-Obr (ν11~670 cm−1), and nonbridging atoms O-Si-Onbr (ν16~1000 cm−1). The peak position of the stretching vibration mode (ν11) for the studied clinopyroxenes varies in a wide range (23 cm−1) and generally correlates with their chemical composition and reflects the diopside-jadeite heterovalent isomorphism. These correlations may be used for rough estimation of these compounds using the non-destructive Raman spectroscopy technique.

Composition of the Sub‐Cratonic Mantle of the Guiana Shield Inferred From Diamond‐Hosted Inclusions

The composition of diamond‐hosted inclusions provides insight into the character of the sub‐cratonic lithosphere of the Guiana Shield. Guyana's Paleoproterozoic diamonds preserve an inclusion suite comprised of forsterite (Fo ∼89.3–91.8), enstatite, chromite, and Cr‐pyrope. Raman thermobarometry of entrapped olivine and pyrope inclusions indicate entrapment pressures of ∼5.3–7.0 GPa. Unpolarized Fourier transform infrared spectroscopic measurements of forsterite and enstatite inclusions produce low absorbances from OH. Using established calibrations, those absorbances indicate forsterite and enstatite contain median values of 26 ± 14 and 14 ± 18 ppm H2O, respectively, and suggest a high effective viscosity of 1023.7 ± 2.1 Pa∙s for the lithospheric mantle. When combined with inclusion thermobarometry, diamond residence temperatures suggest paleo‐geotherms ranging from 35 to 40 mW m−2. Low‐to‐moderate Fe2O3 content (1.9 ± 0.8 wt.%) and low oxygen fugacity (log ƒO2 (ΔFMQ) −1.6 ± 1.1) determined from chromite inclusions indicate crystallization in reducing conditions. Forsterite and chromite inclusions retain evidence for metasomatic alteration, including Mn‐enrichment in forsterite and chromite rich in Zn. These characteristics indicate that the sub‐cratonic lithosphere of the Guiana Shield experienced episodes of partial melting and fluid‐driven metasomatism of dry, strongly viscous, and moderately depleted garnet‐spinel harzburgite. The Guiana Shield has been relatively stable since the Paleoproterozoic, meaning diamond inclusions may also provide the best means for understanding current conditions in the region's lithospheric mantle.

“…The longer are the periods of tectonic erosion and subduction, the larger will be the volume of the material arriving to the mantle, metasomatising it and thus reducing melting temperatures. According to rough evaluations based on the average rate of ocean plate subduction and the ages of mantle metasomatism beneath the Siberian platform and the age of kimberlite magmatism therein (Kolesnichenko et al, 2017), the age of metasomatism in the upper mantle can be 50-100 Ma younger than that of the maximal subduction and erosion. For example, the Siberia, Kazakhstan, Tarim and North China continents, which later amalgamated to form supercontinent Laurasia at ca.…”

Pacific-type orogenic belts: linking evolution of oceans, active margins and intra-plate magmatism

Pacific-type orogens (fold belts) hosting accretionary complexes are places keeping records of the evolution of paleo-oceans, and formation and transformation of continental crust at their active convergent margins. Pacific-type orogeny induces destruction of crustal materials, their subduction to the deep mantle, generation of hydrouscarbonated plumes in the mantle transition zone (MTZ) and its related intra-plate magmatism. We propose a new approach for linking paleo-oceans, active margins and intra-plate magmatism in central and eastern Asia. The approach "stands" on three "whales": the model of Ocean Plate Stratigraphy (OPS), the parameters of Pacific-type convergent margins and a model of hydrous-carbonated plumes. The OPS model evolved from extensive studies of accretionary complexes in the western Pacific, in particular, in Japan; it allows differentiating oceanic plates of one paleoocean and evaluating their sizes and ages. An important issue for reconstructing the history of paleo-oceans is to estimate major parameters of the Pacific-type convergent margins: accreting vs. eroding, geometrical length, and life time. For the eroding margins we must define major periods of tectonic erosion and transportation of oceanic and continental materials to the deep mantle and evaluate a possibility of their accumulation in the MTZ. All this would allow us to develop a holistic model linking the evolution of paleooceans, the accretion and erosion of oceanic and continental crust materials at Pacific-type convergent margins, mantle metasomatism and intra-plate magmatism.
