    On the melt differentiation in the intermediate chamber (by the example of differentiated intrusives of the western slope of the Southern Urals) by S. G. Kovalev, S. S. Kovalev

    Published 2024-04-01
    “…The calculated crystallization temperature of pyroxenes indicates that they crystallized together with olivine from the bulk of the rocks, and the established variations in the P–T parameters (T = 950–1045 ºC, P = 4.0–7.4 kbar) for plagioclase and amphibole complete the quantitative characteristics of high-temperature melt crystallization processes.It is shown that the calculated Р–Т parameters of the crystallization of the melt that formed the intrusive massif make it possible to classify its ultrabasic horizon as picrite complexes of the second type that we identified earlier.Modeling of the crystallization process carried out using two models – according to the algorithm of H.D. …”
