    Dec 01, 2009 We have evaluated olivine phenocrysts and host glass from a basalt lava flow and associated scoria cone in the Quartzville mining district located on the western forearc margin of the Oregon Cascades. Both lavas and scoria are contemporaneous determined through detailed field mapping, and they share similar petrological and geochemical characteristics. Ar-Ar dating indicates a

    In addition, olivine crystallized from pyroxenite-derived melts have a relatively low Mn/Zn ratio ( 14), while those from peridotite-derived melts exhibit a higher Mn/Zn ratio ( 14). The Mn/Zn values of the olivine in the Dali picrite range from 13.6 to 18.4, with most Mn/Zn values 15, also indicating a peridotite dominate source (Fig. 5 c)

    In other localities, olivine-bearing feldspathic pyroxenite grades into feldspathic harzburgite. The 4E grade (g/t) is typically 1-7 g/t with a Pt:Pd ratio of about 1:1.7. The Cu and Ni grades are on average 0.08% and 0.05%, respectively. ... The secondary cone crusher product will report to the secondary crusher product conveyor, which in turn

    Melts from a pyroxenite source and their crystallizing olivines should be enriched in NiO, because olivine is not controlling the partitioning of Ni. Sobolev et al.

    Mar 01, 2017 With the growing realization that pyroxenite, peridotite, and their respective derivative melts may interact to form a complex array of hybrid sources and magmas (e.g., Herzberg, 2011, Mallik and Dasgupta, 2012), olivine source determinations have evolved from a binary peridotite/pyroxenite predictive model to one where substantial ranges in

Dawson's (1967a) model is based largely on South African kimberlites and is different in many respects from the model postulated by Mikheyenko and Nenashev (1960), although both emphasize the role of

    Oct 10, 2020 Primitive subduction zone magmas provide information about the composition and thermal structure of the underlying mantle wedge. In the Colima Graben, Mexico, primitive lavas erupted from cinder cones range from high magnesium calc-alkaline basalts to high-K trachybasalts. This chemical diversity suggests that the sub-arc mantle wedge from which they derive is heterogeneous. To explore
