All these indicate the Ga'erqiong rock is not generated from crystallization differentiation of mantle-derived basaltic magma
Objective: The worlds greatest resources of platinum-group elements, Cr and V are found in almost monomineralic, metre-scale, layers of Cr- and Fe-Ti oxides that formed during solidification of large bodies of basaltic magma
trapped in the Earths crust (i.
Minerals crystallize from basaltic magma
in a certain order, explained Alian Wang, PhD, research professor in earth and planetary sciences in Arts & Sciences at Washington University.
The motions of Earth's plates mix crustal rocks and water with basaltic magma
inside the planet, producing a variety of volcanic rocks that are enriched in silica.
The former, having annelaed under high temperature, are commonly refered to as the mantle (tectonized) peridotites, while the latter are considered to have crystallized as comulates from a basaltic magma
in the ophiolite magma chamber.
The LRO scientists think pockets of the newfound silica-based rock must have been created as basaltic magma
deep in the moon melted some of the silica-containing deep crust.
40-60]) and lack of complementary mafic-ultramafic cumulates, it is inferred that magmas parental to massif-type anorthosite originated from the fractional crystallization and contamination of basaltic magma
in the crust-mantle boundary zone (Duchesne 1984; Ashwal 1993; Emslie et al.
A standard phase diagram of a basaltic magma
(X) undergoing olivine-enstatite fractionation shows that the magma composition in each chamber will be driven down the olivine-enstatitc reaction curve (Fig.
However, the Alphonsus event seems to have involved the intrusion of basaltic magma
into the [?
Steam explosions due to heating of water-saturated sand and silt strata from rising basaltic magma
formed Kilbourne Hole.
Kilauea has basaltic magma
, which allows lots of gases to easily escape before erupting, making the lava runny.
The mantle rock begins to melt and form basaltic magma
, which then percolates up toward the surface through cracks and pores in the remaining solid, yet deforming, rock.
