That means your rare earths are tied up mineralogically
with thorium and uranium," Kennedy said.
Altogether 385 samples from 10 geochemically and mineralogically
studied drill cores were used for the present description.
These rocks are mineralogically
composed of amphibole (actinolite and hornblende), quartz, garnet, clinozoisite, plagioclase, epidote, titanite and rutile.
brick differs mineralogically
from the San Pantaleo clays, suggesting
The sandstones are classified as texturally sub mature and mineralogically
mature quartz arenites and generally represent as first cycle of deposition.
The experiment was carried out in a screened greenhouse at the Center of Agricultural Sciences of the Federal University of Paraiba, using samples of six soils from the Paraiba state, classified according to EMBRAPA (2006) as Regolithic Neosol (RR), Grey Argisol (PAC), Haplic Luvisol (TX), RedYellow Argisol (PVA), Dystrophic Red Argisol (PVd) and Haplic Vertisol (VX), which were chemically, physically and mineralogically
characterized (Table 1).
Chemically and mineralogically
, fly ash is principally a vitreous aluminosilicate, containing various levels of alkalies, alkaline earths, transition metals, and some precipitated crystalline mullite (3[Al.
Powdered samples were mineralogically
characterized using a Philips PW-1710 X-ray diffraction (XRD) system operating at 40 kV and 30 mA, and employing monochromated CuK[alpha] radiation.
These three rocks come from different geological provinces and are thus expected to be different mineralogically
These respective deposits have been geologically, physico-chemically and mineralogically
characterised in other studies (Diko and Ekosse, 2012; Diko, 2012; Diko and Ekosse, 2014).
The Burnthill Granite is a texturally and mineralogically
heterogeneous intrusion of coarse- to very coarse-grained biotite granite comprising a dominant phase of pink to red, medium- to coarse-grained, equigranular to seriate, alkali feldspar-phyric granite (Fig.
Lower samples of the BII Bentonite are mineralogically
quite similar, having a minor amount of calcite and pyrite in sample 1.
