Texturally and mineralogically, the mudstone is dominantly composed of the finest, < 5 m[micro] calcite and silica grains, the latter documented in insoluble residue as rounded or irregular microparticles.
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.sub.2][O.sub.3] x 2Si[O.sub.2]), the proportions of which depend on the coal composition and processing [57, 58].
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 and chemically.
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.
Bryozoans may be the most mineralogically well-characterized invertebrate phylum.
Mineralogically these bodies are mainly composed of alkali feldspar, quartz, micas, and tourmalines and garnet at places.
The Jabal Farasan marble deposits were mineralogically and geochemically investigated and classified by Qadhi 2008.
As a group, asbestos has been classified as a carcinogen and is known to cause a pulmonary fibrotic disease called "asbestosis." Despite this generalization, all of these fiber types have distinct physicochemical properties (shape, durability in physiological fluids, surface chemistry, and aerodynamic properties), making the term "asbestos" mineralogically imprecise [7] (see Table 1).
Drilling focused on the Bastnaesite Zone, mineralogically the most favourable area of the greater Ngualla deposit and identified for initial production.
Mineralogically, the samples were nearly identical with 52 percent clay and 48 percent non-clay minerals, but the composition of metal ions released from the mineral surfaces varied considerably across the samples.
The results showed that each ware was mineralogically distinct and completely different from pottery made in the Solomon Islands, with characteristics unlikely to occur in the South Pacific.
A detailed petrographic investigation reveals that the studied samples from the Ambela complex represent three mineralogically different rock types, namely, alkali granite, alkali quartz syenite, and nepheline syenite (Figure 2).
