The second one corresponds to greenschist facies (Figure 30, represented by chlorite + muscovite + epidotesr-plagioclase (albite
) + quartz + actinolite.

The aim of this study is the determination of majority minerals (chlorite, muscovite, albite
and quartz) in claystones and clay shales by IR spectroscopy combined with partial least-squares regression.
In addition to the TOPAZ series, Gem Hsin is also planning a September 2011 launch of a new series, called ALBITE
, to provide consumers with another innovative home-lighting product.
Associated with the loose crystals and crystal groups of axinite are lustrous, snow-white albite
crystals to 1 cm.
The dominant phases in all drillcore samples P1-P6 are calcite and dolomite; quartz, feldspars (K-feldspar and in trace amounts of albite
), clay minerals (illite/illite-smectite); and ettringite (Fig.
The minerals of the matrix are less than 30 microns in size and consist of a rather isotropic intergrowth of K-feldspar, albite
, quartz, white mica, chlorite, epidote, allanite, calcite, with accessory stilpnomelane, biotite, pyrrhotite/pyrite, sphalerite, apatite, zircon, and ilmenite decomposed to titanite and rutile.
Formation of secondary albite
after K-feldspar is manifest as either fine-grained sacchroidal albite
or euhedral platy cleavelandite.
Hydrothermal alteration is distinct including secondary quartz, biotite, K-feldspar, albite
and fuchsite alteration are locally observed.

(ii) transferring stable silicon-rich components, such as kaolinite and quartz, to easily soluble compounds, for example, albite
and nephelite: in order to improve the Si[O.sub.2] extraction efficiency , as-treated coal gangue materials were mixed with [Na.sub.2]C[O.sub.3] in the respect mass ratio of 0.8, 0.9,1.0,1.2,1.3,1.4,1.5, and 1.6 and calcinated at 750[degrees]C, 800[degrees]C, 850[degrees]C, and 900[degrees]C for 1,2, 3, 4, and 5 hours,
