Solid-state fabrics in granites are generally used to track distributed regional-scale strain and to document kinematics of localized shear zones. In some cases, solid-state fabrics are used to infer synemplacement deformation, such as the deformation of a marginal facies of an intrusion by an internal facies (e.g., de Saint Blanquat et al., 2001 ).
That''s what gives granite its many hues. The different colours of granite are due to its mineral and rock make-up. In order to be considered granite, the rock must contain at least 20 per cent quartz. Nature created these beautiful colours, we only enhance it by …
Most of the tungsten ore deposits are also spatially related to Yenshanian granites. These granites include several intrusions, isotopically dated at 160–180 m. y. and 70–100 m. y. The concentration of trace elements, especially W Mo, Sn, Ta, Nb, Li, and F

Due to their alkaline composition, they are still referred to as "A-type" granites (Bickford et al., 2015). Mesoproterozoic plutonism initiated in eastern Laurentia around 1.5 Ga, and most ages in this area are 1.5–1.45 Ga with an additional peak in age distribution at ca. 1.37 Ga ( Bickford et al., 2015 ).

Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy.
All black granites from our catalogue have a variety of applications and processing, easily meeting our customer''s requirements for flooring, stair covering, table tops, kitchen tops or vanity tops. Our imagination is the only limit. As we''ve already mentioned, you

· The loss of mineral portions in the weathered granites, particularly linked to biotite and along the fissures, increases the roughness but does not significantly affect gloss. A relationship can be drawn between gloss and the L * -parameter (Fig. 9 ), which similarly was found by Sanmartín et al. ( 2011 ) in polished granites.
