2002-6-1  More deformed outcrops of higher metamorphic grade (mostly greenschist facies) contain 10–30 vol% quartz veins. These outcrops underwent mass addition of externally derived silica into quartz veins, accompanied by addition of Na and removal of K and W. Average silica additions suggest a time-integrated fluid flux of ∼10 4 –10 5

2000-8-1  Our results indicate that up to 100% of the quartz silt in our samples does not originate from the continental crust. Instead, it appears to have precipitated early in diagenesis in algal cysts and other pore spaces, with silica derived from the dissolution of opaline skeletons of planktonic organisms, such as radiolaria and diatoms.

Fused Silica vs Fused Quartz in Precision Optics

Fused Silica vs Fused Quartz Fused Silica is a synthetic, non-crystalline silica glass derived from silicon gas or silica sand (non-crystalline). It offers a very high transmission in the UV spectrum and can be either translucent or opaque. The purity of silica glass makes it useful in manufacturing semiconductor and laboratory equipment.

Momentive -Fused Quartz Use Guidelines

Heating fused quartz to elevated temperatures (ca. 2000°C) causes the SiO 2 to undergo dissociation or sublimation. This is generally considered to be: SiO 2 -> SiO + ½ O 2 . When flame-working fused quartz, there is a band of haze or smoke which forms just outside the intensely heated region.
