About QuartziteHide

This term usually infers a regionally metamorphosed quartz-sandstone, but the term is commonly also used as a field term for orthoquartzite (a sedimentary rock), secondary quartzite and paraquartzite.

i. A granoblastic metamorphic rock consisting mainly of quartz and formed by recrystallization of sandstone or chert by either regional or thermal metamorphism; metaquartzite. A granulose metamorphic rock consisting essentially of quartz.
Ref: Holmes, 1


ii. A very hard but unmetamorphosed sandstone, consisting chiefly of quartz grains that are so completely cemented with secondary silica that the rock breaks through the grains rather than around them; an orthoquartzite. Sandstone cemented by silica that has grown in optical continuity around each fragment. Cf: ganister
Ref: AGI
Ref: USBM, 7

iii. As used in a general sense by drillers, a very hard, dense sandstone.

Ref: Long
