The quartzites and mica schists are predominantly composed of quartz, plagioclase, microcline, muscovite and chlorite in varying proportions, with biotite, garnet and epidote in mica schist. The rocks have quartzose sedimentary composition and plot within the passive margin setting on major element discrimination diagrams.

The mineral composition of quartzite is predominantly quartz (quartz content in the rock reaches 88-98%), with iron hydroxides (2-3%), silicon and chalcedony (4-5%). The stone also contains impurities of mica, talc, feldspar, and other minerals.

Samples were taken at 0–15 cm, 15–30 cm and 60–90 cm at 15 m interval from the crest to the valley bottom of two toposequences, one on quartzite schist and the other on banded gneiss within the same microclimate. Variations in pH, colour, (hue, value and chroma) particle size fractions, gravimetric moisture, gravel and CEC were examined. Soil pH was …

Résumés English Français Bien que les paysages développés sur quartzite au Brésil s'étendent sur de grandes surfaces, les connaissances sur les processus et les mécanismes impliqués dans leur formation sont peu avancées. Des recherches récentes ont identifié des signatures karstiques associées à la dissolution de la silice.

This work thus determines the industrial uses of the quartzite waste materials from the tungsten ore mine in Zumba, North central Nigeria, using mineralogical, physical and mechanical properties. Quartzite is a metamorphic rock which is hard, non-foliated and is made up mostly of the mineral quartz.

The term quartzite implies not only a high degree of hardening (induration), or "welding," but also a high content of quartz; similar rocks that contain appreciable quantities of other minerals and rock particles are impure …

Quartz-sulfide veins and gneisses are the two main types of gold mineralization. The gold-quartz-sulphide veins rarely run deeper than a few tens of metres.
