Quartz (trigonal, low-temperature α-quartz) is the most important polymorph of the silica
(SiO2) group and one of the purest minerals in the Earth crust. The mineralogy and mineral …

As a mineral resource, due to its stable physical chemistry properties, quartz has a wide
range of uses, such as silica glass, silica ceramics, silicon metal in the semiconductor field …

Titanium is one of many trace elements to substitute for silicon in the mineral quartz. Here,
we describe the temperature dependence of that substitution, in the form of a new …

Quartz and rutile were synthesized from silica-saturated aqueous fluids between 5 and 20
kbar and from 700 to 940° C in a piston-cylinder apparatus to explore the potential pressure …

Rutile is an important carrier of high field strength elements (HFSE; Zr, Nb, Mo, Sn, Sb, Hf,
Ta, W). Its Zr content is buffered in systems with quartz and zircon as coexisting phases. The …

The porosity and permeability of sandstone and carbonate reservoirs (known as reservoir
quality) are essential inputs for successful oil and gas resource exploration and exploitation …

Investigations of mineral textures and zoning as evidence for open system processes during
magmatic evolution have always been a centerpiece of petrological studies and have …

Luminescence from quartz is commonly used in retrospective dosimetry, in particular for the
dating of archaeological materials and sediments from the Quaternary period. The …

Quartz is one of the most abundant minerals in the Earth's crust and the most important silica
mineral, occurring in large amounts in igneous, metamorphic and sedimentary rocks. The …

Pegmatite quartz from different occurrences in Norway and Namibia was investigated by a
combination of ICP-MS, Electron Spin Resonance (ESR), Capillary Ion Analysis (CIA) and …
