Mg–Fe carpholites from aluminous schists in the Diahot ...

Abstract Mg–Fe carpholite is widespread in the Diahot region of New Caledonia in highly aluminous schists and as veins in what was originally a clay-rich hydrothermal alteration envelope about massive suphide deposits. These carpholites have Fe/(Fe + Mg) ratios of 0.03–0.65 and no significant Mn component. Mg-carpholite + quartz occur in assemblages with chlorite or pyrophyllite ...

CLAY MINERALOGY AND CHEMISTRY OF HALLOYSITE AND …

A field-mapping and crystal-chemical study of two alunite- and halloysite-rich deposits in the Turplu area, situated northwest of Balıkesir on the Biga Peninsula of northwest Turkey reveals a mineralogically diverse and a potentially economic clay deposit. The mineral assemblage along fault zones is dominated by halloysite and sometimes alunite.

Clays Statistics and Information - USGS.gov

Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types. Major domestic markets for these clays are as

CiteSeerX — The origin of high-alumina clay minerals-a review

Apparently aluminous gels were formed within certain marshy basins, and/or were transported into basins, giving rise to concretionary masses of high-alumina minerals. Concretionary deposits were iormed by dissolution of A1 and reprecipitation. Alumina is probably more soluble, inherently, than is interpreted from geologic occurrences.

A unique aspect of martian geology is the presence of similar compositional stratigraphy observed in many locations throughout the surface. Where the Al-rich and Fe/Mg-rich clay minerals occur together, aluminous clays typically overly layered ferromagnesian clays, possibly indicating that precipitation-driven leaching occurred in a warmer, wetter climate.

Aluminum processing - Ores | Britannica

Aluminum processing - Aluminum processing - Ores: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
