A monoclinic mineral, Al<sub>2</sub>(SO<sub>4</sub>)(OH)<sub>4</sub>.7H<sub>2</sub>O ; pseudo-orthorhombic, formerly called websterite.
Industry:Mining
A monoclinic mineral, Al<sub>2</sub>(SO<sub>4</sub>)(OH)<sub>4</sub>.7H<sub>2</sub>O ; pseudo-orthorhombic, formerly called websterite.
Industry:Mining
A monoclinic mineral, Al<sub>2</sub>Si<sub>2</sub>O<sub>5</sub>(OH)<sub>4</sub>.2H<sub>2</sub>O ; kaolinite-serpentine group; soft, colorless to white; commonly tinted by impurities. (It is called halloysite in European literature.) Formerly called hydrated halloysite, hydrohalloysite, hydrokaolin.
Industry:Mining
A monoclinic mineral, Al<sub>2</sub>Si<sub>2</sub>O<sub>5</sub>(OH)<sub>4</sub>; kaolinite-serpentine group; differs from other kandites, such as triclinic kaolinite and monoclinic dickite, in the stacking order of its layers (polytypy); fine-grained, massive; commonly associated with hydrothermal alteration.
Industry:Mining
A monoclinic mineral, Al<sub>2</sub>Si<sub>2</sub>O<sub>5</sub>(OH)<sub>4</sub>; kaolinite-serpentine group; polymorphous with halloysite, kaolinite, and nacrite, each having a different stacking order of identical layers (polytypy); commonly in hydrothermal veins.
Industry:Mining
A monoclinic mineral, Al<sub>4</sub>(SO<sub>4</sub>)<sub>6</sub>.27H<sub>2</sub>O .
Industry:Mining
A monoclinic mineral, AlPO<sub>4</sub>.2H<sub>2</sub>O ; green; dimorphous with variscite.
Industry:Mining
A monoclinic mineral, AlVO<sub>4</sub>.3H<sub>2</sub>O ; weakly radioactive; forms coatings on highly weathered sandstones of the Colorado-Utah carnotite region.
Industry:Mining
