What is a Porphyry Copper Deposit? - Arizona Geological Society
These minerals are disseminated throughout the rock and occur within and/or along the edges of veins cutting the rocks. Potassic alteration is characterized by the presence of quartz, potassium feldspar, biotite (dark colored mica) and anhydrite. It typically contains only minor amounts of chalcopyrite, pyrite (fool's gold) and molybdenite.

REE Analysis of Anhydrite Veins in Porphyry Copper Deposits
Anhydrite takes available divalent europium into its structure creating positive anomaly. At lower temperatures, further from the source, europium concentrations have been depleted resulting in a negative anomaly. This means that REE patterns in anhydrite can be used as exploration tools for tracking intrusions in porphyry mining districts.

Solution Mining Research Institute
SMRI views solution mining as mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water (not by using acids used in metal ore leaching). Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground caverns.

Cleveland & North Yorkshire Moors Iron Mining
There were various attempts to mine ironstone in the early nineteenth century, with ore being quarried on the coastal outcrops. The Pecten seam was discovered at Grosmont during the making of a cutting for the Whitby and Pickering Railway and the newly formed Whitby Stone Company sent a cargo of ironstone to the Birtley Iron Company in 1836.

Anhydrite is one of the major minerals in evaporite deposits; it also is present in dolomites and limestones, and as a gangue mineral in ore veins. It is used in plasters and cement as a drying agent. Anhydrite crystals possess orthorhombic symmetry. For physical properties, see sulfate mineral (table).
