Amesite

A species of Minerals, Also known as Amensite, Magnesium kaolinite

Amesite is a mineral with general formula of Mg2Al2SiO5(OH)4. Amesite crystallizes in the triclinic crystal system. It contains three axes of unequal length, not at right angles. It was first described in 1876 for an occurrence in the Chester Emery Mines, Chester, Hampden County, Massachusetts. It was named for mine owner James Ames. It occurs in an environment of low-grade metamorphism affecting rocks with high aluminium and magnesium content. It occurs associated with vesuvianite, chlorite, magnetite, rutile, diaspore, grossular, calcite, diopside and clinozoisite in various locations. Amesite is an uncommon silicate mineral which has been reported from a variety of locations worldwide. Amesite has the first reported natural occurrence of the 6R polytype for a trioctahedral 1:1 layer silicate.

Pitchstone

Pitchstone is a glassy volcanic rock, similar to obsidian, but duller and with somewhat waxy luster due to its high water content. The material is found only in Colorado, USA, and on Arran Island, which is off the coast of Scotland. It is believed that this rock was was used on the Aran Island from the Mesolithic to the Bronze Age, from where it was later transported to other parts of Britain.

Hanksite

Hanksite is a sulfate mineral, distinguished as one of only a handful that contain both carbonate and sulfate ion groups. It has the chemical formula Na22K(SO4)9(CO3)2Cl.

Serendibite

Serendibite is an extremely rare silicate mineral that was first discovered in 1902 in Sri Lanka by Dunil Palitha Gunasekera and named after Serendib, the old Arabic name for Sri Lanka. The mineral is found in skarns associated with boron metasomatism of carbonate rocks where intruded by granite. Minerals occurring with serendibite include diopside, spinel, phlogopite, scapolite, calcite, tremolite, apatite, grandidierite, sinhalite, hyalophane, uvite, pargasite, clinozoisite, forsterite, warwickite and graphite.
