Faujasite
Faujasite is a mineral group in the zeolite family of silicate minerals. The group consists of faujasite-Na, faujasite-Mg and faujasite-Ca. They all share the same basic formula (Na

by varying the amounts of sodium, magnesium and calcium.[1] It occurs as a rare mineral in several locations worldwide and is also synthesized industrially. Faujasite was first described in 1842 for an occurrence in the Limberg Quarries, Sasbach, Kaiserstuhl, Baden-Württemberg, Germany. The sodium modifier faujasite-Na was added following the discovery of the magnesium and calcium rich phases in the 1990s. It was named for Barthélemy Faujas de Saint-Fond (1741–1819), French geologist and volcanologist.[3][4] Faujasite occurs in vesicles within basalt and phonolite lava and tuff as an alteration or authigenic mineral

Baden-Württemberg
Baden-Württemberg (/ˌbɑːdən ˈvɜːrtəmbɜːrɡ/,[5] German: [ˌbaːdn̩ ˈvʏʁtəmbɛʁk] (listen)) is a state in southwest Germany, east of the Rhine, which forms the southern sector of Germany's western border with France. It is the German state with the third-largest area, at of 35,751 km2 (13,804 sq mi), and the state with the third-largest population, at 11 million inhabitants.[6] Baden-Württemberg is a parliamentary republic and partly-sovereign federated state that was formed in 1952 by a merger of the young states of Württemberg-Baden, South Baden and Württemberg-Hohenzollern, which had just been artificially created by the Allies after World War II out of the existing traditional states Baden and Württemberg by their seperation over different occupation zones

Nepheline
Nepheline, also called nephelite (from Greek: νεφέλη, "cloud"), is a rock forming mineral in the feldspathoid group: a silica-undersaturated aluminosilicate, Na3KAl4Si4O16, that occurs in intrusive and volcanic rocks with low silica, and in their associated pegmatites. Nepheline crystals are rare and belong to the hexagonal system, usually having the form of a short, six-sided prism terminated by the basal plane. The unsymmetrical etched figures produced artificially on the prism faces indicate, however, that the crystals are hemimorphic and tetartohedral, the only element of symmetry being a polar hexad axis. It is found in compact, granular aggregates, and can be white, yellow, gray, green, or even reddish (in the eleolite variety). The hardness is 5.5 – 6, and the specific gravity 2.56 – 2.66

Lava

Lava is molten rock (magma) that has been expelled from the interior of some planets (including Earth) and some of their moons. Magma is generated by the internal heat of the planet or moon and it is erupted as lava at volcanoes or through fractures in the crust, usually at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F). The solid rock resulting from subsequent cooling is also often described as lava. A lava flow is a moving outpouring of lava created during a non-explosive effusive eruption. When it has stopped moving, lava solidifies to form igneous rock. The term lava flow is commonly shortened to lava

Olivine

. Thus, it is a type of nesosilicate or orthosilicate. The primary component of the Earth's upper mantle,[8] it is a common mineral in Earth's subsurface, but weathers quickly on the surface. For this reason, Olivine has been proposed as a good candidate for accelerated weathering to sequester carbon dioxide from the Earth's oceans and atmosphere, as part of climate change mitigation

Augite
Augite is a common rock-forming pyroxene mineral with formula (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al)2O6. The crystals are monoclinic and prismatic. Augite has two prominent cleavages, meeting at angles near 90 degrees. Augite is a solid solution in the pyroxene group. Diopside and hedenbergite are important endmembers in augite, but augite can also contain significant aluminium, titanium, and sodium and other elements. The calcium content of augite is limited by a miscibility gap between it and pigeonite and orthopyroxene: when occurring with either of these other pyroxenes, the calcium content of augite is a function of temperature and pressure, but mostly of temperature, and so can be useful in reconstructing temperature histories of rocks. With declining temperature, augite may exsolve lamellae of pigeonite and/or orthopyroxene. There is also a miscibility gap between augite and omphacite, but this gap occurs at higher temperatures

Kaiserstuhl (Baden-Württemberg)
The Kaiserstuhl (German: [ˈkaɪzɐʃtuːl] (listen), lit. "Emperor’s Chair") is a range of hills in the state of Baden-Württemberg in southwest Germany with a maximum height of 556.6 metres (1,826 ft).[1] It is of volcanic origin and located in the southwest of the state in the counties of Emmendingen and Breisgau-Hochschwarzwald. In terms of natural regions it is considered to be a part of the Upper Rhine Plain. The name "Kaiserstuhl" is believed to refer to King Otto III, who held court near Sasbach on 22 December 994. From then on, the whole hill range was called the Königsstuhl – the King’s Chair. In May 996, Otto III was crowned Emperor and the King’s Chair eventually became the Emperor’s Chair – "Kaiserstuhl"

Sodium Aluminate
Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO2, NaAl(OH)4 (hydrated),[2] Na2O·Al2O3, or Na2Al2O4. Commercial sodium aluminate is available as a solution or a solid.
Other related compounds, sometimes called sodium aluminate, prepared by reaction of Na2O and Al2O3 are Na5AlO4 which contains discrete AlO45− anions, Na7Al3O8 and Na17Al5O16 which contain complex polymeric anions, and NaAl11O17, once mistakenly believed to be β-alumina, a phase of aluminium oxide.[3][4] Anhydrous sodium aluminate, NaAlO2, contains a three-dimensional framework of corner linked AlO4 tetrahedra
