Wizard101 is a 2008 massively multiplayer online role-playing game (MMORPG) developed and published by KingsIsle Entertainment.Players take on the role of student wizards who must save the Spiral, the fictional universe in which the game is set, from various threats.
The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), [6] or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .
Also, the mineral pyrite is both the most common and most abundant sulfide mineral in the Earth's crust. [6] If rocks containing pyrite undergo metamorphism, there is a gradual release of volatile components like water and sulfur from pyrite. [6] The loss of sulfur causes pyrite to recrystallize into pyrrhotite. [6]
Pirate101 is a 2012 massively multiplayer online role-playing game (MMORPG) developed and published by KingsIsle Entertainment.It is a sister game to Wizard101, set in the same fictional universe of the “Spiral”.
Marcasite reacts more readily than pyrite under conditions of high humidity. The product of this disintegration is iron(II) sulfate and sulfuric acid. The hydrous iron sulfate forms a white powder consisting of the mineral melanterite, FeSO 4 ·7H 2 O. [13] This disintegration of marcasite in mineral collections is known as "pyrite decay".
The group is named for its most common member, pyrite (fool's gold), which is sometimes explicitly distinguished from the group's other members as iron pyrite. Pyrrhotite (magnetic pyrite) is magnetic, and is composed of iron and sulfur , but it has a different structure and is not in the pyrite group.
Galena with baryte and pyrite from Cerro de Pasco, Peru; 5.8 cm × 4.8 cm × 4.4 cm (2.3 in × 1.9 in × 1.7 in) Galena is the main ore of lead , used since ancient times, [ 6 ] since lead can be smelted from galena in an ordinary wood fire. [ 7 ]
When deposits of arsenopyrite become exposed to the atmosphere, the mineral slowly converts into iron arsenates. Arsenopyrite is generally an acid-consuming sulfide mineral, unlike iron pyrite which can lead to acid mine drainage. [citation needed] The crystal habit, hardness, density, and garlic odour when struck are diagnostic.
