Pyrite is often called "fool's gold" because of its shiny, metallic look. But there's much more to this mineral than meets the eye, with several fascinating types of pyrite waiting to be explored. In the world of geology, pyrite stands out for its variety, including forms like octahedral pyrite, Navajún pyrite, and pyrite suns.
Pyrite is a common accessory mineral in sedimentary rocks, particularly in limestone, sandstone and carbonaceous siltstones or shales. Some times we wonder who and why it got there; and what does it mean for petroleum exploration. Originally the iron came from the weathering of older igneous or metamorphic rocks.
Pyrite. Mineral Type: No Cleavage. A metallic mineral that is pale brass-yellow in color, has 3 cleavage planes forming perfect cubes, produces a brown-black streak, has a hardness of 6.5 and a specific gravity of 5.0.
Pyrite-pyrrhotite ratios change during metamorphism as prograde heating results in sulphur release from pyrite to form pyrrhotite and as retrograde cooling permits re-growth of pyrite as the pyrrhotite releases sulphur. Retrograde growth of pyrite may encapsulate textures developed during earlier stages as well as preserve evidence of ...

Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS 2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear indicators exists. Pyrite's structure is analogous to galena's structure with a formula of PbS.

This pyrite could be an indicator of primary organic matter concentration on the base of bacterial chemosynthesis from CH 4-seepage activity in the Jurassic. Framboidal pyrite, formed due to interaction with organic matter, is enriched in redox-sensitive elements such as Mo, V, Au, Cu, Pb, Ag, Ni, Se and Zn in comparison with the …

Pyrite is much more commonly known in laymans terms as fools gold. This is because, when gold mining was popular, pyrite could often be mistaken for gold due to its shining gold exterior. Of course, they are actually quite different minerals, but to the untrained eye, the mistake could be an easy one to make. In the past, pyrite was used …
L'or des fous est un terme attribué à un minéral communément connu sous le nom de pyrite. Nous devons cette appellation à la grande ressemblance avec l'or, tant au niveau de la couleur, de la brillance ainsi que de la forme. À l'époque de la ruée vers l'or, beaucoup de gens se mirent à la recherche de ce minéral doré et parmi ces ...

Pyrite Pyrite, also known as "Fool's Gold" because of its brassy-yellow metallic colour, is the most common sulphide mineral in rocks of all ages, being found in virtually every geological environment. It is easily distinguishable from gold as it has a lower specific gravity (specific gravity of gold is 15.9-19.3) and it is harder (hardness of gold is 2.5-3).
