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.
Oct 23 2020 RESULTS At the ridgelines of the shale watershed most pyrite oxidation occurs within a 1 m thick reaction zone ∼16 m below land surface just above the depth of water table fluctuation This is the reaction front at the borehole scale Only limited oxidation occurs in halos around a few fractures at deeper depths.

Sep 02 2019 Laboratory testing on similar defects in Counties Mayo Donegal revealed the presence of muscovite mica and / or pyrite within the constituents of the concrete blockwork These naturally occurring minerals when exposed to moisture oxygen expand via a chemical reaction resulting in deterioration of the block These materials are deleterious
Pyrite and pyrrhotite are minerals known as iron sulfides When iron sulfides are exposed to water and oxygen a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates These sulfates take up more space than the original iron sulfides As they grow the new sulfate minerals push against the surrounding rock causing it to swell and crack.

Pyrite is more commonly known as fool's gold and is familiar to nearly every mineral collector It has been used for centuries both in jewelry and as an ore of iron Marcasite stones in jewelry are frequently pyrite since the latter is more stable The material is very brittle and heat sensitive and requires some care in cutting.

What is Pyrite Pyrite or Iron Pyrite FeS2 is a very common mineral that is present in many sedimentary rocks as framboidal crystals Subject to certain conditions pyrite is problematic in confined construction such as under floor filling and bridge embankments This is due to a chemical reaction that can cause pyritic backfill to swell.

pyrite noun a common mineral that consists of iron disulfide has a pale brass yellow color and metallic luster and is burned in making sulfur dioxide and sulfuric acid.
This swelling is produced by the reaction of pyrite with water air and moisture The swelling can cause star cracks and even lift the concrete slab In a garage given the greater presence of backfill material its effect may be more important to make lateral thrusts on the foundation walls of the house which is rather rare in a basement

Pyrite is a powerful protection stone that works on the physical etheric and emotional levels to shield and protect from all types of bad vibrations and/or energy It stimulates the mind and improves memory making it easier to recall important information when needed.
Pyrite oxidation begins with the oxidation of sulfur by oxygen yielding sulfate ferrous iron and acidity The rate limiting step is the oxidation of Fe 2 to Fe 3 which occurs only very slowly at low pH chemically but is catalyzed by bacteria that speed up the reaction rate by a factor of 100 000 Once underway the process of pyrite oxidation may continue until the source is exhausted.
