Reactions occurring during the heating of pyrite depend on the atmosphere. Fe2O3 is formed under good oxidizing conditions; FeS is formed when the atmosphere is low in oxygen. This is shown by DTA, X‐ray diffraction, and total sulfur determinations on iron sulfides, on their mixtures with illitic clays and inert materials, and particularly on shales ...

PYRITES (FeS2) in the form of small crystals and specks of a brassy-yellow colour may be found frequently in quartz. Four pieces of Brazilian quartz, containing pyrites inclusions, have now been found which are of unusual interest.
