By J J FRANKEL DSc FGS AMIMM Department of Geology University of Natal Durban Taken as read 24 January 1957 Summary Metamorphosed dyke rocks in Witwatersrand gold mines carry pyrite crystals of unusual appearance These crystals particularly along th Pyrite (FeS) is one of the most widespread and persistent minerals and occurs in sedimentary, metamorphic, and igneous rocks.

Minerals form when molten materials cools and hardens inside the Earth or on the surface.. Sometimes minerals from when solutions with solutes evaporate.. MINERALS. Occur naturally and are inorganic solids (not alive).. By Jonah Winter . Fifth Grade . . Science. . Fool’s Gold vs. Gold. Talk to the students about prospecting for gold and how many miners were fooled by something that looks a lot like gold called pyrite. The students will work in small groups to compare samples of fool’s gold and real gold. They will use the attached worksheet to document their findings and make a prediction on which sample is the real gold. The class will reconvene to hear which indicators mean gold and which mean fool’s gold to check their prediction. . multispectral imaging. Sophie LEROY. G. . Dislaire. , P. Barnabé, . E. Pirard.
