GEOLOGY MADE SIMPLE – DAY 1
GOLD AND PYRITE
The most confusing minerals to get you easily duped are gold and pyrite! Have you mistaken pyrite for gold before? Calm down if your answer is YES. It mostly happens that is why pyrite is nicknamed the Fool’s Gold-it takes professionals to unravel their differences.
1) Colour: Gold is metallic yellow in colour whiles Pyrite is brassy yellow in colour. Powdered gold remains metallic yellow but powdered pyrite is greenish black. Get a ceramic plate(streak plate) and scratch the mineral in hand on. If it leaves greenish black line or shade, then, the mineral is pyrite not gold.
2) Malleability: Gold has very soft edges because of its malleable nature but pyrite has sharp edges because of its brittle nature.
3) Reflectance: Gold maintains its shiny nature when dropped in water but Pyrite reduces its shiny nature when dropped in water.
4) Sparks: Gold does not sparkle when rubbed against hard surface but pyrite sparkles when rubbed against hard surface because of presence of sulphur which has pyro or fire properties.
5) Consult a professional Geological Engineer /Mineralogist like myself.
