crystallography of Pyrite Marcasite on Lemonite matrix from PakistanThe Pyrite Marcasite on Limonite matrix from Pakistan is an extraordinary mineral specimen characterized by its unique crystallographic features and striking visual appeal. Pyrite, known for its metallic luster and pale brass yellow hue, often crystallizes in cubic or octahedral forms. In contrast, Marcasite, which shares the same chemical composition as Pyrite (FeS) but differs in crystal structure, typically forms orthorhombic crystals that exhibit
