Orange ferruginous quartz and quartzite are both natural silicon dioxide
rocks colored orange by iron oxide, but differ in their formation and structure.
Ferruginous quartz refers to a variety of quartz crystals with orange to
red colors from iron inclusions like hematite or limonite, which can be
either within the crystal or on its surface. Ferruginous quartzite,
a type of sandstone, is a more metamorphosed, harder rock where
the quartz grains are cemented together by hematite, resulting in a dark,
often blood-red color and a brittle structure.
