Siderite on Quartz - GeoKrazy Minerals

I tend to fall for classic or unusual Mexican specimens and this one had that eye appeal for me. Two smoky quartz intersect each other and one appears to have growth interferance as the face is complete yet the growth was stunted. The entire back of the piece is completely coated with siderites and the front has an ever so slight dusting of siderite adding a sparkle.

Siderite - Wikipedia

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite …

For instance, let's say you have nice Barite crystals, but they are embedded and covered over by Calcite. From the tables below you would find that Calcite dissolves readily in Hydrochloric Acid, but Barite is unaffected by it. So that acid could be used to etch away the Calcite, exposing the Barite crystals.
