Aesthetic small cabinet specimen with tabular to rhombohedral bronze-brown siderite crystals on a group of whitish translucent quartz crystals from the Muzo mining district in Colombia.<\/p>\n

Bronze-Brown Siderite on Whitish Quartz from Muzo<\/h3>\n

This mineralogically interesting small cabinet specimen shows a contrasting association of bronze-brown siderite and whitish translucent quartz from the Muzo mining district in the Colombian Department of Boyac\u00e1.<\/p>\n

The siderite crystals form a dense, prominent group at the upper end of the specimen. They are mostly tabular to rhombohedral and are partly intergrown in rosette-like aggregates. Their brown color with bronze highlights stands out clearly against the pale quartz crystals. <\/p>\n

In addition to the larger siderite group, smaller siderite crystals and aggregates are visible on other surfaces of the specimen. This allows the mineral association to be viewed from several angles. <\/p>\n

Aesthetic Siderite-Quartz Paragenesis from the Colombian Emerald District<\/h3>\n

Muzo is best known for its emerald deposits. The mineralization of the district is associated with hydrothermal veins and fractures in dark, organic-rich sedimentary rocks. In addition to emerald, various associated minerals occur there; quartz and siderite are documented from the wider Muzo area. <\/p>\n

The specimen has a slender, upright form. The concentrated siderite group creates a bronze-colored crystal cap on the pale quartz and gives the piece a clear contrast in both color and form. <\/p>\n

With dimensions of 5.7 \u00d7 2.8 \u00d7 1.5 cm and a weight of 33.2 g, this is a compact small cabinet specimen. Its main appeal lies in the clearly visible and aesthetic association of siderite and quartz from the well-known Colombian mining district. <\/p>\n
