Dogtooth spar is a speleothem that consists of very large calcite crystals resembling dogs' teeth. They form through mineral precipitation of water-borne calcite. Dogtooth spar crystals are found in caves, open spaces including veins and fractures, and geodes. The crystals are generally centimeters long, but anomalous samples decimeters long exist, notably in Sitting Bull Crystal Caverns. A layer of crystalline calcite can be found underneath the surface of crystal points. Spar is a general term for transparent to translucent, generally light-colored and vitreous crystalline minerals.

  • La calcita espàtica és un tipus d'espeleotema consistent en microformes que creixen i es desenvolupen per davall del nivell de l'aigua dins els gours, en condicions de sobresaturació que provoquen la precipitació del carbonat de calci, però també poden créixer just arran d'aigua on hi ha un escapament de diòxid de carboni més immediat. Les cristal·litzacions subaquàtiques que es generen, folrant l'interior dels gours, produeixen superfícies rugoses de tipologia prou diversa, entre les quals no és difícil de trobar grans cristalls de calcita, de vegades molt ben desenvolupats. Hi ha exemples de cristal·litzacions d'hàbit romboèdric a més de cristalls de calcita d'aparença escalenoèdrica. (ca)

  • Dogtooth spar is a speleothem that consists of very large calcite crystals resembling dogs' teeth. They form through mineral precipitation of water-borne calcite. Dogtooth spar crystals are found in caves, open spaces including veins and fractures, and geodes. The crystals are generally centimeters long, but anomalous samples decimeters long exist, notably in Sitting Bull Crystal Caverns. A layer of crystalline calcite can be found underneath the surface of crystal points. The crystals typically consist of acute scalenohedrons, twelve triangular crystal faces that ideally form scalene triangles. However, modification of these faces is common, and some may have many more than three edges. Calcite crystallizes in the rhombohedral system, and the most common scalenohedron form has the Miller index [2131]. Spar is a general term for transparent to translucent, generally light-colored and vitreous crystalline minerals. (en)
