Calcitgruppens

Calcitgruppens, also known as the calcite group, is a group of carbonate minerals that share a common crystal structure. The group is characterized by its trigonal-rhombohedral crystal system and its ability to form twin crystals. The calcite group is named after the most common member of the group, calcite, which is a calcium carbonate mineral. Other members of the calcite group include aragonite, vaterite, and ikaite. The calcite group is an important group of minerals in geology and mineralogy, as it provides insights into the formation and evolution of carbonate rocks and the processes that occur within them. The calcite group is also of interest to industrial and economic geologists, as some members of the group, such as calcite and aragonite, are used in the production of cement, lime, and other construction materials. The calcite group is a diverse and important group of minerals that continues to be the subject of ongoing research and study.
