Inclusions can be a sort of fingerprint of the place of dicovery. Thus inclusions show us under which geologic conditions minerals had formed. This allows conclusions on the place of discovery. The article deals with the different kinds of inclusions, her conditions of build, which minerals do often have inclusions and how they appear. (Full text in german) |

The mineral calcite, however, differs from Aragonite due to its internal crystal structure. While the crystal system of calcite is trigonal, the system of aragonite is rhombic. Dense masses of small aragonite crystals are difficult to distinguish from calcite, but they are larger, they show a distinct habit. A lot of chapters in this portrait will give you much more details about this interesting mineral. Written and investigated by Peter Seroka. (Article in german) |
