Take a look at an unusual combination of crystals and minerals
This is one of the items we have up on the Thursday thread but wanted to talk about it as these are really interesting.
These came from Guizhou, in China, an area they were mining fluorite. These specimens do have some fluorite, however the defining feature is these amazing included calcite crystals. I haven't been able to determine what the inclusions are yet but they give the calcite a really cool lodolite effect. The matrix is a basalt with quartz veins. Vugs have a fine quartz Druze with scattered, mostly small, clear or green fluorite cubes. The calcite occurs as a secondary growth with crystals sitting on either the quartz/fluorite or directly on fractured basalt.
