WebIn solid state chemistry, the fluorite structure refers to a common motif for compounds with the formula MX 2. [1] [2] The X ions occupy the eight tetrahedral interstitial sites whereas M ions occupy the regular sites of a face-centered cubic (FCC) structure. Many compounds, notably the common mineral fluorite (CaF 2 ), adopt this structure. WebChlorite is very common, and is often an uninteresting green mineral coating the surface of more important minerals. However, there are some crystal forms and varieties that are attractive on their own right. Chlorite also forms as inclusion s within other minerals, especially Quartz, where it makes the host mineral green and may even cause ... ford recall vin check
