Materials that are commonly calcined include phosphate, aluminum oxide, manganese carbonate, petrol coke, and sea water magnesite. |
Calcite and ankerite are present, but the most abundant carbonate is magnesite. |
Some topaz forms spectacular crystals and matrix specimens on magnesite or quartz. |
A home made lick can be made by mixing molasses and calcined magnesite in equal parts by weight. |
The most distal alteration is volumetrically minor and involves alteration of olivine to antigorite and magnesite. |
Associated with the quartz are crystals of almandine, kyanite, biotite, and magnesite. |
