The magnesite deposits are in pre-Cambrian crystalline limestone. They were formed by replacement of the calcium in limestone or dolomitized limestone by magnesium, which probably was carried by hypogene solutions. The resulting bodies are massive and lenticular, and consist of fine-grained to coarse-grained crystalline magnesite.
