| Abstract: | The new data of classical goniometry and DIC microscopic observation are given. The morpholo-gy and surface microtopography of several silicate minerals are discussed, and the growth and dissola-tion spiral, a {100} on the the combination of grossularite, are described. A rather rare crystal draw-ing and DIC pictures of bertrandite show a classical type of 32 classes of symmetry, L2P. The surface spirals observed show the significance of spiral growth mechanism in the development of zircon, visu-vianite and bertrandite etc. |
