From Plate Tectonics to Gemstone Formation
Speaker: Ms Trudy Kwong
Plate tectonics is a theory that explains the structure of the Earth’s lithosphere and its associated geological phenomena. The relative plate motions create earthquakes, volcanic activities, and mountain belts along the plate boundaries. They are also directly related to the formation of gemstone deposits all over the world.
This talk will discuss the geological origin of common gemstones (jadeite, ruby, sapphire, and diamond), their tectonic settings, distribution, and geological significance.
