Rubidium: geological information. Rubidium is far too reactive to be found as the free metal in nature. It is relatively rare, although it is the 16th most abundant element in the earth's crust. Rubidium is present in some minerals found in North America, South Africa, Russia, and Canada. It is found in some potassium minerals (lepidolites, biotites, feldspar, carnallite), sometimes with caesium as well.
Also known as the boat orchid, Cymbidium (sim-BID-ee-um) hybrids descend from species originating mainly in the Himalayas, the mountainous regions of India and China. They can also be found throughout the Far East: through Japan, Philippines and Australia.lso known as the boat orchid, Cymbidium (sim-BID-ee-um) hybrids descend from species originating mainly in the Himalayas, the mountainous regions of India and China.
