The Origin of Minerals

Selected minerals are luminous when lit up by ultraviolet light. (foto F. Padovan)

     In the top part of Display case 42 the origins of some minerals are explained; in the middle part some crystals, some precious stones elaborated by man and natural elements such as copper, gold, silver and sulphur are displayed.
     On the bottom shelf a common feature of Alpago is demonstrated: calcium carbonate as deposited in the form of stalactites, stalagmites, travertine marble, alabaster, etc.

Crystallization of Minerals
     Drawings and written explanations show how crystals always take the same forms within the same micro-environment.
You can see here how to make a diamond from a pencil lead and viceversa. Samples of asbestos, haematite, fluorite, starolite, etc. are displayed.

Mineral Properties
     Various properties of minerals and crystals are shown, like hardness, elasticity, refraction, conduction, magnetism, etc. with rock samples to demonstrate these properties.
     The dark box containing some crystals in Display case 44 lets you make an interesting experiment: when you switch on the light they change colour.

     These wall panels illustrate the position of the glaciers in the Veneto during the last Ice Age and a classification of Igneous Rocks.
     There are also panels to illustrate oceanic troughs, mountain chains, the movement of the Continents, beginning 200 million years ago and predicting the position of the Continents 50 million years into the future.
