Plutonic and Volcanic Basic Rocks Non-Destructive Study

摘要

Increasing interest of the modern industry to cheaper row materials, which could be used directly without additional or with small transformation (just cutting, forming etc.) makes us to study physical properties of industrial minerals. An interesting object in this way are the plutonic and volcanic basic rocks from the Eastern Srednogorie, Bulgaria. Traditionally their investigation includes chemical and mineral composition determination. For the industry much more interesting are their physico-mechanical properties. In the rare cases when they are define, the destructive methods are used. Interpolation of these scare data to huge rock massifs leads to significant mistakes. The physical properties of the rocks from the same petrographic type vary a lot. Non-destructive methods are cheaper and wide applicable. They have significant advantages compare to the destructive methods that are: the investigated object do not change its properties and whole? Could be conducted directly on the field; and the measurements need (take) short time. They are used for the continues control and direct production characterization.
