Аннотация:The petrophysical database of effusive rocks including more than 4000 samples has been established at the Department of Engineering and Ecological Geology at the Moscow State University. The database includes samples of various age from different tectonic unites of the Earth and contains 20 petrophysical parameters as well as petrographical and mineralogical characteristics.
The alteration of effusive rocks properties have been considered in connection with various factors such as mineral composition and rock’s structure, age, tectonic. Main peculiarities of effusive’s properties formation and alteration have been described. The relationship between petrophysical properties has been studied.
