Physical properties (elastic anisotropy and density) of rock samples of the Jarva-Varaka massif (Monchegorsk area)
The physical properties (density, elastic anisotropy) of a collection of rock samples with signs of shock metamorphism sampled from the surface in the layered Jarva-Varaka massif area (within the boundaries of the supposed astrobleme) were investigated. Significant areal variations in the elastic anisotropy index and the correlation of rock density with the velocity of ultrasonic longitudinal waves were established. A number of «anomalous» unconformities were identified in the studied physical properties of studied rocks with similar properties of rocks from other areas of the NE Baltic Shield.
