Significance of uniaxial and hydrostatic pressure studies on ancient oceanic rocks in tectonics
Uniaxial studies are carried out on Indus suture zone rocks of Kashmir Himalaya, which are supposed to be dismembered ophiolites. The percentage difference between the sonic and static determined Young's modulus varies from 4% to 25%. Serpentinite showed the lowest value of compressive strength (45 MPa) and pyroxenite gave the highest value (269 MPa), while meta volcanics exhibited narrow limits of 58 to 245 MPa. Standard correlations were obtained for compressive strength to G/P ratio and for compressive strength to tensile strength. Standard correlations for compressive strength to Young's modulus and compressive strength to maximum strain energy will bring out anomalous behavior, if any, of the different rock types, as well as the detection of weak zones. Compressional wave velocity measurements were carried out on alt the samples of the sequence up to 10 kbar pressure by simulating the similar hydrostatic pressure conditions of oceanic crust, since the rocks are supposed to represent the ancient oceanic crust (ophiolites). The relationship between the number of cracks/m to compressional wave velocity have been established. These results can be compared with the dredged samples of oceanic crustal rocks of other regions in drilling since these studies are carried out in the same pressure conditions.
