... Abstract In this study; for a copper mine located in the north of Turkey, the strength of the effect of anisotropy properties of metamorphic rock composed of mica-schist and greenschist was investigated. For this purpose, for core samples which have foliation planes taken as 0°, 15°, 30°, 45...

The seismic radial anisotropies at these two sites show a strong...

... ABSTRACT Fracture prediction has a very important practical significance in study of metamorphic rocks reservoir. In this paper, the fracture prediction method and the tectonic stress field simulation principle are discussed. In the process of trend surface fitting, the original 3×3 grid...

Compared with contemporary tensile tests, this method is relatively simple and effective, with easy specimen preparation. Besides, this approach can be conducted not only in the laboratory but also in the field, which...
