摘要
This paper describes a simple methodology for determining paleocurrent directions or fracture orientations from core that has traditionally been considered unoriented. Provided the core does not intersect bedding at a 908 angle, and that the attitude of bedding (strike and dip) and the drill hole (azimuth and inclination) are known, paleocurrent directions and fracture orientations can be determined in present-day geographic coordinates without the need for scribed core. This technique supplements dip-meter and borehole-image logs and allows the use of structures that are too small to be imaged geophysically.
