Various systems and methods for implementing an azimuthally sensitive resistivity logging tool are disclosed. One such method involves transmitting a primary magnetic field from one or more coils placed on a drill collar and receiving several electrical signals, where each of the electrical signals is received from a respective one of several sensors. The sensors are distributed around a circumference of a drill collar, and an axis of at least one of the sensors is perpendicular to an axis of the drill collar. Each of the electrical signals indicates a respective magnitude of a measurement of a reflected magnetic field, where the reflected magnetic field is reflected from an anomalous geological formation. The method calculates a vector measurement of the reflected magnetic field, based upon the electrical signals.
