Vertical component of the magnetic anomalies and, horizontal and vertical gradients are calculated by using the theoritical dike formula into which varying parameters resulting from different situation between depth and widthness of a dipping dike are submitted. Amplitude and phase functions associated with the dike are plotted through the values of the gradients. And also, as a result of these functions the conformity of the dike parameters are observed. A field application is added. The horizontal and the vertical gradients, 1which the later derived by means of Hilbert transformation are obtained by taken a c1 c;..l profile from a map of vertical component of the magnetic field which is belong to a dike in the area of Akc;akoca (Bolu). Result: All the paTameters of the dike are found from the gradients. In order to check validity of the method (the complax gradient) the calculated parametrical values of the dlk ~ from C1 <; profile were first put into the theoritical dike (AZ) formula; then, a comparison was made between the theoritical dike anomaly anu on the one of the map. It was observed that the two anomalies are quitesimilar ea.ch other.
