Autor: Luan Thanh PHAM, Erdinc OKSUM, Thanh Duc DO, Minh LE-HUY, Minh Duc VU, Vinh Duc NGUYEN

Publikováno v: Contributions to Geophysics and Geodesy, Vol 49, Iss 4, Pp 425-440 (2019)

In the evaluation of magnetic field data, edge enhancement and detection techniques are important treatments for the interpretation of geological structures. In general geological sense, contiguity of deep and shallow magnetic sources leads to weak a
