Abstract Lineament field in a remotely sensed image is the reflection of geotectonic and geological minerlizing field on the surface of the earth and on the image, and is an indicator for geologic study and mineral exploration. From the point of view of the concepts of geological anomaly and lineament field, digital analysis methodes are discussed by using image processing techniques in the paper, and the digital analysis model are developed: (1) the calculating and diagramming of statistic features of lineament field; (2) digital presentation of the field; (3) mathematical analysis of the field. The lineament field analysis in Tongling Region was taken for an example to illustrute the application of the methodes to geological tectonic study and mineral prospecting.
