METHOD OF LINEAMENT ANALYSIS Russian patent published in 1998 - IPC

FIELD: processing of aerocosmic survey data; prospecting of oil, gas and ore deposits. SUBSTANCE: lineament orientation sectors and bisecting lines of central angles of these sectors are determined on lineament diagram. Lineaments oriented in given sector are selected. Contours are drawn at right angles with central angle bisecting line through equal spaces. Cross-points of contours with lineaments are marked. Contour section and lineament sections corresponding to it are determined for every above- indicated point. Lengths of indicated contour sections are measured in succession on every contour, and graph of distribution of these lengths is plotted. Definite range of lengths on graph is suppressed. Contour sections lying in this range of lengths are found, and sections of lineaments corresponding to them are found and suppressed. EFFECT: lower noise level during geological plottings. 3 dwg
