Based on Landsat MSS and RBV and other conventional data, total number of 1628 lineaments in Northern Korean Peninsula were extracted. Statistical analysis on the distribution of the extracted lineaments indicates the following characteristics. There are two prevailing direction in the orientation of the lineaments. i.e. one is from West-North-West to East-South-East while the other is from North-East to South-West directions which are considered due to the Shorin Metamorphosis in Triassic Period and Taiho Metamorphosis in Jurassic Period of Mesozonic Era. The most pronounced directions are 35°-215° followed by 285°-105° in azimuth angle. On the other hand the least prevailing direction is 315°-135°.The maximumun average length in 10 degrees class interval is, 22.6 km in the direction of 25°-205° while that of the minimum is 10.4 km in the direction of 335°-155°.
In case of 4 subdivided areas based on geologic characteristics, although the prevailing direction in general has a certain similarity to that of the whole area, the distribution of lineaments indicates a little difference in both prevailing direction, average lenght and density of the lineaments. The maximum and minimum densities of lineament distributions are found in the northern middle and the southern subareas with 16.6/10km2 and 10.3/103km2 respectively.
