PRELIMINARY RESULTS IN THE DETECTION OF LINEAMENTS AND FRACTURES IN THE COMPARISON OF SKYLAB, ERTS AND FRACTURES IN PRECAMBRIAN

摘要

Lineament and fracture systems have been mapped for an area of about 9400n2 km in north-central Arizona, south of Flagstaff. The area investigated includes a part of the southern margin of the Colorado Plateau physiographic province and an adjacent structurally similar transition region that lies to the south. In the transition region, most of the nearly flat-lying Palecaoic strata have been removed, exposing a variety of Precambrian rocks and Precambrian structures.nMuch of the region is well known geologically, having been mapped by standard field techniques at scales of 1:62,500 and larger.
