The Landsat and SLAR images of exposed Precambrian crystalline crust ([[:file:using-magnetics-in-petroleum-exploration_fig14-4.png|Figure 1]]) show highly lineated terrains and demonstrate that the linears fall into multiple parallel or subparallel sets of varying strike directions. These overlapping [[fracture]] sets cut the basement into blocks of varying shapes and sizes. This collection of basement blocks is the '''basement fault block pattern'''.
