The use of apatite fission track thermochronology to constrain fault movements and sedimentary basin evolution in northeastern Brazil
An apatite fission track study of crystalline rocks underlying sedimentary basins in northeastern Brazil indicate that crustal blocks that occur on opposite sides of a geological fault experienced different thermal histories. Samples collected on the West block yielded corrected fission-track ages f...
