contour line on map connecting points of equal stratigraphic thickness
Contour line Various geological data are rendered as contour maps in structural geology, sedimentology, stratigraphy and economic geology. Contour maps are used to show the below ground surface of geologic strata, fault surfaces (especially low angle thrust faults) and unconformities. Isopach maps use isopachs (lines of equal thickness) to illustrate variations in thickness of geologic units.
Military Demarcation Line The DMZ runs near the 38th parallel, covering roughly 248 kilometers (154Â mi).[4] American and South Korean soldiers patrol this line along the South Korean side while North Korean soldiers patrol along the North Korean side.
