Syneclise

Syneclise

 

a very gently sloping depression in the earth’s crust within a platform. The structure has irregular roundish or oval contours; diameters range to several hundred km and sometimes exceed 1,000 km. Depths are usually 3 to 5 km. Syneclises are formed over a long period of time (hundreds of millions of years), with comparatively minor changes in contour. Sediments are thicker and geologic columns are more complete at the center of a syneclise than at the periphery, where the columns are characterized by numerous hiatuses in sedimentation. Syneclises often develop over aulakogenes and often consist of separate depressions complicated by arches.
