Web*Gravity driven domes and basins : In many non- orogenic areas, domes and basins have resulted from the active ascent of mobile rocks. Such domes and basins resemble structures that develop spontaneously in a system where a heavy fluid is laid above a lighter fluid. The geometrical analogy has led to the notion of diapirs.
