Geomorphological map of the southwestern Caspian Sea coast, compiled from field observations and 1980-1996 space images. Mountains: 1, denudation-erosion mountains; 2, denudation-erosion hills; 3, arid-denudation hills; 4, mud-volcano hills; 5, deluvial-proluvial washout slopes; 6, intermontane valleys. Plains: 7, abrasion-proluvial terrace (Q2-Q3); 8, abrasion-accumulation marine (Q3); 9, alluvial-proluvial submontane (Q3); 10, proluvial-deluvial submontane (Q3); 11, alluvial-lacustrine-deluvial (Q4); 12, lacustrine-solonchak (Q4); 13, alluvial (Q3-Q4); 14, delta (Q3-Q4); 15, accumulational marine (Q4); 16, accumulational marine, modern-day; 17, accretion. Subaqueous marine plains: 18, shallow-water active wave zone, and river-sediment flare distribution zone; 19, extreme coastal swell zone; 20, very deep area, below wave base. Coastal types: 21, erosional; 22, depositional. Relief forms: 23, fractures (lineaments); 24, ledges and sharp inclines; 25, mud volcanoes; 26, detrital cones; 27, erosion ridges, ravines; 28, old river beds; 29, uneven sands; 30, segments of modern-day coastal washout; 31, coastal barriers; 32, lagoons; 33, plumes of suspended material removed by rivers. [Editor's note on terminology: Deluvium refers to slope material, creep deposits, talus, etc., usually transported under periglacial conditions. Proluvium refers to mudflow and flash flood deposits of a bajada-type alluvial fan (Fairbridge Encyclopedia of Geomorphology, p. 678).]
