Abstract
The Sebaco depression of the strike-slip origin is build up of Tertiary andesites and ignimbrites. The Quaternary infill (loams, silts, redeposited tuffs and fluvial sands with gravel interbeds) is 80-100 (max. 140 m) thick.Younger alluvial fans composed of sand and gravel developed around the entrances of the mountain streams into the depression and are over 10-15 m thick (vicinty of Sebaco and La Trinidad). Fluvial and slope sediments of small thickness and regional extent occur in place.
