contents After death of benthic and planktic foraminifera their tests intensive dissolve in sediments of the upper sublittoral zone (depth 30-60 m) in the highest productivity area of surface water in the northern Peruvian region. Dissolution of fine pelitic ooze is more intensive than of sandy sediments. Rate of dissolution is lower in the lower sublittoral zone (60-200 m) than in the upper part of the zone. Within the upper bathyal zone (300-500 m) dissolution decreases and results to accumulation of carbonate test in this zone. Benthic tests are more abundant than planktic ones. Very poor species composition and a peculiar set of species are characteristic of foraminiferal assemblages found in the sublittoral and upper bathyal zones along the Peruvian coast.
