During an European (Italian, Portuguese, German) speleological project 3,5 km of cave passages were explored in the Cheringoma plateau north of the port of Beira, Mozambique. The karst is developed in Eocene limestone.
The most significant findings were deep karst canyons of Quaternary age, partly with rock ceilings creating caves (e.g. Codzo River Cave, 942 m long) and an older generation of caves filled with sediments which were outwashed by surface water during recent times (e.g. Western Codzo Cave, 612 m long).
Many caves were used for digging bat guano during colonial times.
