Geological Mapping

Mr. Berry has experience of mapping in all environments from tropical jungles to deserts to sub-polar regions, and also in rocks of all types from late Tertiary sediments and volcanics to Precambrian igneous and metamorphic rocks.

He has mapped in the field in Zambia, Ethiopia, Brazil, the eastern and western United States, and Australia. He has done geological mapping using remote sensing, with limited ground follow-up, in Algeria, Australia, Brazil, Colombia, western China, Namibia, Pakistan, Papua-New Guinea, Yemen and many other countries.

One of Mr. Berry’s areas of special expertise lies in mapping highly weathered terrains in humid tropical environments such as Zambia, NE Australia, the southern Appalachians, and central Brazil. In these areas of minimal outcrop, mapping often depends on the accurate interpretation of the ‘C” horizon or saprolite. When the terrain is flat it is often necessary to create outcrop by means of pitting and trenching.

Another area of great interest is in mapping thrust and fold belts such as those of the southern Appalachians, the Tien Shan, the Sulaiman and Salt Ranges of Pakistan, the Mayan ranges of southern Mexico, the Colombian Andes, the Lufilian arc of central Africa and the correlative Bambui fold belt of central Brasil. In these areas remote sensing techniques can be of great assistance, but the detailed study on the ground of critical localities is often key to understanding the overall picture.
