Economic Potential of Residual Deposits in Peneplanated Areas in Turkey

A peneplain is a geomorphological unit which is formed in the final stage of the fluvial denudational cycle. The developed peneplains on the bedrocks of containing iron, olivine, pyroxene, feldspar or feldspathoids comprise lateritic ore deposits. Besides the bedrock, the formation of this residual deposits arc due to both tropical climate and nonactive tectonic conditions. Today, actual lateralization has been going on in the climatic bells where tropical climate conditions are dominant in the world. But it isn't impossible to bring up that the lateritization has been lasting under actual climatic influences in Turkey. Paleoclimatological conditions in the geological past arc important for Turkey. For this reason, especially, the cycles of Upper Cretaceous and Lower to Middle Miocene in Turkey are suitable climatic cycles for lateritizations in Turkey, the relics of the oldest relief forms pertaining to Upper Cretaceous and the relics of "Anatolian Peneplain" pertaining to the denudational cycle of the Lower to Middle Miocene may be very interesting for residual ore deposits. When Turkey's tectonic evolution is appraised from this viewpoint: while the Pontides, the Anatolides, and Taurids in places appear to be the suitable belts, but not the Border Folds region. As a result, it isn't impossible to have enough knowledge about the residual deposits and their peneplanation cycles from the present surveys in Turkey. Consequently, the evolution of the residual deposits isn't known with details yet. For this reason, the prospection of the deposits must be planned by a multi-discipliner programme. Geomorphologically, the extent of the deposits must be mapped and their relations with the geomorphologic units must be explained.
