Chalcolithic Age = Beginning of copper age.

Some Confusion.
"The literature of European archaeology generally avoids the use of 'chalcolithic' (they prefer the term 'Copper Age'), while Middle-Eastern archaeologists regularly use it. The Copper Age began much earlier in the Middle East, while the transition from the European Copper Age to its own full-fledged Bronze Age is far more rapid."
