Thirty-six typical REE deposits extracted from literatures,mineral resource database or reports,which are served as a basis for classifying deposit type.And then the five principal deposit types were identified:(1)alkali-related type;(2)Ion-adsorbed type;(3)metamorphosed sedimentary type;(4)placer type;(5)sedimentary phosphate type.Data gathered for each deposit includes the deposit scale,geologic settings,main metallogenic ages,main and accessory minerals,and ore-bearing intrusions.
