Labrador is located in the eastern edge of the Canadian Shield��where the U mineralization are vari- ous in type�� The most important mineralization is hosted in metamorphosed volcanic and sedimentary rocks��which is mainly distributed in Paleoproterozoic supracrustal rocks and intrusive rocks in the Central Mineral Belt (CMB) of Makkovik Province�� The mineralization types in this area are Magma type (pegmatite and acidic volcanic rocks)��Epigenetic- Hydrothermal type (some ones are similar to Fe oxide- Cu- Au (IOCG) type mineral depos- it)��Cut Tape type (may be the reason of metamorphism- accountable) and layered mineralization in sandy sedimentary rocks�� but the typical unconformity are not found�� On the base of mineralization types�� combining with ore- forming geological characteristics and mineralization geological data of deposits which have been found�� we can analyze and conclude that some of the metallogenic prospect areas have great exploration potential��and we can get the delineation of White Bear Lake and Nash Lake exploration strategy selection of U deposit��
