Provinces deposited in the period between Late Archean and Early Proterozoic

The geotectonic position and main types of uranium provinces deposited in the period between Late Archean and Early Proterozoic are considered. They are the earliest provinces. Occurrence of potassium granites and pegmatites distinguishing by high uranium content has been a source of geologic premises for their advent. Comparative characteristics and peculiarities of South-African, South-Canadian, East-Brazilian, Fransvilian uranium provinces formation are given. Attention is paid to geologic premises for advent and criteria of prediction of uranium provinces deposited in the period between Late Archear and Early Proterozoic
