对红层（盆）内外铀矿化的几点探讨

SOME DISCUSSIONS ON URANIUM MINERALIZATION IN AND OUT OF THE RED BED (BASIN)

Economic uranium mineralization exists in and out of the red bed (basin). Uranium mineralization out of the red bed includes various types such as the unconformity-related type, granite type, carbonate-siliceous-pelitic type, palaeokarst type, infiltration type and sandstone type, the formational process and distribution of which are closely related to the red bed (basin). It is by no means the protective layer of the unconformity-related uranium mineralization. The metallogenetic model and prospecting orientation for uranium mineralization out of the red bed are also summarized in this paper.
