Abstract

Abstract

The Karoo Supergroup in Tanzania represent the earliest Phanerozoic deposition.The stratum is generally continuous, mainly formed in a series of half graben-graben basins that caused by rifting.Based on the comprehensive study of the regional geological distribution, lithologic composition, sedimentary environment analysis and the pollen biological characteristics,the sedimentary sequence, sedimentary facies and the age of sedimentation of each group, section of the Karoo supergroup are systematically studied.The ore-bearing characteristics of this stratum is summarized.According to the study, the lithology of the Karoo Supergroup in Tanzania is generally represented by a suite of sandstone-shale.The deposition time span is from the Late Permian to the Early Cretaceous, and the sedimentary environment from bottom upward is the glacial facies, lake facies and river facies.It is comparable to the typical Karoo Supergroup in South Africa.It also shows good mineralization potential of coal mines and sandstone-type uranium deposits; meanwhile, there are many oil and gas resources, graphite prospecting clues.
