| Pre-Patom trough - lithology of the Upper Riphean – Lower and Middle Cambrian terrigenous-carbonate complex | |
| The petrographic and lithogenetic peculiarities of the Riphean and Lower-Middle Cambrian deposits of the Pre-Patom trough are analyzed. The objects of study in the Pre-Patom trough are deposits in outcrops of the Nokhtuysk (Lena River) and Bolshe-Patom (Bolshoy Patom River).
Particular attention is paid to the diagenetic transformation and evaluation of reservoir properties of the studied rocks. Diagenesis did not lead to a significant increase of effective porosity. The correlation between composition and structure of Nokhtuysk and Bolshe-Patom sequences is set. The dynamics of changes in lithological parameters in the Vendian-Cambrian period are reflected in the sequence of sedimentary carbonate strata. Key words: petrographic composition, lithogenetic type, Riphean, Vendian, Cambrian, sedimentation conditions, post-sedimentation transformation, reservoir, Pre-Patom trough. |

| Genesis conditions of the Riphean-Lower Cambrian sand and pelitic rocks in petroleum potential evaluation of Pred-Patom foredeep | |
| Oil and gas potential of the Riphean-Lower Cambrian strata in the central and eastern parts of Pred-Patom foredeep was evaluated using analytical study of sedimentation environments, composition and reservoir properties of terrigenous rocks, minerals and sealing features of pelitic rocks. Dynamo-genetic diagram was constructed as a result of cumulative curves’ correlation. Preliminary information on the sedimentation conditions of terrigenous rocks was obtained. Marine and coastal facies are identified. Mineralogical study of pelitic rocks was conducted. Capacitance-filtration properties of terrigenous and pelitic rocks were evaluated.
Key words: Pred-Patom foredeep, grain composition, mineral composition, facies, sedimentation conditions, Riphean, Vendian, Lower Cambrian. |
