pdf  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.
