These massifs aggraded in response to tectonic subsidence, forming prominent positive relief features on the ocean floor. Repeated sea level oscillations led to periodic subaerial exposures and associated karstification, while meteoric-marine mixing in their margins led to dolomitization. Together, these processes generated extensive karst voids and secondary porosity that later served as hydrocarbon reservoirs. Subsequent fold-and-thrust deformations and orogenesis, uplifted and exposed giant fragments of carbonate massifs, enabling detailed stratigraphic and sedimentological investigations, which provide valuable insights for geological exploration across the sedimentary basins of Central Asia.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>sedimentary basin</kwd><kwd>carbonate</kwd><kwd>aggrading-up sequences</kwd><kwd>hydrocarbon</kwd></kwd-group><kwd-group xml:lang="kk"><kwd>шөгінді бассейн</kwd><kwd>карбонаттар</kwd><kwd>жоғары қарай аградациялық түрде дамыған сиквенстер</kwd><kwd>көмірсутектер</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>осадочный бассейн</kwd><kwd>карбонаты</kwd><kwd>аградирующие кверху сиквенсы</kwd><kwd>углеводороды</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Жемчужников В.Г., Ергалиев Г.Х.
