STRATIGRAPHIC SEQUENCE OF THE CRETACEOUS FORMATIONS AND THEIR PALEONTOLOGICAL SUBSTANTIATION IN THE KURGANCHA KEY SECTION (ZIRABULAK REGION)

According to the faunal complexes (foraminifers, bivalves, ammonites, gastropods), the Cretaceous deposits of the Zirabulak
Region are subdivided into stages, substages, formations and subformations. The identified stratigraphic units have acquired a
paleontological characteristic and are compared with the General Stratigraphic Scale of Uzbekistan, which is a reliable basis for
making legends to geological maps.
