Новые геологические данные и зональное расчленение опорного разреза неокома на р. Ятрия (Приполярное Зауралье) по белемнитам, диноцистам и палиноморфам
Data on geological structure, zonal subdivision, and correlation of the Neocomian key section at the Yatriya River (Polar Transuralia) are reported. Autonomous scales have been developed according to belemnites (five stratons ranked as zones and beds with belemnites), dinocysts (five beds with dinocysts), as well as spores and pollen (three palynocomplexes).
