The first finding of diatoms from the Early Miocene lacustrine deposits of the Barguzin Valley (Baikal Rift Zone)

Using light and scanning electron microscopy, we studied the species composition of diatoms and their distribution in the core hole 545 of the Barguzin Valley. We determined two local diatom zones that reflected the stages of the flora development in the Barguzin Valley during the Early Miocene.
