Tephrostratigraphic dataset from the Pestani site, Lake Ohrid

Tephrostratigraphic dataset of the Pestani site, Lake Ohrid. The dataset includes information about position (core, core section depth, depth in composite succession), appearance (thickness), age and glass geochemical composition (major, minor elements) of 31 tephra layers identified in the Pestnai site sediment succession from Lake Ohrid. Equivalents of individual tephra layers identified in the DEEP site from Lake Ohrid are given along with the proposed volcanic origin and identified eruptions.
