Quaternary Research,
52: 14-26
Holocene glacial deposits in Sredniya Avacha headwaters are
subdivided into three age groups (events A, B, and C) based upon
geomorphic features, tephrochronology, and lichenometry. Tephras
of Opala volcano (1400–1500 yr B.P.), Ksudach volcano
(1700–1800 and 6000 yr B.P.), and Zavaritskiy volcano (2800 yr
B.P.) are used as stratigraphic markers. Rhizocarpon geographicum
(L.) DC and Rhizocarpon section Alpicola growth curves are
established using tephrochronologically dated and historical …
