Background

Maly Payalpan is a small late-Quaternary Icelandic-type shield volcano that is dwarfed by its massive neighbor to the SW, Ichinsky volcano. Unnamed andesitic lava domes of uncertain age are located to the south of 1802-m-high Maly Payalpan. Maly Payalpan (Little Payalpan) is of basaltic-andesite to andesitic composition and was constructed on top of a late-Pliocene to early Pleistocene alkaline basaltic plateau. Youthful basaltic cinder cones of late-Pleistocene to possible Holocene age overlie Maly Payalpan. Early geologic studies in the Sredinny Range (Ogorodov et al., 1972) identified numerous Holocene eruptive centers based primarily on morphological criteria. However, later work has suggested that Sredinny Range volcanoes are less mantled by Holocene tephras than eastern Kamchatka volcanoes and therefore appear more youthful, so that Holocene eruptions are uncertain for many of these Sredinny Range eruptive vents.
