Summary:

Lava flows of Pre-Waihu and of post-Pohakuloa are named "Liloe Formation" (oldest formation of Laupahoehoe Group, Mauna Kea Volcano, Island of Hawaii).

Summary:

Named "Liloe Formation" is here abandoned and formally applied to chronostratigraphic unit --"Liloen stage". Volcanic rocks are now assigned to Waikahalulu Formation of Laupahoehoe Group. K-Ar ages indicate 122,400 +/-7300 to 94,500 +/-6100 yr B.P.
