Title
A name given to the resource
(HA) Volcanic Phenomena Suite -- The Hawaiian Islands of Hawaii and Oahu
Description
An account of the resource
These 31 samples comprise a collection of volcanic rocks associated with the hot-spot volcanism of the Hawaiian Islands. Samples were collected from various locations across the islands of Hawaii and Oahu. The collection contains samples of primarily tholeiitic & alkalic basalts, pumice, scoria, oceanite, and hawaiite.

<ul><li>This article describes a study of lava flows from the 1955 eruption of the Kilauea Volcano on the island of Hawaii to evaluate models of crystal fractionation or magma mixing as the processes forming differentiated magmas.

Oceanite
Description
An account of the resource
Hand Sample: Aphanitic dark gray vesicular basalt with olivine crystals scattered throughout. The olivine crystals are most common in this sample than in other samples within the suite. Sample was collected from an olivine-rich zone within Mauna Loa flow.
Thin Section: Groundmass composed of mainly of glass, plagioclase, microcrystals of clinopyroxene. Thin section also contains phenocrysts of olivine and pyroxene.
