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 is a part of the general investigation of the island of Hawaii by the United States Geologic Survey.

<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.

Title
A name given to the resource
Trachyte
Description
An account of the resource
Trachytes are an igneous volcanic rock with an aphanitic or porphyritic texture. Alkali feldspar, low amounts of plagioclase and quartz or a feldspathoid are common in trachytes.
Hand Sample: Aphanitic, light gray trachyte. On cut face, inclusions ranging from 0.8cm to 2cm in length with abundant vesicles less than 0.05cm in diameter can be observed.
Thin Section: Composed nearly entirely of glass material with some subhedral to euhedral plagioclase crystals that vary in size.
