Title A name given to the resource (KBR) Karroo Igneous Complex -- Birds River, South Africa Description An account of the resource The Birds River Complex is a "Bell-Jar" intrusion first described by du Toit in 1905 and then by Ealey and Robey in 1976. One of the best exposed sections across the margin of the complex is on the farm Denwood, in the southwestern corner of the complex. The samples were collected from a mafic intrusion near Denwood farm. These samples from the Karroo Complex were collected from the previously studied section of the complex and neighboring areas.

Adinole is a dense rock of mostly quartz and albite formed as the alteration product of contact metamorphism. It is potassium-rich and has hercynite, a mineral that can occur in high-grade metamorphosed iron rich argillaceous sediments. This adinole is a medium grained, holocrystalline, hypidiomorphic-granular texture.There are gray crystals ranging from < 1 mm- 3 mm. It has a dusty red and yellow weathered surface. It has a vein of a very dark aphanitic material.There is a radiating structure present in thin section.

Title A name given to the resource (ADK) Anorthosite-Charnockite and Metamorphic Suite -- Adirondack Mountains, New York Description An account of the resource The Adirondack Mountains of northern New York State are underlain by approximately 20,000 square miles of complexly deformed, high grade metamorphic rocks which are believed to represent a southern outlier of the much larger Grenville Province.The Adirondacks can be divided into the "Lowlands" and the "Highlands" . The Lowlands comprise the northwestern quarter of the belt and are characterized by amphibolite facies metamorphism. The Highlands appear to consist entirely of granulite facies rocks. All rocks in this suite have been collected from the Highlands and predominantly from the southern quarter of the Adirondacks. This suite of rocks is designed to be representative of the Highlands in general. Therefore it includes both metasedimentary and metaigneous rocks. The latter are very common throughout the Adirondacks and contain the often-discussed anorthosite-charnockite suite of rocks. Almost all rocks in the Adirondack Highlands are strongly foliated. This is the result of intense polyphase deformation that has affected this area. Contributor An entity responsible for making contributions to the resource Western Minerals Inc.

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.

Date A point or period of time associated with an event in the lifecycle of the resource 1969 Identifier An unambiguous reference to the resource within a given context HA-1 - HA-31 Spatial Coverage Spatial characteristics of the resource. Samples were collected from various locations on the islands of Hawaii and Oahu. Temporal Coverage Temporal characteristics of the resource. Samples formed from Holocene eruptions of the past 300 years. Dated samples formed between 1750 and 1960. Accrual Method The method by which items are added to a collection.

Volcanic Phenomena Suite - The Hawaiian Islands of Hawaii and Oahu Description An account of the resource Hand Sample: Aphanitic dark gray vesicular basalt. Vesicles are common throughout sample and range in size from 0.1 to 3.5cm in diameter. Individual olivine crystals are found throughout the sample and range in size from 0.1 to 0.4cm in length. Thin Section: Groundmass dominated by plagioclase, glass and pyroxenes. Large phenocrysts of euhedral to subhedral olivine can be observed throughout the sample in addition to occasional vesicles.
