Olivine Basalt

Olivine basalt is basalt with olivine phenocrysts. Phenocrysts are mineral grains that are substantially larger than the groundmass surrounding them. If the olivine grains are large enough they may be used as gemstones. Olivine as a gemstone is often named peridot(e). Olivine .

Basalt Wikipedia

Basalt commonly features a very finegrained or glassy matrix interspersed with visible mineral grains. The average density is g/cm 3 . Basalt is defined by its mineral content and texture, and physical descriptions without mineralogical context may be unreliable in some circumstances.

Basalt Rock Properties and Uses ScienceStruck

Most basalt rocks are primarily composed of the minerals pyroxene and feldspar. These rocks are formed due to lava flow. It is a type of rock that is abundantly found in the crust of the Earth, and although now found very commonly on land, most ocean floor areas are underlain with basalt that covers a large percentage of the Earth.

The South MidAtlantic Ridge is a typical slowspreading ridge that represents a modern example to understand mantle composition and the evolution of midocean ridge magmatism. In this paper, we investigate basalt samples dredged from four locations along the South MidAtlantic Ridge ranging from ° to °S. The basalts belong to the tholeiitic series and exhibit normal midocean ridge ...

In basalt. Tholeiitic basaltic lavas are characterized by calcic plagioclase with augite, pigeonite or hypersthene, and olivine (rarely) as the dominant mafic minerals; basalts without olivine are also well basalts, which contain 45 to 63 percent silica, are rich in iron and include the tholeiites..

About Basalt Hide. A general term for finegrained, mafic (darkcolored) igneous rocks, commonly extrusive (volcanic) but locally intrusive (, as dikes or pipes), composed chiefly of plagioclase and clinopyroxene; the finegrained equivalent of gabbro. Olivine and irontitanium oxides are very common and nepheline, orthopyroxene, or quartz may be present.

Where basalt has been quickly cooled, by contact with cold rock, a thin layer or selvage of black opaque glass is invariably present. Accessory minerals present in the basalts are ilmenite and magnetic ironore, in black opaque grains; apatite in colorless needles; and zircon, in conspicuous red grains.

Why Does Basalt Weather Faster Than Granite? | Hunker

Basalt is primarily made of the mineral oblivine, which has no cleavage or planes of weakness. The second most abundant mineral is pyroxene, which has 90degree cleavage and breaks easily. Plagioclase, which is typically light to dark gray in color, also has 90degree cleavage and a broken appearance due to fractures.

MINERALS IN IGNEOUS ROCKS

MINERALS IN IGNEOUS ROCKS. Regardless of their texture, igneous rocks commonly contain only a fairly small suite of silicate minerals, and very few nonsilicates. This page describes the few of the minerals common in igneous rocks. There are two major "unofficial" groups of minerals to watch for: ferromagnesian and nonferromagnesian minerals.

Dark primary igneous rocks (basalt, gabbro, and so on) are typically where olivine is found. The mineral usually occurs as small, clear olivegreen grains and stubby crystals. A rock made entirely of olivine is called dunite. Olivine is most commonly found below the Earth's surface.
