Basalt rock's upper crystallization limit temperature from different deposits depends on basalt's chemical makeup and lies within the temperature range of 1215–1280 оС, while the melt's temperature is kept of about 1500–1600 оС. The properties of mineral (including basalt) fiber are characterized by two macro indicators: the

Basaltic rocks are an abundant lithology in Hole U1362A. The recovered core consisted of (1) aphyric to moderately phyric pillow basalt, (2) aphyric to sparsely phyric sheet flows, and (3) sparsely to highly phyric basalt flows (Tsuji et al. 2010; Fisher, Tsuji, et al. 2011). The pillow basalt varies from sparsely to highly phyric basalt.

Diabase, fine- to medium-grained, dark gray to black intrusive igneous rock. It is extremely hard and tough and is commonly quarried for crushed stone, under the name of trap. Although not popular, it makes an excellent monumental stone and is one of the dark-coloured rocks commercially known as
Basalt is a fine-grained, dark-colored volcanic rock formed by the rapid cooling of lava at or near the Earth's surface. Its texture and structure are determined by several factors, including the rate of cooling, the …

Alkaline basalt is relatively poor in silica and rich in sodium. It is silica-undersaturated and may contain feldspathoids, alkali feldspar and phlogopite. Boninite is a high-magnesium form of basalt or andesite that is erupted generally in back-arc basins, distinguished by its low titanium content and trace element composition. Petrology
Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important …
Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene and iron ore (titaniferous magnetite).Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro.

Although the No. I ore belt appears to be the longest and largest in plan view, it contains only 9.7% of the total Cu reserves because of its relatively lower grade and dispersed orebodies. The No. III ore belt, which holds ca. 73.4% (1.74 Mt Cu @ 0.47%) of the total Cu reserves, is the most productive ore belt.
The Hemrin Basalt (HB) is an abnormal occurrence because of its genesis, mineralogy, textures, rare native metals content, and odd geographic-geologic-tectonic setting. It occurs as a caprock for few NW/SE trending hills in a nearly flat-lying area. The HB is a high-K calc-alkaline, collision-related, continental-arc basalt and consists of …
This study aims to examine the impact of using basalt macro-fibers (BMF) on characteristics of concrete made with recycled concrete aggregates (RCA). Test variables included the initial concrete grade (normal- and high-strength concrete (NSC and HSC)), RCA replacement percentage (30 and 60%), and BMF volume fraction (νf = 0.5 to …

An ore body with a larger extension in length and width, and a smaller thickness is called the ore vein or ore bed. The ore vein can be classified into stratified ore veins and cutting ore veins according to its occurrence relationship with surrounding rocks. The former refers to the ore veins extending consistent with the bedding of stratified ...
Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene.
