Basalt: Igneous Rock - Pictures, Definition, Uses
Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive

Volcanic rock - Wikipedia
Basalt is a very common volcanic rock with low silica content. Rhyolite is a volcanic rock with high silica content. Rhyolite has silica content similar to that of granite while basalt is compositionally equal to gabbro. Intermediate volcanic rocks include andesite, dacite, trachyte, and latite. [citation needed]

2022年3月3日 Basalt is made of molten rock, similar to granite and gabbro. Basalt is a sedimentary rock, which means it is formed from sediments. In this case, basalt can be made of sediment that melts when a volcano erupts. Sedimentary rocks are not derived from molten rocks. Basalt is a common extrusive rock found on Mars, Earth, and Venus.

2023年1月9日 It can turn the surface into molten lava with a melting temperature ranging from 1500 to 1700 °C [15,16]. The condition of basalt is significantly influenced by the temperature of the quenching process, which results in highly complete crystallization. As the two significant minerals, plagiocene and pyroxene account for over 80% of basalts.

2022年11月9日 Basalt (/bəˈsɔːlt, ˈbæsɒlt, -sɔːlt/) is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content, resulting in rapid lava
