Basalt Granite Rock

Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.

Basalt granite rock.

Both are igneous rocks which means that they cooled from a magma the earth gets very hot just below the surface and there is lots of liquid rock available. Its principle minerals include pyroxene feldspar and olivine. It most commonly forms as an extrusive rock such as a lava flow but can also form in small intrusive bodies such as an igneous dike or a thin sill it has a composition similar to gabbro the difference between basalt and gabbro is that basalt is a fine grained rock while. Basalt is an extrusive or intrusive rock that makes up most of the world s oceanic crust.

On the other hand granite occurs above the ocean and makes up much of continental crust. One other difference between basalt and granite pertains to the way these two types of rocks split when putting under pressure. It is common both on earth and other planetary bodies. ˈ b æ s ɔː l t ˈ b æ s əl t is a mafic extrusive igneous rock formed from the rapid cooling of lava rich in magnesium and iron exposed at or very near the surface of a terrestrial planet or a moon.

It can form volcanic islands when it is erupted by volcanoes in ocean basins. Andesite basalt dacite obsidian pumice rhyolite scoria and tuff.

Vesicular and amygdaloidal textures. More than 90 of all volcanic rock on earth is basalt and the eruption of basalt lava is observed by geologists at about 20. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Concrete building materials contracting construction services.

Basalt and granite actually have quite a bit in common. Examples of intrusive igneous rocks are. It forms from lava flows which extrude onto the surface and cool. The rock has also built huge plateaus on land.

Basalt is an extrusive igneous rock whereas granite is an intrusive ingenuous rock. Granite is the ultimate silicate rock. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Basalt is fine grained so the individual minerals are not visible but they include pyroxene plagioclase feldspar and olivine these minerals are visible in the coarse grained plutonic version of basalt called gabbro.

Granite is an igneous plutonic rock which is. The dark plains on the moon known as maria and possibly the volcanoes on mars and venus are made of basalt. Some cool so quickly that they form an amorphous glass. Diabase diorite gabbro granite pegmatite and peridotite.
