Mafic lava is low in silica and high in iron and magnesium, which makes it less viscous and more fluid compared to felsic lava. It tends to flow easily and often forms basaltic rocks when it cools. Mafic lava eruptions typically result in gentle, effusive lava flows rather than explosive eruptions.

Are mafic rocks solely intrusive or extrusive?
Mafic rocks can be either intrusive (plutonic) or extrusive (volcanic). Intrusive mafic rocks, such as gabbro, form below the Earth's surface through the slow cooling of magma. Extrusive mafic rocks, like basalt, are formed on the Earth's surface through rapid cooling of lava.
Does mauna loa have mafic or felsic magma?
Mauna Loa volcano in Hawaii typically has mafic magma, which is rich in magnesium and iron, resulting in low viscosity and flowing lava. This magma composition contributes to the shield volcano shape and frequent eruptions on Mauna Loa.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is rich in iron and magnesium, which are characteristic components of mafic rocks like basalt and gabbro.
What is the mafic rock that is full of holes and made of dense materials is?
The mafic rock that is full of holes and made of dense materials is basalt. Basalt is formed from lava that has rapid cooling, which traps gas bubbles inside the rock.
Is basalt metamorphic?
No, basalt is an igneous rock formed from the solidification of molten lava. It is not a metamorphic rock.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.
Is mafic or felsic lava produced in mt fuji?
mafic lava is the KIND of lava produced in mount (mt) Fuji.
What is it like in mafic lava?
Mafic lava is more fluid and less viscous compared to felsic lava, which results in faster flows and smoother surfaces. It has a higher temperature and lower silica content, leading to less explosive eruptions and the formation of dark-colored rocks like basalt. Mafic lava typically originates from oceanic volcanoes and can cover large areas with thin, extensive lava flows.
How fast does dacite lava flow compared to mafic lava?
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
Does mafic lava trap gasses?
glass is not an option in mafic
Does paricutin mafic or felsic lava?
Paricutin volcano in Mexico predominantly erupted mafic lava, which is rich in magnesium and iron and has a low silica content. This type of lava tends to flow more easily compared to felsic lava.
What mafic is like?
Mafic is a silicate mineral or rock that is rich in magnesium and iron, and is usually dark in color. It is formed from cooling volcanic lava.
What is silica called?
Mafic lava
Is mauna kea mafic or felsic?
As a shield volcano, Mauna Kea erupts mafic lava.
What lava type does the Santa Ana volcano have?
Mafic
Is mauna loa mafic or felsic?
Mauna Loa is considered a mafic volcano. It erupts basaltic lava, which is characteristic of mafic compositions with low silica content and high magnesium and iron content.
