Mafic
baslt
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
The color will depend on the mineral composition of the magma.
Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.
Mafic
dark
Dark green to black.
Generally dark with shades of green and black.
baslt
Magma that is low in silica flows readily and produces dark-colored lava. Therefore magma that is low in silica produces Pahoehoe lava. This is called mafic or basaltic magma.
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
The color will depend on the mineral composition of the magma.
Chartreuse is a dark olive-green
Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.
The type of magma which is thick and slow is Felsic Magma.
granitic is light, basaltic is dark.
