WebTypical felsic rocks are granite and rhyolite (Figure 3.13). The cooling behaviour of intermediate magmas lie somewhere between those of mafic and felsic magmas. Typical intermediate rocks are diorite and andesite … WebGranite. Granite is an intrusive igneous rock composed primarily of feldspar, quartz, and smaller amounts of mica. It has a phaneritic texture, meaning that individual crystals can be seen with the naked eye. Because of its relatively high quartz and feldspar content, granite tends to be light in color (felsic). WebMagnetic susceptibility measurements performed on rock outcrops and hand samples from the study area also reveal lower magnetic susceptibilities for sedimentary and felsic intrusive rocks, moderate susceptibility values for metamorphic, felsic extrusive, and intermediate igneous rocks, and higher susceptibility values for mafic igneous rocks. headphone namemc

WebMay 6, 2024 · Felsic igneous rocks, as a whole rock, tend to have light colors or shades: white, pink, light brown, light gray. Mafic igneous rocks, on the whole, tend to be dark colored, commonly black or dark gray. Most mafic magma originates by melting of rocks in the mantle that are extremely rich in iron and magnesium. Felsic magma usually … WebFelsic: Rich in silica (> 65%), poor in iron and magnesium.(E.g. granite, right.) Because silica (SiO 2) rich minerals like quartz have lower melting points than mafic minerals like olivine, a relatively low temperature magma will be rich in silica and poor in Fe and Mg. Conversely, a felsic magma can remain liquid at lower temperatures. Note: On Earth, …
