5.1 Formation
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Dacite vs Laterite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Dacite and Laterite Reserves. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Dacite vs Laterite information and Dacite vs Laterite characteristics in the upcoming sections.
