What are the parent rocks of Basalt and Mica?
dreamlikealice, You may be a little confused about what these materials are. Basalt, pumice, and obsidian are all extrusive igneous rocks, which means that they form from the cooling of lava. That means that their parent material is molten rock, so they don’t really have a “parent rock”. Mica and pyroxene are both names given to groups of minerals (not rocks). They can each form in different types of rocks, so they don’t have any single parent rock – it depends on how they form.
