Andesite rocks are Igneous rocks. They are jagged and rough, and come from cooled magma.
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
No. Calcium carbonate is found in sedimentary and metamorphic rocks. Igneous rocks such as andesite are composed almost entirely of silicates.
andesite
Andesite is not any age in particular. Some deposites of andesite may be hundreds of millions of years old. However, since andesite is volcanic, some andesite rocks may only be minutes old.
Porphyritic Rocks are rocks that have big and small crystal's like the Igneous Rock "Andesite".
Volcanic rocks are extrusive igneous rocks.
Andesite is a nonfoliated rock, meaning it does not have a layered or banded appearance like foliated rocks such as slate or schist. Andesite forms from volcanic activity and solidifies without undergoing the intense pressure and heat required for foliation to occur.
Igneous rocks that cool above ground are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the Earth's surface and cools rapidly.
Andesite has an intermediate composition between "basic" and "acid."
