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 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 is typically classified as an igneous rock, specifically a volcanic rock, and is not categorized as either foliated or nonfoliated since those terms primarily apply to metamorphic rocks. Foliation refers to the alignment of mineral grains under pressure, which is not relevant to andesite. Instead, andesite has a fine-grained texture and can contain a mix of minerals, but it lacks the layered or banded appearance characteristic of foliated rocks.
Andesite has an intermediate composition between "basic" and "acid."
