No. Calcium carbonate is found in sedimentary and metamorphic rocks. Igneous rocks such as andesite are composed almost entirely of silicates.
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
Correct. Andesite generally does not have a high enough silica content for quartz to form.
calcium carbonate
The molecule of limestone (calcium carbonate, CaCO3) contain 5 atoms.
Both rhyolite and andesite typically contain the minerals quartz, feldspar (particularly plagioclase and alkali feldspar), and biotite. They may also contain other minerals such as hornblende or pyroxene, though these are more variable. The presence of these minerals contributes to their characteristic compositions and textures. Rhyolite is generally more silica-rich than andesite, resulting in differences in mineral proportions.
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.
No. Andesite is a volcanic rock.
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.
No. Andesite is an extrusive igneous rock.
No. It is volcanic. The plutonic equivalent of andesite is diorite.
Yes. Andesite is an extrusive igneous rock.
Yes. Andesite is the extrusive equivalent of diorite
