Andesite does not have pH. pH is a measure of how acidic or basic an aqueous solution is, meaning a solution in which the solvent is water. Andesite is a rock, not an aqueous solution. The terms "acidic" and "basic" were once used by scientists to describe the composition of igneous rocks, but this was based on an incorrect interpretation of their chemistry. These terms were replaced with felsic and mafic respectively. In either case, andesite is considered intermediate.
Andesite is an igneous rock that can be used in the construction field. Andesite is used mainly for making tiles, bricks, or stones that are suitable for water or landscape gardens. They use andesite to make tiles because they are naturally slip resistant.
Andesite is a type of igneous rock that is typically light to dark gray in color. It forms when magma from the Earth's mantle solidifies and cools relatively quickly. Andesite is commonly found in volcanic regions such as the Andes Mountains in South America.
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.
The dominant color of the andesite is black with some spots of red and gray. from: http://192.211.16.13/curricular/MN/tieton_andesite.htm
The main difference between dacite and andesite lies in their silica content. Dacite has a higher silica content than andesite, making it more viscous. Dacite also typically contains more quartz and less mafic minerals than andesite.
No. Andesite is a volcanic rock.
No. Andesite is an extrusive igneous 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. 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
No. Foliation is a term that applies to metamorphic rocks. Andesite is igneous.
Andesite rocks are Igneous rocks. They are jagged and rough, and come from cooled magma.
The composition of the rock will determine whether it is a rhyolite or an andesite.
Andesite is a type of igneous rock that can form both intrusively (inside the Earth's crust) and extrusively (on the Earth's surface). When andesite forms intrusively, it typically cools slowly and can create large crystals.
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .
