How can you use andesite?
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.
What is andesite?
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.
Is andesite foliated or nonfoliated?
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.
What is the color of a Andesite rock?
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
What is the difference in composition between a dacite and an andesite?
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.
What is the streak color of andesite?

Is andesite sandstone?

Is andesite a mineral?

How old is andesite?

Is Andesite an igneous?

Is andesite an extrusive rock?

Is andesite a foliated rock?

What are andesite rocks?
Andesite rocks are Igneous rocks. They are jagged and rough, and come from cooled magma.
How do you determine whether a rock is a rhyolite or an andesite?
The composition of the rock will determine whether it is a rhyolite or an andesite.
Is andesite intusive?
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.
Where does andesite form?
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
