Andesite is an extrusive igneous rock.
Andesite rock typically has a hardness of around 7 on the Mohs scale, which means it is relatively hard and durable. It is commonly used in construction and landscaping due to its strength and resistance to wear and erosion.
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
Three minerals commonly found with quartz in andesite rock are feldspar (specifically plagioclase), biotite mica, and amphibole (such as hornblende). These minerals are all typically present in andesite as part of the overall composition of the rock.
Dacite is an extrusive rock that has a composition similar to andesite. Both rocks are rich in silica and belong to the intermediate composition category. They form from the volcanic eruption of magma that is intermediate in composition between felsic and mafic.
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.
