The Cotopaxi volcano in Ecuador is primarily composed of andesite and dacite rock types. Andesite is a volcanic rock with an intermediate composition between basalt and rhyolite, while dacite has a similar composition to andesite but with more silica content.
Magma can solidify and cool to form igneous rocks such as granite, basalt, or andesite, depending on the composition and cooling rate of the magma.
Rocks with an aphanitic texture have fine-grained crystals that are too small to be seen by the naked eye. Common igneous rocks with this texture include basalt, andesite, and rhyolite. These rocks cool quickly at the Earth's surface, preventing larger crystals from forming.
Igneous rocks formed from hardened lava include basalt, andesite, and rhyolite. Basalt is a fine-grained, dark-colored rock commonly found in oceanic crust, while andesite and rhyolite are intermediate to felsic in composition and typically found in volcanic arcs or continental volcanic regions.
The volcanic equivalent of norite is andesite. Both rock types are classified as intermediate in composition, with norite being a plutonic igneous rock and andesite being its volcanic counterpart formed from the same magma source.
The abundance of andesite and basalt in Leyte is due to its location along the Pacific Ring of Fire, a region known for volcanic activity. The presence of nearby volcanoes and tectonic plate movements has led to the formation of these volcanic rocks in Leyte. Additionally, the continued activity of these geological processes over time has contributed to the abundance of andesite and basalt in the region.

Extrusive rock of an igneous origin, formed from the cooling and solidification of lava. Typical examples include basalt, andesite and rhyolite.

Basalt can be found under the earth. I would like to see real basalt in my lifetime.
Basalt and igneous rocks were formed by what we would call magma/lava
Most lava forms a rock called basalt when it cools.
A pegmatite is a rock formed under certain favorable circumstances that enhance the crystal size of the rock. The crystals would be larger than those in basalt, an extrusive igneous rock, and granite, and intrusive igneous rock.
The volcanic equivalent of norite is andesite. Both rock types are classified as intermediate in composition, with norite being a plutonic igneous rock and andesite being its volcanic counterpart formed from the same magma source.
Around a volcano that has erupted recently, you would find volcanic rocks such as basalt, andesite, and rhyolite. These rocks are formed from cooled lava and ash that are ejected during volcanic eruptions. In some cases, you may also find volcanic glass or obsidian near the eruption site.
