Cuicocha volcano is a beautiful caldera in northern Ecuador 100 km north of Quito. The volcano has a 3 km wide lake filled caldera and sits at the feet of the sharp-peaked (extinct) Cotacachi stratovolcano.
There are gas emissions from several locations in the caldera lake at present indicating the volcano is still active.
Igneous or magmatic rocks: The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.
