Volcanic activity in rift valleys is important in several different ways to both geology and. archaeology. First, the rocks, such as rhyolite and basalt, and also ashes are important for. correlation and dating the deposits and archaeological sites in rift valleys.olcanic activity in rift valleys is important in several different ways to both geology and. archaeology.

Rift volcanoes occur where tectonic plates diverge, often on the ocean floor. These are generally less explosive. Hot spot volcanoes occur in the middle of plate boundaries where magma exits from weaknesses in the earth's surface. The Hawaiian Islands are an example of hot spot volcanoes. The most active area of volcanic activity occurs along the pacific plate boundary which is often referred to as the 'Pacific ring of fire'.
