Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
