Igneous Rocks
Igneous rock is shaped via the cooling and solidification of magma or lava. The magma may be derived from partial melts of existing rocks in both a planet’s mantle or crust.
Pyroxenite
Pyroxenite is an ultramafic igneous rock that contain pyroxene group minerals such as augite, diopside, hypersthene, bronzite or enstatite. This is a coarse-grained rock...
Ignimbrite
Ignimbrite is an expansion of hardened tuff. Ignimbrites are igneous rocks made up by crystal and rock fragments in a glass-shard groundmass, albeit the original texture of the groundmass is probably obliterated due to high degrees of welding. The term ignimbrite isn't always encouraged by means of the IUGS Subcommission on the Systematics of Igneous Rocks.
Diabase or Dolerite
Diabase, also known as dolerite, is a type of igneous rock that holds significance in the field of geology due to its unique characteristics...
Lamprophyre
Lamprophyre is ultrapotassic igneous rock that is occurring as dikes, lopoliths, loccoliths, stocks and small intrussion. It is alkaline silica-undersaturated mafic or ultramafic rocks...

Lapilli, which means "little stones" in Italian, refers to small rock fragments ejected during volcanic eruptions. These fragments typically range in size from 2...
Tinguaite
Tinguaite is a type of volcanic rock, primarily composed of nepheline and alkali feldspar, with lesser amounts of other minerals such as amphibole, biotite,...
Phonolite
Phonolite is a type of volcanic rock that belongs to the family of igneous rocks. It is characterized by its unique mineral composition and...
Pillow Lava
Pillow lava is a type of basaltic lava that forms underwater, typically in the ocean. It gets its name from the characteristic pillow-like shapes...
Indigo Gabbro (Mystic Merlinite)
