Refractory (planetary science) (Volcanology 🌋)
In planetary science, any material that has a relatively high equilibrium condensation temperature is called refractory. The opposite of refractory is volatile. The refractory group includes elements and compounds like metals and silicates which make up the bulk of the mass of the terrestrial planets and ast...

Volcaniclastics (Volcanology 🌋)
Volcaniclastics are geologic materials composed of broken fragments of volcanic rock. These encompass all clastic volcanic materials, regardless of what process fragmented the rock, how it was subsequently transported, what environment it was deposited in, or whether nonvolcanic material is mingled with the volcanic clasts. The United State...

Lapilli (Petrology 💎)
Lapilli is a size classification of tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. Lapilli is Latin for "little stones". By definition lapilli range from 2 to 64 mm in diameter. A pyroclastic particle greater than 64 mm in diameter is known as a volcanic bomb when molten, or a volcanic block when solid. Pyroclastic material...

A rock which comes from a deep place of our world and looks green because it is formed of pieces that are also green. This rock is heavy and makes up a large part of the deep rock world.Figure caption excluded from that rule.
