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...

Lithophysa (Volcanology 🌋)

A lithophysa is a felsic volcanic rock with a spherulitic structure and interior cavity with concentric chambers. Its outer shape is spherical or lenticular. They vary in size from very small up to twelve feet in diameter depending on the age of the magma chamber. These rocks are usually found within obsidian or rhyolite lava flows. Lavas low in feldspar...

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...

Every photo must be perfect to post on social media.
This photo is not perfect.
It is not perfect because it is two photos.
Two photographs are needed to tell the story.
The story of the giraffe sized hole in the wonderful extruded and twisted volcanic rock.
Oh well, not everything can be perfect.
(he says, cringing because this photo is not perfect, and this explanation is not perfect).

Piperno (Geology ⛰️)

Piperno is a magmatic rock present in areas where there has been volcanic activity. Piperno abounds in Campania; the areas from which it was obtained were the city of Quarto, Soccavo, Pianura and Nocera Inferiore in the supervolcano region of the Phlegraean Fields. The Piperno layer, with the overlying Breccia Museo, is clearly visible at the base of the Camaldoli hill, in the Soccavo and Verdolino ...

Volcanic block (Volcanology 🌋)

A volcanic block is a fragment of rock that measures more than 64 mm in diameter and is erupted in a solid condition. Blocks are formed from material from previous eruptions or from country rock and are therefore mostly accessory or accidental in origin. Blocks also occur due to the impact and breakage of volcanic bombs. Bombs can also occur due to the disruption of the cr...
