Irnini Mons [SEP] located on astronomical body
Irnini Mons
Irnini Mons is a volcanic structure on the planet Venus, and is named after the Assyro-Babylonian goddess of cedar-tree mountains. It has a diameter of , a height of , and is located in Venus' northern hemisphere. More specifically, it is located in the central Eistla Regio region at () in the V-20 quadrangle. Sappho Patera, a diameter wide, caldera-like, depression tops the summit of Irnini Mons. The primary structural features surrounding Irnini Mons are graben, seen as linear
from a primarily shield volcano structure to a primarily corona structure due to continued lithosphere thinning and lack of resurfacing flows. Another hypothesis is Irnini Mons was originally a corona which was uplifted due to compressive forces.
Geology of Irnini Mons Regional Geology.
The low viscosity basaltic flows that compose Irnini Mons overlay several regional plains and tessera units of Eistla Regio. The oldest observed rocks are a highly deformed tessera unit with ridges and grabens at high angles between one another which create the tessera-textured pattern for which it is named.
