Title

Observing Posidonius

About this image

Posidonius crater on April 25 2023. An hint of the small swell is detectable. Using LROC GLD100 dataset French et al. (2015) identify a domical feature, located near the western rim of Posidonius. If an igneous intrusion occurred near the western rim of Posidonius, as proposed by French et al. (2015), a slightly elevated terrain should be detected as an up-bowing of the soil, which could be visible in terrestrial telescopic images taken under oblique solar illumination. The up-bowing of the soil, detected in the telescopic image, confirms the assumption reported by French et al. (2015) that an igneous intrusion occurred in this region.
