Identification of a lunar volcanic dome termed L1 in Promontorium Laplace and mineralogy

In recent years, with the advancements in digital sensors technology and access to space probes data, more and more lunar features are discovered using ground-based images. Mostly, these features are lunar domes, with tens of such structures being discovered using medium-sized telescopes.

In the following study we examine a lunar dome, termed Laplace 1 (L1), identified using telescopic images, Lunar Reconnaissance Orbiter (LRO) Wide Area Camera (WAC) images, the Laser Altimeter Digital Elevation Model (LOLA DEM), and the LRO WAC-based GLD100 Digital Terrain Model (DTM) along with data from the Chandrayaan-1 Moon Mineralogy Mapper, Diviner dataset and Kaguya Multiband Imager. The dome lies at coordinates of 48.57°N and 26.37°W, at about 36 km south east of the crater Maupertuis, and has a base diameter of 7.6 km ± 0.3 km, a maximum height of 230 ± 20 m, resulting in a slope angle of 3.4° ± 0.3°. We also infer the mineralogical composition of the dome.
