“…They had also mentioned that AMAs of these domes do not show a clear spatial correlation of ages vs. location of dated domes. Thus, derived ages in this study are also consistent with that of earlier studies (Arya et al 2014;Gebhart et al 2016;Hiesinger et al 2016).…”

“…This implies that domes in this region might be formed at about 2.98 Ga and adjoining basalts might be embayed during latter phases around 1.98 Ga ago. An age of basaltic unit is also consistent with the age of basalts located at SW edge of Marius Hills region (Arya et al 2014). Recent studies by Gebhart et al (2016) also show that Absolute Model Ages (AMA) of low shields varies between 1.03 and 3.65 Ga and AMAs of adjacent mare basalts vary between 1.2 and 3.69 Ga.…”

“…They also estimated rheological parameters of three domes based on the assumption of two-phase eruption. Later to this study, rheological parameters of a dome located to the south of Rima Galilaei in the Marius Hills region were estimated by Arya et al (2014).…”

“…In this section, rheological parameters such as viscosity and effusion rate are estimated based on morphometric properties of the domes/cones determined in the previous section 4.2. Approach for estimation of rheological parameters of the domes in the study is adopted from earlier studies (Wilson and Head 2003;Wöhler et al 2006Wöhler et al , 2007Lena et al 2007Lena et al , 2009Lena et al , 2013Arya et al 2014). This model estimates several parameters like yield strength τ , the pressure or stress that must be exceeded for the lava to flow (Wolff and Sumner 2000), the plastic viscosity η, a measure for the fluidity of the erupted lava, the effusion rate E, the lava volume erupted per second, and the duration of the effusion process.…”

Morphometric and rheological study of lunar domes of Marius Hills volcanic complex region using Chandrayaan-1 and recent datasets

Marius Hills volcanic complex is one of the most important regions on the lunar surface having an abundant number of volcanic features like domes and cones. Systematic mapping of 106 domes/cones in the Marius Hills region was carried out in this study using high-resolution orthoimage and digital elevation models of Chandrayaan-1 and Kaguya missions. Various morphometric parameters like diameter, height, volume, flank slope, circularity index and form factor are derived for all the mapped domes. The rheological parameters, such as viscosity and eruption rate are estimated for isolated domes and cones superimposed over low domes. The morphometric and rheological properties of these domes are comparable to those located in the area near to Hortensius crater and other mare regions. Surface ages derived for a selected region in NW portion of the Marius Hills volcanic complex using crater sizefrequency distribution technique yields ages of 2.98 and 1.91 Ga. It suggests that the domes in this region formed at about 2.98 Ga ago, and then, the younger mare basalts likely embayed this region about 1.98 Ga ago. Stratigraphic sequence of rilles, wrinkle ridge and domes shows that wrinkle ridges are the oldest, while the rilles are younger than the domes.

“…By analyzing the composition of rocks, we can determine the silica content, titanium, and iron abundances, which are directly related to the magma viscosity. These, together with the physical properties of the rock (e.g., density and porosity), will provide basic information for rheologic modeling in the analysis of formation mechanism of steep‐sided domes on the Rümker plateau and provide references for the study of other volcanic domes on the Moon [ Lena et al ., , ; Wöhler et al ., ; Arya et al ., ]. In addition, as the formation of steep‐sided domes may represent the last stage of Mons Rümker volcanism, dating of the rocks will help us better constrain the duration of volcanism in the Mons Rümker region and improve the CSFD dating method.…”

Mons Rümker is a large volcanic complex in Oceanus Procellarum on the Moon and is a candidate landing site for China's Chang'E‐5 sample return mission. We conducted a comprehensive study of the topography, geomorphology, composition, and stratigraphy of the Mons Rümker region with multisource remote sensing data in order to better understand the geology of the region and provide further support for the Chang'E‐5 mission. The results show that the Rümker plateau stands 200–1300 m above the surrounding mare surface and 75% of the plateau has a slope of less than 3° at a baseline length of 30 m. Domes are the most prominent volcanic landforms in Mons Rümker and a total of 22 domes were identified and divided into two types that may represent different stages of volcanic activity. Spectral analyses indicated that Mons Rümker is covered by low‐Ti basalt and the dominant mafic mineral is high‐calcium pyroxene, though signs of mixing of highland materials and basalt have been found. Mons Rümker has three main basalt units, and their absolute model ages are 3.71 Ga, 3.58 Ga, and 3.51 Ga, respectively. Steep‐sided domes could be the youngest volcanic features on the plateau with indications that they were active until the Eratosthenian. A new geologic map of the study region was produced and used to interpret and discuss the geologic evolution of the region. Finally, we propose two candidate landing sites for the Chang'E‐5 mission.
