High-titanium mare basalts
WebThe high-titanium basaltic eruptions occurring during the last volcanic activity period can be explained by the three possible scenarios (1) the ilmenite-bearing cumulate rich layer in the core-mantle boundary formed after the mantle overturn, (2) the basaltic material layers beneath the lunar crust formed through upwelling magmas, and (3) … Web1 feb 1979 · The Apollo 17 high-Ti mare basalts are divided into three main compositional groups (Groups A, B and C; Rhodes et al., 1976; Warner et al., 1979; Paces et al., 1991).

WebA comparison of shock compression and release adiabat data to 160 GPa for the 12063 low-titanium mare basalt with previous results for the high-titanium, 70215 mare basalt shows that, while the two rocks have very similar zero-pressure densities, the former is much less compressible above 100 GPa. This demonstrates that rocks with complex mineralogies …
Web23 nov 2024 · High-Ti olivine basalts dated at 2.05 Ga are found to be surrounded by the Late Imbrian (~3.47 Ga) low- to intermediate-Ti basalts in Mare Grimaldi. Low- to intermediate-Ti basalts observed in Mare Riccioli date back to two different volcanic events at ~3.5 Ga and ~3.2 billion years, while patches of basalts having remarkably higher …

Examination of crater densities in several clusters shows that Tycho produced almost 10 6 secondary craters larger than 63 m diameter. This is a lower limit, because … symmetry powerpoint tesUsing terrestrial classification schemes, all mare basalts are classified as tholeiitic, but specific subclassifications have been invented to further describe the population of lunar basalts. Mare basalts are generally grouped into three series based on their major element chemistry: high-Ti basalts, low-Ti basalts, and very-low-Ti (VLT) basalts.
