“…Most detection limits are between 0.01 and 0.02 elemental wt%. Spinel analyses were plotted on the modified Johnston prism using the Spinel Web software of Antonini et al (2020). The modal mineralogy of each fragment was determined by point-counting 750-1,200 points on backscattered electron images of the fragments, after identification of the phases by X-ray mapping and EDS and WDS techniques.…”

Multiple Shallow Crustal Origins for Spinel‐Bearing Lithologies on the Moon: A Perspective From the Luna 20 Mission

Spinel (predominantly the MgAl 2 O 4 -end member)-bearing crustal lithologies have long been recognized in the Apollo sample collection. However, such lithologies are rather rare and individual samples are small in mass (<1 g). It has been inferred since the early 1970s that these lithologies (e.g., extensively shocked spinel ± cordierite troctolite clasts) were excavated during basin-forming events from the deep lunar crust and/or upper mantle

“…These analyses were evaluated for quality using oxide totals and appropriate stoichiometric criteria (e.g., site occupancy, cation totals) based on the crystal chemical rational drawn from several prior works (e.g., Cameron & Papike, 1981;Karner et al, 2006;Papike et al, 1976Papike et al, , 2009.

Where Is the Lunar Mantle and Deep Crust at Crisium? A Perspective From the Luna 20 Samples

et al. 2023

Remote sensing observations have been interpreted to indicate that the Crisium basin‐forming event excavated deep crust and upper mantle. Samples from the highlands adjacent to the Crisium basin returned by Luna 20 (L‐20) bring a unique perspective for evaluating this concept. The magmatic lithologies returned from the noritic Hilly and Furrowed Terrain (nHFT) by L‐20 are coarse‐grained feldspar (>300 μm) with inclusions of pyroxene, and finer‐grained norites, troctolites, spinel troctolites, and gabbros (<100 μm). These two suites represent ferroan anorthosites (FANs) and the Mg‐suite, respectively. There is limited evidence for mantle or deep crustal material within the nHFT samples. Ultramafic rocks such as dunites and orthopyroxenites are absent, and Mg‐rich olivine‐ and orthopyroxene‐bearing‐assemblages are derived from magmatic rocks emplaced in the shallow crust. These lithic fragments represent pre‐Crisium episodes of magmatism (Mg‐suite) and lunar magma ocean products (FANs). The lack of deep lithologies at the L‐20 site seems contradictory to excavation models for Crisium. Mineralogical‐chemical differences suggest a higher FAN component in the rim and that this represents FANs excavated from the deep lunar crust. If it exists, the Mg‐rich olivine previously identified within the Crisium rim is most likely related to deep, complementary versions of the Mg‐suite rocks from L‐20. The material associated with the Crisium basin is not derived from the lunar mantle but represents crustal lithologies from the shallow to deep crust, a substantial mantle component may have been incorporated into the Crisium basin impact melt sheet, or that our “Earth‐analog” for the lunar upper mantle is incorrect.
