Chang'e-6 farside anorthosites indicate hemispherically comparable magma ocean solidification.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ferroan anorthosites (FANs) reflect the nature of the Moon's crust formed during the late-stage lunar magma ocean (LMO). Remote sensing suggests a hemispheric dichotomy in crustal composition, with the farside anorthositic highlands being more magnesian than the nearside. Lacking direct compositional and chronological constraints from farside anorthosites, whether this crustal dichotomy reflects asynchronous LMO solidification or post-LMO crustal reworking remains uncertain. Here we present an integrated petrological, geochemical, and geochronological study of farside anorthosite clasts returned by the Chang'e-6 mission. These clasts exhibit both mineralogical and compositional similarity with nearside Apollo FANs, supporting a comparable LMO-derived primary crust on both hemispheres. A zircon-bearing anorthosite domain contains recrystallised plagioclase enriched in rare earth elements (REE), thorium, and phosphorus, suggesting thermal reworking and metasomatism by a KREEP (potassium, REE, and phosphorus)-rich magma. High-precision lead-lead dating of zircon constrains this reworking event to 4,410 ± 8 Ma, establishing a local lower bound for farside LMO solidification. These findings establish a critical chronological benchmark for farside LMO solidification and offer direct evidence of a comparable primary crust across the Moon, constraining the origin of the crustal dichotomy to post-LMO reworking.
