WebOct 15, 2024 · All norites are classified as cumulates because cumulate textures were identified in all norite thin sections (Fig. 2a), and their bulk-rock Mg#s are significantly higher than the rest of the HLMC (Mg# = 64.6-73.1, with a gap in HLMC from 57.8 to 64.6). WebB2—Cumulate texture: Crystals are equant to slightly elongate, and have a round morphology due to resorption. Olivine phenocrysts are separated by a fine aphyric groundmass (Figure 49.4(C)). Orthocumulate texture comprises phenocrysts wholly suspended in the groundmass. Mesocumulate texture comprises crystals that are just …
