CommentsEquivalent to: P&W AM 44 of the National Roman Fabric Reference Collection (Tomber & Dore, 1998: 108) |
Visual characteristicsA hard, sandy fabric often with inclusions of limestone, serpentine, and sometimes displaying some dark grains of pyroxene. Ranging in colour from pinkish-cream (7.5YR 8/2-4) to reddish-yellow (5YR 7/6). |
PetrologyThin-sectioning shows there are a variety of fabrics. The major inclusions are often pieces of limestone with a scatter of pyroxene, serpentine and volcanic material. This indicates a source area composed of ultra-basic as well as sedimentary rocks. Heavy mineral separation has produced an assemblage dominated by grains of pyroxene, mostly diopside and enstatite (Williams, 1979). The presence together of diopside and enstatite, and the comparative lack of other minerals, especially zircon, suggests derivation from peridotite (Peacock & Williams, 1986: Class 44). |
