(Northern) Campanian amphorae 2 (CAM AM 2)

Three samples

General appearance

Typically this fabric is orange-brown (5Y 6/6) or red-brown (10R 5/6), occasionally with buff (7.5YR 8/3) surfaces. It is very hard with a hackly fracture and rough surface. Peacock & Williams Class 10 (Dressel 2–4) and derivative (see above) amphorae were produced in this fabric.

Hand specimen

A calcareous matrix, sometimes slightly silty, with large ill-sorted volcanic rock inclusions characterises this fabric. A wide range of variability can be seen between samples, particularly in the relative proportion of inclusions, but it is distinguished from the better sorted, more granular CAM AM 1 by being dominated by rock fragments rather than accessory minerals. Dark and red-brown rocks are abundant, followed by common feldspar, and sparse accessory minerals, quartz, volcanic glass and occasionally fine gold mica. These inclusions measure between 0.2–3.0mm, although not normally exceeding 0.2mm, with no single type falling into a particular size range. Microfossils can be seen in some samples.

Thin section

This is a calcareous clay containing common ill-sorted subangular silt to coarse-sand grains, typically 0.5mm–3.0mm, including (frequently altered) altered lava and volcanic glass, clinopyroxene, microcrystalline calcite, sanidine and quartz. Plagioclase is less common, and sandstone occurs rarely. Rare threads of mica are present but not considered diagnostic.

Source

The petrology of this fabric suggests a source in northern Campania, in the region of the Bay of Naples (Arthur & Williams 1992).
