- Abstract
- Geochemical investigations on samples of
pumice and lava extracted from the mortars
and concretes of the Forum of Caesar and
the Forum and Markets of Trajan are presented
and integrated with previous analyses
of lava samples from Rome and Pompeii,
and of pumices from the Colosseum and the
Dioclethian's Bath, with the aim to identify
the lithological provenance of these materials.
Discrimination diagrams based on ratios
of selected trace elements (i.e., Zr/Y, Nb/Y,
Th/Ta, Nb/Zr) allow us to recognize the geochemical
signature of the different volcanic
regions of central Italy. These diagrams indicate
that in the mortars of the Forum of
Caesar and Forum of Trajan, the Roman
builders integrated the scanty pumices from
deposits of the Monti Sabatini Volcanic District
near Rome with others coming from
the Vesuvius and Phlegrean Fields. Some of
the pumices employed in the vaulted ceilings
of these monuments display a peculiar
geochemistry that has a unique correspondence
with a pyroclastic deposit recovered
in a borehole drilled on the southern fl anks
of Vesuvius. Similarly, lava fl ows from this
borehole display a different trace-element
signature with respect to that of other coeval
lava fl ows of the northern fl anks of Vesuvius,
and it has a closer correspondence to that
of the archaeological lava samples. These
observations, integrated with historical and
archaeological data, indicate that the Roman
builders had a profound empirical knowledge
of the physical properties of the volcanic
rocks from different regions, and suggest that
a systematic cultivation of lightweight volcanic
material occurred in the area of Pompeii
for exportation to Rome and, likely, to other
regions of the Mediterranean. (literal)
