The amphorae of groups I to IV are made from calcareous
(marly) clays. This could be ascertained by thin sections only for
two samples and should be proved for the others, too. The first
two groups are characterized by very high Cr and high Ni trace
contents and thus are dearly distinct from the other groups.
Because of the similarity in the major element concentrations, the
six samples of group I, in spite of their large variation in Cr and Zr,
were combined in one. In thin sections samples D713 and D714
are nearly identical in the calcareous matrix and in grain-size,
quantities and types of non-plastic inclusions, mainly of chert
including some radiolarite, and quartz (Tabs. 2 and 3). Bioclasts
typical of the Upper Miocene (Tortonien) can be detected in one
sample. In the other sample, a high firing temperature is the reason
why only pores can be related to these bioclasts. Sample D677
(group II) may be distinguished from the first group by higher
nickel trace contents. Two other samples (D619, D672),
provisional groups III and IV, are different from all previously
discussed samples in significantly lower chromium and nickel trace
contents. The differences between these two samples, however, are
so small that new samples and additional thin section studies may
change these groups to only one group.
Samples D711 and D712 are chemically (Tab. 1) and in thin
sections (Tabs. 2 and 3) very similar and characterize amphorae
made from a micaceous, non-calcareous and very iron-rich clay
with low Cr and Ni contents. Beside the exceptionally high iron
content, these samples are also characterized by high aluminium
and high potassium contents. Grain size distributions are similar in
both samples. The mostly unrounded non-plastics up to 0.5 mm
consist of polycrystalline quartz; some with recrystallized rims as
are typical of a sedimentary origin. Besides, magmatic and
metamorphic rock fragments, some with epidote, are found.
The remaining three analyzed samples, also with high
aluminium, iron, potassium and low chromium and nickel, do not
form a homogeneous group. This is due to largely varying calcium
136
(marly) clays. This could be ascertained by thin sections only for
two samples and should be proved for the others, too. The first
