Abstract

Understanding the location and distribution of raw materials used in the production of prehistoric artefacts is a significant part of
archaeological research that aims to understand the interregional interaction patterns in the past. The aim of this study is to explore
the regional locations of the source rock utilized in the production of stone bowls, which were unearthed at the Neolithic (approximately
6500–5500 BC) site of Domuztepe (Kahramanmaraş-Turkey),
via a combination of remote-sensing methods, petrographic and
chemical analyses. To accomplish this task, the stone bowls were
identified mineralogically, geochemically and spectrally, and then
mapped with Advanced Spaceborne Thermal Emission and
Reflection Radiometer (ASTER) sensors. According to the defined
mineralogical composition, which is iron-rich chlorite, the target
areas were selected among geologically potential areas that
would bear similar source rocks in near vicinity and the target
spectral signature was searched within these target areas. In order
to overcome the problem of spectral similarity of chlorite group to
some other minerals such as carbonate or epidote group minerals,
band ratioing (BR) and feature-oriented principal component analysis
(FOPCA) were used with an integrated approach and then their
results were filtered according to the outcomes of the relative
absorption band-depth (RBD) images. The areas with highest potentials
were vectorized and then field checked. Mineralogical investigations
on the collected field samples reveal that there is a
mineralogical match between the source and target material. One
group of stone bowls samples have similar geochemical signatures
as the field samples having ultramafic origins. However, there is
another group of stone bowls samples which are geochemically
dissimilar to the first group of field and bowls samples. The data
regarding the geochemical signatures of these two groups indicate
a genetic relation between the sample sets. Therefore, it is concluded
that the source rock of a major portion of the stone bowls
unearthed at Domuztepe most probably originated from the near
vicinity of the site.
