Metallographic and mineralogical
results demonstrate
the occurrence of
both oxides (Figure 3a-3b,
previous page) and sulphides
(Figure 4a-4b) in
the samples.
Finally, lead isotope analysis
will be used to characterise
potential ore
sources in northern Chile.
Öur future research plans
include investigation of
the contexts of metal production
in the area. The

Introduction
Out of the total of thirteen
cave sites found on the entire
eastern Adriatic coast
and hinterland from the
Late Glacial period, Vela
Spila on Korc ula, Vlakno on
Dugi otok, Zemunica in Dalmatinska
Zagora and
Kopac ina on Brac , were
discovered in Dalmatia
(Figure 1).
First explorations of the
Kopac ina cave were carried
recovery and characterisation
of production-related
materials such as slag and
other metallurgical byproducts
will enable us to
reconstruct the technological
processes involved in
the extraction of metal
from ore. Geochemical
analysis will allow us to
explore the all-important
relationship between various
local ore sources and
archaeological slags and
furnace sites, and between
the copper produced at the
out in 1891 by F. Bulic and
J. Szombathy. This report
represents a results summary
of the quantitative
analysis of lithic assemblage
discovered during
excavations in the Kopač
ina čave (Figüre 2) led by
B. C ec uk from 1978 to
1993 (C ec uk 1996) and the
integral article is in print
(Vuko-savljević et al. 2011).
The laboratory part of the
petroarchaeological analy-
identified sites and the metal
artefacts from the Atacama
region. Önce the primary
production forms and
contexts have been established,
efforts will be made
to trace any changes in the
technology or choice of raw
materials. Because technology
is entwined with cultural
dynamics, the study will
seek to reconstruct the social
and economic processes
of which this industry
was a part.

them as sulphides.

sis of lithic assemblage was
performed at the Curt-
Engelhorn-Zentrum
Archa ometrie in Mannheim,
which started as part of the
study on raw material procurement
in prehistoric
lithic industries in Middle
Dalmatia (Perhoč 2009a;
Č eč ük 1996).
The purpose of petroarchaeological
analysis is to
indicate the likely origin of
stones used to make Kopa-
