Ben Ghida Abstract: Slate rock has been analyzed for more than 170 years This large tumulus consists of two juxtaposed cairns (heap and was among the first geological features to be used in a number of stones) with an immense mass of different types of granite of countries such as Spain, France, Wales, North America and dry-stones (Giot et al., 1995) carefully stacked together, Brazil. Early observations recognized the importance of slate into the construction of roofs, cladding, pavements, or roads. covering eleven funerary chambers with corridors.

ROMAN LEAD SILVER SMELTING at RIO TINTO the Case Study of Corta
ROMAN LEAD SILVER SMELTING AT RIO TINTO The case study of Corta Lago Thesis submitted by Lorna Anguilano For PhD in Archaeology University College London I, Lorna Anguilano confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. ii To my parents Ai miei genitori iii Abstract The Rio Tinto area is famous for the presence there of a rich concentration of several metals, in particular copper, silver and manganese, which were exploited from the Bronze Age up to few decades ago. The modern mining industry has been responsible for both bringing to light and destroying signs of past exploitation of the mines and metal production there. The Corta Lago site owes its discovery to the open cast exploitation that reduced the whole mount of Cerro Colorado to an artificial canyon. This exploitation left behind sections of antique metallurgical debris as well as revealing the old underground workings. The Corta Lago site dates from the Bronze Age up to the 2nd century AD, consisting mainly of silver and copper production slag, but also including litharge cakes, tuyéres and pottery. The project focused on the study of silver production slag from different periods using petrograhical and chemical techniques, such as Optical Microscopy, X-Ray Diffraction, X-Ray Fluorescence, Scanning Electron Microscopy associated to Energy Dispersive Spectrometry and Multi-Collector Inductively Coupled Plasma Mass Spectrometry. The aim of the project was to reconstruct the metallurgical processes of the different periods, detecting any differences and similarities. -
