Abstract

This paper presents the results of a study carried on a collection of 144 metal artefacts from the Early (ca. 2800-2600/2500 a.C.) and the Middle/Final Chalcolithic (ca. 2600/2500-2000 a.C.), found at the site of Leceia (Oeiras, Central Portugal) during the excavations conducted between 1983 and 2000. A systematised analysis of the collection was provided in order to enumerate the different typologies found in the site and to determine their chemical composition. From a typological point of view, a great diversity of artifacts was found, namely, punches, fish-hooks, flat axes, chisels, saws, ingots and foundry remnants. Elemental analysis by X-ray Fluorescence shows that the artefacts were made of copper, wiht a variable occurrence of arsenic, nickel, silver, antimony, bismuth lead, and iron. In this paper, data is exposed and discussed within the regional early metallurgy
