“…Reconnaissance mineral exploration based on the distribution of ore metals in stream sediments is a generally accepted method (Hawkes, 1976). Apart from the geochemical signatures around mineralised areas, trace metals also accumulate at very significant levels on and around ancient sites and this patterning persists up to the present day (Bintliff et al, 1992).…”

The extensive territory of the ancient (Hellenistic to Byzantine) city of Sagalassos (SW Turkey) offered a rich variety in natural mineral resources. The frequent occurrence of iron slag in the excavations at the site proved the local working of metal. A geochemical prospection campaign was done in the territory of the ancient city in order to identify or discard the city and its territory as a self-sustaining metallurgical centre. Secondly, the geochemical impact of ancient metallurgy was investigated. Geochemical anomalies identified in stream sediments are explained by the presence of mineralised deposits and ancient metal working. Mg, Cr, Co and Ni anomalies point to chromite and chrysotile-magnetite deposits related to the basic rocks of the Lycian nappes in the area. Fe, V and Ti anomalies indicate the presence of iron mineralisations, which have been worked for iron production in ancient times. Finally, the association of P, Cu, Pb, Mn, As and Ag anomalies are an indicator of human activity at archaeological sites. Within the framework of this geochemical prospection, a metal working site apart from the city of Sagalassos was identified. Here, ore was both extracted and processed to workable iron. D

“…Segundo o modelo de diluição (Hawkes 1976), o teor de um elemento em uma amostra de sedimentos de corrente no exutério de uma microbacia pode ser relacionado ao teor de fundo (background) da microbacia, à área da microbacia e à ocorrência de mineralizações. O modelo adequar-se-ia às situações onde existe um forte controle da dispersão mecânica sobre a variabilidade geoquímica, em função da participação da área de microbacia, que se associa à erosão.…”

“…This results in an average sample density of 1 sample per 2 km 2 . Attempts have been made to quantify the effect of dilution of a dispersion train and thereby provide a sound basis for establishing sample spacing and as an aid in interpretation (Hawkes, 1976). Establishing an optimum sampling density depends on several factors like relief, catchment area and shape of the drainage basin, and obviously also of the aim of the investigation.…”

A stream-sediment survey was carried out for the island of Aruba. Concentrations in stream sediments represent the abundance of chemical elements in the drainage basins. A geochemical atlas was created from the collected data and natural background values were established. Cluster analysis and pattern recognition techniques were used to gain a better understanding of the data set.Two cluster models were selected to study the various geochemical controls on the sediments and to establish a spatial basis of environmental-quality settings for the development of future environmental policies. The first cluster model was suitable to recognise in some detail the reflection of the geology on the geochemistry of the stream sediments. The second, coarser cluster model stressed the importance to distinguish between the two main Iithological units of the island when instituting natural background values. Not one uniform value per element is valid, but the value depends on the lithology.
