“…and the University of Pennsylvania Museum to investigate, initially, the promising metallurgical evidence at two hills locally named 'Phu Lon', or 'Bald Mountain', situated on the southern banks of the Mekong (102.140 E,18.204 N, see Pryce and Abrams, 2010). In 1985, TAP excavations at Phu Lon resulted in the discovery of Southeast Asia's first prehistoric primary metal production site, with finds of extant mining galleries, hammerstones, anvils, crushed malachite and skarn host rock, ceramic moulds, and small spouted ceramic crucibles of the 'common' Southeast Asian type (see White and Hamilton, 2009: 365e367) evidencing copper ore mining, beneficiation, and copper-base founding activities .…”

“…Natapintu, 1991). The Valley complex contains three copper mineralisations at Khao Tab Kwai, Khao Phu Kha, and Khao Pa Daeng (the latter two present evidence of pre-modern, though undated mining, and recent mining has obliterated any sign of ancient galleries at the former), and two major smelting sites at Non Pa Wai (c. 5 ha,100.678 E,14.971 N) and Nil Kham Haeng (c. 3 ha,100.656 E,14.957 N) (Pigott et al, 1997;Pryce and Abrams, 2010). The many tonnes of slag, technical ceramic, and mineral unearthed during three seasons of excavation at Non Pa Wai and Nil Kham Haeng evidenced industrial scale copper production activity dated to at least the Early (c. 500 to c. 300 BCE) and Mid/Late (c. 300 BCE to c. 500 CE) Iron Age, respectively.…”

“…Researchers previously achieved mixed success using satellite imagery to map archaeological slag. Pryce and Abrams published efforts to extract spectral signatures of ancient copper mining sites in Thailand from ASTER imagery [1]. Band combinations across multispectral wavelengths (VNIR-SWIR) were examined and spectral indices were used in attempts to distinguish unique spectral features indicative of archaeological targets.…”

Detecting and Mapping Slag Heaps at Ancient Copper Production Sites in Oman

This study presents a new approach for detection and mapping of ancient slag heaps using 16-band multispectral satellite imagery. Understanding the distribution of slag (a byproduct of metal production) is of great importance for understanding how metallurgy shaped long-term economic and political change across the ancient Near East. This study presents results of slag mapping in Oman using WorldView-3 (WV3) satellite imagery. A semi-automated target detection routine using a mixed tuned matched filtering (MTMF) algorithm with scene-derived spectral signatures was applied to 16-band WV3 imagery. Associated field mapping at two copper production sites indicates that WorldView-3 satellite data can differentiate slag and background materials with a relatively high (>90%) overall accuracy. Although this method shows promise for future initiatives to discover and map slag deposits, difficulties in dark object spectral differentiation and underestimation of total slag coverage substantially limit its use. Resulting lower estimations of combined user’s (61%) and producer’s (45%) accuracies contextualize these limitations for slag specific classification. Accordingly, we describe potential approaches to address these challenges in future studies. As sites of ancient metallurgy in Oman are often located in areas of modern exploration and mining, detection and mapping of ancient slag heaps via satellite imagery can be helpful for discovery and monitoring of vulnerable cultural heritage sites.

This article presents the results of recent research on the historical period of west-central Thailand between the eleventh and thirteenth centuries. At this time Dvaravati was in a stage of decline while the prominent rivals of Pagan and Angkor began to prosper. The construction of stone sanctuaries in the Bayon style in west-central Thailand has caused serious debate regarding the influence of Jayavarman VII over that part of Thailand. However, the main point of the present study is that the successors of Dvaravati can be considered to have played a significant part in the socio-economy of that period. This research explores the landscape of the study region using remote sensing techniques as well as carrying out conventional methods of fieldwork. New discoveries and current evidence are discussed, along with some issues concerning the archaeology of the post-Dvaravati, pre-Sukhothai transitional period (c . a.d. 1100–1300). West-central Thailand is believed to have been an economically desirable land with rich resources throughout its history. It is hoped that this work will contribute to the understanding of the social changes after the Dvaravati period when the economic power shifted to other parts of Mainland Southeast Asia.
