Abstract
Cheng-hwa Tsang discovered the Nankang site on the Chi-mei Island of Penghu in 1983. According to his preliminary investigation, Tsang had postulated that the Nankang site was probably a prehistoric lithic workshop. Tsang went to the Chi-mei again in May of 2000, with Dr. Barry Rolett of the University of Hawaii and Dr. Yie Shue-wen of Academia Sinica for the purpose of looking for the source materials of the basaltic stone tools found in Penghu and southern Taiwan. During this trip, Tsang discovered another two lithic workshop sites, at Tung-hu and Hsi-pei-wan. These two sites are very large in size, with a large number of stone materials, wastes, finished products and stone hammers scattered on the surface. They are the largest lithic workshop sites ever found in the Taiwan region. Based on the materials collected from these sites, Cheng-hwa Tsang and Hsiao-chun Hung have conducted a preliminary study of the lithic technology and discussed problems related to prehistoric lithic manufacturing activities on Chi-mei Island.
