GLOBAL CHANGE: THE GEOLOGICAL SURVEY OF CANADA PERSPECTIVE

Geological processes are fundamental to the understanding of Global Change and the geological record provides a baseline against which to assess the nature and significance of contemporary global change (Price 1986)     

Nabataean finds from Thaj and Qatif

Ties between the Nabataean area of northwestern Arabia and southern Palestine, and the northeastern portion of the Arabian peninsula have been discussed for some years. The material evidence of such ties is meagre, but nonetheless important. Two Nabataean coins from Thaj and one from Qatif are presented here, along with a painted Nabataean sherd from Thaj. Their implications are treated briefly.     

Geochemical evidence for the manufacture,logistics and supply‐chain management of Emperor Qin Shihuang's Terracotta Army,China

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce .
