Ceramics from the late prehistoric periods at Sos Höyük, in Eastern Anatolia, located along a thoroughfare that connects the Trans-Caucasus, Iran and central Anatolia, were subjected to petrographic and X-ray fluorescence analysis in order to characterise the clay groups, with a view to determining provenance and production patterns. Dominated by Kura-Araxes Ware, the data from the sequence at Sos Höyük were compared with the previous studies from the neighbouring regions to understand commonalities in pottery production. The analyses reveal a local production of vessels, most probably for household use. Although Sos Höyük potters shared similarities in the procurement pattern of raw clays and production technique with their neighbours, differences can be also recognized. 相似文献

Micro-fabric characteristics and optically stimulated luminescence (OSL) dating results are presented to discuss the controlling
agents and timing of beachrock cementation on the fresh-water Iznik Lake shoreline. The beachrocks are made up of grain-supported
polygenic conglomerate containing 20.42% carbonate with encrusted grains, basically as micrite coatings, isopachous aragonite
rims, cryptocrystalline void fills and meniscus bridges. The optical ages of twelve samples yielded ages that range from 4.226±0.569
ka on the lowermost beds to 0.706±0.081 on the uppermost. This is the first report of precipitation of marine-like cements
in Iznik Lake. The abundant aragonite-dominated cement is likely indicative of precipitation-prone dry evaporative conditions
from the climatic optimum to the last millennia. 相似文献

Geographic and Network Neighbors: Spillover Effects of Telecommunications Infrastructure 总被引:3,自引:0,他引:3
This paper tests for spatial spillover effects of state-level telecommunications infrastructure investment on state output, using panel data for 48 U.S. states from 1970 through 1997. As information and communication technologies support more industrial locational freedom, states may use telecommunications infrastructure investment as a competitive tool for attracting factors of production. In a production-function framework, this effect would manifest itself as a negative output spillover effect from telecommunications infrastructure investment. Findings indicate that a state benefits from its own telecommunications infrastructure, but telecommunications investment by other states has a negative impact on its output growth path, and proximity amplifies this negative spillover effect. 相似文献
