河南新密市新砦城址中心区发现大型浅穴式建筑

Large-sized Shallow-pit-style Building Discovered in the Central Area of the Xinzhai City-site in Xinmi City,Henan

中国社会科学院考古研究所与郑州市文物考古研究所合作开展的中华文明探源工程首批启动项目之一“河南省新密市新砦遗址聚落布局与内涵研究”，近年来田野工作不断取得新的进展。2002年发现的位于遗址中心区的“大型建筑”，经2003、2004年的持续发掘和2005春季的解剖，目前已基本可以肯定这是一处新砦期晚段的多次使用的大型浅穴式露天活动场所。其规模宏大，居同时期同类建筑之首。

In the spring of 2002, at the preparatory research and the first stage of the project of studying the origins of Chinese civilization, the Xinzhai Subject Group discovered the remains of a large-sized building on the Xinzhai city-site, a little north of the center of the ＂inner sub-city＂, at the highest spot of the site. Through continuous excavation in 2003 and 2004 and selective digging in the spring of 2005, it has been clarified that the building has a L-shaped plan with the major axis of the main part pointing to the west and east. Measuring 92.6 m in remaining length from the west to the east and 14.5 m in remaining width, and reaching above 1,000 sq m in total area. Based on an original west-to-east road, it was extended to the two sides of the road, first of all, by digging an extensive shallow ＂foundation-pit＂ below the then ground, and then by adding clay strips and severalcourse ＂narrow walls＂ to the pit walls. Correspondingly, the pit bottom was made into a stamped flat floor formed of several layers of bedded-down earth some five to ten cm in thickness. No post-holes were found in the periphery of the pit and inside it, while extensive traces of water-logged depressions were seen clear on the stamped floor. These suggest that very possibly the pit was originally a large-sized shallow-pit-style open-air building.
