基于磁性参数和粒度指标分析的良渚古城城墙土物源探讨

Liangzhu culture is one of the Neolithic culture in China, is widely distributed in the middle and lower reaches of the Yangtze River, Taihu Lake area, in Liangzhu Town, Yuhang District, Zhejiang Province, the excavations of Liangzhu ancient city can link human activities to the environment between climate, This article is mainly to study the The walls of the ancient city、Nearby mountain, described in the wild formation based on the analysis of laboratory experiments, mainly through environmental magnetic particle size indicators on the source of the ancient city wall soil, it can be drawn by analyzing: the walls soil mass magnetic susceptibility, SIRM, HIRM frequency magnetic susceptibility Χfd parameters around a small hill the Majinkon Mantoushan column samples have good correspondence between its significant ,but difference between magnetic mineral grain size characteristics and particle size analysis found that the magnetic parameters of the area by the size of the magnetic minerals contribution proceeds, deposited soil is clayey silt, smaller particle size and more uniform
