磁力测定用于查找考古特征如石头墙或古老的壁炉。但它通常不能用于考古勘察地区基岩强磁。假设玄武岩-镇附近是很常见的。平均铯蒸气磁强计,必须多厚土,这样我能找到的高磁等功能仍然燃烧wattle-and-daub房子或一个铁仓库吗?如果操作之间的断层附近的磁性和非磁性岩石,如何远离磁性岩石可以找到弱磁情况下扰动土吗?
编辑:我希望近似的答案。答案我希望可以开始:“铁比玄武岩磁性,所以几公斤的铁(或铁生锈)可以发现甚至低于一米condidtions X下的基石之上,否则几米。非常小的铁项目和成堆的燃烧土壤通常需要几十米……”I just guess all the facts, I don't know, I'm just an archaeologist with no background i geophysics. The aim of this edit is to emphasize that I don't need exact numbers, but I need an idea which numbers might be exact and which are likely to be completely wrong.
