Abstract

Ile-Ife in southwestern Nigeria is rich in art and craft traditions, most especially iron smelting. The town hosts hundreds of smelting sites with little or no archaeological record. Archaeo-geophysical prospection of a suspected smelting site in Ile-Ife involved the magnetic and electrical resistivity geophysical methods and archaeological excavation with the aim to identify its buried artefacts/features and date the site. The geophysical investigations located a circular/oval-shaped dipolar magnetic anomaly that coincided with a high resistivity zone, typical of a heat-impacted furnace or a slag trench. Iron slag, tuyere, fired clay furnace fragments, and charcoal were recovered from the pits excavated at the locations of the geophysical anomalies. Smelting activity at the site, from dated charcoal, took place at some point between the 13th-15th centuries AD, a middle to late age in Africa’s history of iron smelting. This study, therefore, validated the examined site as an ancient iron smelting site and situated its place in the archaeological history of iron smelting.

尼日利亚西南部Ile Ife的Ife City Grand Resort炼铁遗址的考古地球物理调查

尼日利亚西南部的Ile Ife有着丰富的艺术和工艺传统，尤其是炼铁。该镇拥有数百处冶炼遗址，几乎没有或根本没有考古记录。Ile Ife一处疑似冶炼遗址的考古地球物理勘探涉及磁阻和电阻率地球物理方法以及考古挖掘，目的是确定其埋藏的文物/特征并确定遗址的年代。地球物理调查发现了一个圆形/椭圆形偶极磁异常，该异常与高电阻率区重合，典型的是热冲击炉或渣沟。从地球物理异常位置挖掘的坑中回收了铁渣、风口、烧制的粘土炉碎片和木炭。该遗址的冶炼活动是用年代久远的木炭进行的，发生在公元13-15世纪之间的某个时期，这是非洲炼铁史上的中晚期。因此，这项研究证实了被检查的遗址是一个古老的冶铁遗址，并确定了它在冶铁考古史上的地位。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
