When was Cornish tin mined and processed in prehistory?

这项研究的目的是利用环境化学特征和未受干扰的Bodmin Moor和Dartmoor泥炭岩芯的放射性碳测年，记录整个史前康尼什锡矿开采的扩张和收缩。锡是从哪里来生产青铜的，这是古代世界的一大谜团。残缺不全的文本，大约。公元前300年，希腊探险家皮西亚斯认为，西地中海的Phocaean贸易商与康沃尔有联系，康沃尔是迄今为止欧洲/中东最丰富的锡矿来源，他们声称矿石是开采和冶炼的。几乎没有考古证据支持这一说法，也没有考古证据支持这一说法，或者以前或后来对康尼什锡矿资源的史前开采。涉及金属冶炼的古代活动通过泥炭和冰芯中的大气沉积按时间顺序保存下来。本文拟对位于康沃尔/德文郡锡矿中心的Bodmin Moor和Dartmoor原状泥炭岩心中的锡和其他伴生/共生元素(砷、铜、铅、银等)进行剖面分析。在这些沼泽上未受干扰的泥炭矿藏已经被发现。放射性碳测年将被用来测定泥炭金属剖面中的峰谷。还将进行铅同位素分析，以提供进一步的诊断特征，以区分当地的矿石冶炼活动和长途运输的矿石。这样，就可以确定该地区的史前采矿/冶炼活动。

The objective of this study is to record the expansion and contraction of the Cornish tin exploitation throughout prehistory using environmental chemical characterization and radiocarbon dating of undisturbed Bodmin Moor and Dartmoor peat cores . Where tin was sourced for the production of bronze is one of the great mysteries of the ancient world. Fragmentary texts, circa. 300 B.C. of the Greek explorer Pytheas suggest that the Phocaean traders of the Western Mediterranean where in contact with Cornwall, by far the most abundant tin ore source in Europe/Middle East, stating that ore was mined and smelted. Virtually no archaeological evidence has been unearthed to provide factual evidence to support this claim, or of previous, or later pre-historical exploitation of Cornish tin sources. Ancient activity involving metal smelting is preserved chronologically through atmospheric deposition in peat and ice cores. It is proposed here to profile tin and other associated/co-occurring elements (arsenic, copper, lead, silver etc) undisturbed peat cores from Bodmin Moor and Dartmoor, both situated in the heart of the tin deposits of Cornwall/Devon. Undisturbed peat deposits on these moors have already been identified. Radiocarbon dating would be used to date peaks and troughs in peat metal profiles. Lead isotope analysis will also be conducted to provide further diagnostic characterisation, to distinguish between local ore smelting activity and that transported long distance. In this way prehistoric mining/smelting activity in this region will be ascertained.
