高温敏感性（HT-χ）数据在地球、行星和环境科学中经常测量，以快速识别自然系统的磁矿物学。对这类数据的解释可能很复杂。虽然有些矿物在加热时相对不会发生变化，并且很容易通过居里或纳姆伊尔温度来识别，但其他常见的磁相，例如硫化铁，对加热非常不稳定。这使得HT-χ解释具有挑战性，特别是在多矿物学样品中。在这里，我们报告了主要在伦敦帝国理工学院测量的天然样品中发现的常见磁性矿物的HT-χ数据的回顾。除了多相HT-χ数据的解释示例外，我们还展示了“近纯”自然样品的示例。我们希望这篇论文能成为HT-χ数据解释的第一篇参考论文。
High-temperature susceptibility (HT-χ) data are routinely measured in Earth, planetary, and environmental sciences to rapidly identify the magnetic mineralogy of natural systems. The interpretation of such data can be complicated. Whilst some minerals are relatively unaltered by heating and are easy to identify through their Curie or Néel temperature, other common magnetic phases, e.g., iron sulphides, are very unstable to heating. This makes HT-χ interpretation challenging, especially in multi-mineralogical samples. Here, we report a review of the HT-χ data measured primarily at Imperial College London of common magnetic minerals found in natural samples. We show examples of “near pure” natural samples, in addition to examples of interpretation of multi-phase HT-χ data. We hope that this paper will act be the first reference paper for HT-χ data interpretation.
