Folgheraiter建议超过一个世纪前，烤材料原则上可以用来研究变化的地球磁场强度在过去虽然他预见到巨大的困难。在过去的世纪里，在为利用考古和地质材料研究磁场强度的变化奠定理论基础方面取得了巨大的进展。沿着更好的理论基础，实验设计也得到了改进。在过去的十年中，有爆炸性的论文提出的数据，随着时间的推移，使用火成岩和沉积记录的古强度的变化。在这一章中，我们将探讨在火成岩和沉积环境中的古强度实验的理论基础，回顾现有的数据，并强调当前感兴趣的主题。
Folgheraiter suggested over a century ago that baked materials could in principle be used to study variations of the Earth’s magnetic field intensity in the past although he foresaw great difficulties. Over the last century, enormous progress has been made in laying the theoretical foundations for using archaeological and geologic materials to study variations in the strength of the magnetic field. Along with better theoretical foundations have come improvements in experimental design. Over the last decade, there has been an explosion of papers presenting data concerning variations in paleointensity through time using both igneous and sedimentary records. In this chapter, we will explore the theoretical basis for paleointensity experiments in igneous and sedimentary environments, review the existing data, and highlight current topics of interest.
