Abstract

Identification of magnetic minerals in rocks and other natural substances (sediments, ashes, soils, etc.) is important in Earth sciences. Such identification often uses a measurement of the IRM (isothermal remanent magnetization) acquisition curve that in turn provides the coercivity spectrum of the sample. In this study, MAX Unmix web-based application was used to unmix the coercivity spectrum of 13 natural samples to obtain their coercivity components. Digitized IRM acquisition data were inputted into the application, then adjusted specific parameters to obtain a best-fit coercivity spectrum revealing coercivity components. As a result, two to three components are generally identified for each sample. MAX Unmix application is highly recommended in future studies requiring the identification of magnetic minerals in natural substances.
利用maxunmix网络应用程序识别天然物质中的矫顽力分量
鉴定岩石和其他自然物质(沉积物、灰烬、土壤等)中的磁性矿物在地球科学中是重要的。这种鉴定通常使用IRM(等温剩余磁化)采集曲线的测量,从而提供样品的矫顽力谱。本研究利用基于web的MAX Unmix应用程序对13种天然样品的矫顽力谱进行解混,得到其矫顽力分量。将数字化的IRM采集数据输入到应用程序中,然后调整特定参数,以获得显示矫顽力成分的最佳拟合矫顽力谱。因此,每个样品通常鉴定出两到三种成分。强烈建议在未来需要鉴定天然物质中磁性矿物的研究中使用MAX Unmix。
