AMS data of the Santa Angélica pluton

This dataset is part of the work "Magnetic fabric and geochronology of a Cambrian “isotropic” pluton in the Neoproterozoic Araçuaí orogen". Such work presents results of an integration of U-Pb SHRIMP and a detailed anisotropy of magnetic susceptibility (AMS) study to determine the emplacement mechanisms of the Santa Angélica. This pluton was emplaced at the mid-crustal section of the Araçuaí orogenic system, and is located along its southern toe. Its internal fabric pattern will provide information on the final deformation partitioning at the waning stages of mountain building across this crustal level that is presently inaccessible in modern orogens.
In this dataset we filed anisotropy of magnetic susceptibility (AMS), thermomagnetic experiments and anisotropy of anhysteretic remanence magnetization (AARM) data.

本数据集隶属于《新元古代阿拉库阿伊造山带中新寒武世“各向同性”岩体的磁结构及地质年代学》这一研究成果。该研究通过整合U-Pb SHRIMP技术和详细的磁化率各向异性（AMS）研究，揭示了圣安热利卡岩体的就位机制。该岩体位于阿拉库阿伊造山带的中部地壳部位，沿其南缘延伸。其内部结构模式将为研究在造山运动晚期、跨越当前无法在现代造山带中观察到的地壳级别的最终变形分配提供信息。在本数据集中，我们收集了磁化率各向异性（AMS）、热磁实验以及各向异性无阻尼剩磁化率（AARM）数据。
