Supplements related to the paper: "Contrasting TiO2 compositions in Early Cenozoic mafic sills of the Faroe Islands: an example of basalt formation from distinct melting regimes"

The data presented here represent six (6) supplements related to a manuscript in igneous petrology: "Contrasting TiO2 compositions in Early Cenozoic mafic sills of the Faroe Islands: an example of basalt formation from distinct melting regimes". This manuscript endeavours to interpret processes in the upper mantle and in the Earth's crust involved, when basaltic magmas formed and finally solidified in the form of basaltic sills in the uppermost crust of the Faroe Islands. We detect the nature of the most likely mantle sources (geochemically and isotopically) and interpret relevant processes such as crystal fractionation, mineral accumulation and minor crustal contamination during evolvement of the magmas that were eventually emplaced as basaltic sills in the Faroese area. The supplements presented here involve petrographic data, geochemical data, isotopic data, analytical techniques and so forth. The supplements thoroughly support the inferences and interpretations put forward in the main manuscript.

本文提供的数据为一篇火成岩石学领域学术论文的6份补充材料，该论文题为《法罗群岛早新生代基性岩床的TiO₂组分差异：源自不同熔融机制的玄武岩形成实例》。该研究旨在阐释法罗群岛最上部地壳中，玄武质岩浆形成并最终以玄武岩床形式固结过程中所涉及的上地幔与地壳演化过程。本研究从地球化学与同位素视角，查明了最可能的地幔源区属性，并阐释了法罗地区玄武岩床侵位过程中，岩浆演化阶段所经历的结晶分异、矿物堆积及微弱地壳混染等相关作用过程。本次提供的补充材料涵盖岩石学数据、地球化学数据、同位素数据及分析测试技术等内容，可充分支撑主论文中提出的各项推论与阐释结论。
