Origin of rare-element-mineralized Damara Belt pegmatites: A geochemical and light stable isotope study

Supplementary major and trace element data, and O- and H-isotope data. Trace and major element data from whole-rock pegmatite samples collected from the wall zone of zone pegmatites, and near the contact of unzoned pegmatites with country rock. These were analysed by ICP-MS. Major element data were obtained for the same samples by XRF. O-isotope data were collected from quartz and feldspar separates. Where possible, large mnomineralic samples were collected and analysed. H-isotope data are from muscovite, and a single biotite sample (VALG-022).本数据集包含补充性主量元素（major element）、微量元素（trace element）数据，以及氧同位素（O-isotope）与氢同位素（H-isotope）数据。全岩伟晶岩（whole-rock pegmatite）样品的微量元素与主量元素数据采自分带伟晶岩的边带（wall zone），以及未分带伟晶岩（unzoned pegmatites）与围岩（country rock）的接触带附近。此类样品通过电感耦合等离子体质谱法（ICP-MS）完成微量元素分析，同时采用X射线荧光光谱法（XRF）对同一样品开展主量元素测试。氧同位素数据采自石英（quartz）与长石（feldspar）单矿物分离样；在条件允许的情况下，采集并分析了大型单矿物样品。氢同位素数据来自白云母（muscovite）样品，以及单个黑云母（biotite）样品（VALG-022）。
