Whole rock and mineral separate nitrogen concentration and isotopic data for meta-ultramafic rocks

Nitrogen concentrations and 𝛿15N compositions for nine whole rock and eighteen mineral separate samples. Samples are serpentinites, talc schists and a chlorite schist from Syros, Greece and New Caledonia, representing subducted and exhumed meta-ultramafic lithologies. These data were collected to characterize the bulk rock and phyllosilicate mineral compositions.

本数据集包含9件全岩样品与18件单矿物分离样品的氮浓度及δ¹⁵N（δ¹⁵N）组成数据。样品包括蛇纹岩、滑石片岩及1件绿泥片岩，均采自希腊锡罗斯岛与新喀里多尼亚，代表俯冲折返型超镁铁质变质岩岩性。本次数据采集旨在表征全岩与层状硅酸盐矿物的地球化学组成特征。
