Abstract

In this article, the geochemical data of a ~900 Ma mafic sill from Xuzhou, North China are reported. These datasets include 37 whole-rock major and trace element data, and 21 major element data on plagioclase, 20 major element data on clinopyroxene crystals, 10 major element data on apatite crystals, 7 major element data of preserved coexisting titano-magnetite and ilmenite grains, 36 major element data on different types of ilmenite crystals, 13 major element and 11 trace element data on titanite. These data are associated with Su et al. “Petrogenesis of a ~900 Ma mafic sill from Xuzhou, North China: Implications for the genesis of Fe-Ti-rich rocks” (Su et al., 2018), and in which their characters and variations were interpreted and discussed.

Summary

Sampling

A total of 38 samples were collected systematically with a constant spacing of $ 0.5 m from the top to the bottom of the Niutishan mafic sill. The true stratigraphic position and the distance between samples were corrected based on the average local dip (17° SE). The real outcrop thickness of this sill is $22 m, and the top surface was set to ‘0 m’. The erosion surface of sample was carefully removed. All analytical procedures were accomplished at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS). Comby-shape 8-ilm-f1 12-ilm-f4 15-ilm-f2 20-ilm-f1 29-ilm-f1 33-ilm-f1 36-ilm-f2 39-ilm-f1.
