Data Brief. 2019 May 22;25:103848. doi: 10.1016/j.dib.2019.103848. eCollection 2019 Aug.
The data presented in this article are related to the research paper entitled "Pyrometamorphic aureoles of Cretaceous sandstones and shales by Cenozoic basic intrusions, NE Brazil: Petrographic, textural, chemical and experimental approaches" Souza et al., 2018. Here, we report the complete data set for natural minerals and rocks as well as for experimental runs. These data include detailed oxide composition of minerals and glassy groundmass of the samples studied from electron microprobe and scanning electron microscopy analyzes. Rock samples and minerals are separated according to the protolith (sandstone, shale), pyrometamorphic rock (dark and light buchites, and silica-rich types), intrusion (basalt, diabase) that induced the pyrometamorphic events, and experimental results (microphenocrysts, glass).
