The Ries impact structure in Southern Germany is one of the best-preserved impact structures on Earth. Melt-bearing impact breccia appears in a variety of well accessible exposures around the inner ring up to 10 km beyond the crater rim (so-called outer suevite) overlying a ballistically ejected lithic breccia (so-called ‘Bunte Breccia’). Occasionally individual melt bombs occur in the ‘Bunte Breccia’. Coherent impact melt rock outside the inner crater is located in the eastern megablock zone (Stöffler et al., 2013 and references therein).This data set comprises major and trace element geochemistry of samples from eight outer suevite exposures, one impact melt rock exposure, and one melt bomb of the Ries impact crater. Two analytical method approaches were performed: i) in-situ analysis using electron microprobe (EMP) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and ii) analysis of whole-rock, melt separates, and suevite matrix separates using X-ray fluorescence (XRF), and inductively coupled plasma atomic emission spectroscopy (ICP-AES)/ inductively coupled plasma mass spectrometry (ICP-MS).
This data set comprises major (XRF) and trace (XRF, ICP-MS, ICP-AES) element geochemistry of 185 samples of crystalline target lithologies of the Nördlinger Ries impact crater in Southern Germany.
The sample set was originally collected by D. Stöffler for the investigation of shock metamorphism and Schmitt and Siebenschock for a research project on the occurrence of impact diamonds in the Nördlinger Ries crater. The data are supplementary material to Siegert et al. (2017, http://doi.org/10.1130/G39198.1) and are supplemented by by geochemical data of melt-bearing impact breccia (suevite) from the research drill core FBN 73 of the Ries impact crater (Siegert et al., 2017; http://doi.org/10.5880/fidgeo.2017.002. More information about sample preparation, methodology and precision expectations are given in the Explanatory File.
Repository samples and thin sections are available for more or less the whole sample set of Stöffler and selected samples from Schmitt and Siebenschock, and are stored in the impactite collection of the Museum für Naturkunde Berlin.
