  <dc:description>SEM-based automated mineralogy was performed on polished thin sections from 20 different samples from the “Granittagebau Rauschwitz-Kindisch” (Upper Lusatia, Germany).

This quarry is frequently cited in geological literature as the “Kindisch Quarry” or “Steinbruch Kindisch.” The rocks are part of the Cadomian Lusatian Granodiorite Complex (Lusatian Massif).

The basement of the Lusatian Massif consists of monotonous, flysch-like, Precambrian greywacke and pelite sequences (Kröner et al., 1994; Linnemann et al., 2010). These rocks are primarily found in the northern part of the massif and consolidated during the Cadomian orogeny (approximately 570–540 million years ago).  The granodiorites and greywackes formed around 540–530 Ma (Linnemann 2007; Tichomirowa et al. 2001; Tichomirowa 2002).

The samples were analyzed using a Mineral Liberation Analyzer (MLA) with SEM-based automated mineralogy at the Helmholtz Institute Freiberg for Resource Technology. The MLA consists of a FEI Quanta 650F field emission scanning electron microscope (SEM) with two Bruker Quantax X-Flash 5030 energy dispersive X-ray (EDX) detectors, as well as FEI's MLA Suite v. 3.1.4.686 software for data acquisition. MLA identifies mineral grains based on backscattered electron (BSE) image segmentation and collection of EDX spectra of grains distinguished in BSE imaging mode. However, boundaries between two grains of the same mineral are not visible because their BSE intensities are identical. The collected EDX spectra are then classified using a list of mineral spectra collected for granitic rocks and adapted to the mineralogical characteristics of the investigated granodiorites. More detailed information about the functionality of the MLA system can be found in Bachmann et al. (2017).

A resolution of 3×3 µm per pixel was used. The measurements were taken during two measurement periods in December 2023 and January 2024 under identical conditions. The data are therefore summarized here and are not presented broken down by measurement date.

The data is structured as follows:


	The main results are available as BMP images with a spatial resolution of 3 µm × 3 µm per pixel.
	The *_MINERAL_SAMPLE.bmp files contain the assigned mineral information. The corresponding legend can be found in Granite_Legend.png.
	The *_BSE_SAMPLE.bmp files contain the results of the backscattered electron contrast analysis as grayscale values.
	The “Samples” folder contains the original measurement data for each individual sample, along with the GXMAP data compiled for each sample in the ‘GXMAP’ subfolder, including the time of measurement.
	The “Processing Scripts” folder documents the individual scripts used in the automated workflows.
	The “Mineral_List” folder contains the adapted mineral list that was used.
