Raw Data for: "Multitechnique Characterization of Secondary Minerals near HI-SEAS, Hawaii, as Martian Subsurface Analogues"
This repository contains raw and processed data for the published paper: "Multitechnique Characterization of Secondary Minerals near HI-SEAS, Hawaii, as Martian Subsurface Analogues" by Mulder et al. (2023) in Scientific Reports. The dataset comprises XRF data from basalts and XRD, SWIR, FTIR and SEM data from secondary minerals in lava tubes on Mauna Loa, Hawaii. This data was used to determine the mineralogy and distribution of secondary minerals observed in lava tubes. Hyperspectral images have been used to map mineral distribution on the basaltic surfaces as analogue for Martian environments. SEM images show the internal morphology and mineralogy of silica and calcite coralloid speleothems.
Steps to reproduce
The Authors refer to the publication: "Multitechnique Characterization of Secondary Minerals near HI-SEAS, Hawaii, as Martian Subsurface Analogues" by Mulder et al. (2023) for the methodology of the different analytical techniques used in this study. Short Wave Infrared (SWIR) data: This data can be opened with the software Hyperspectral Python 3 (HypPy3) and ENVI software made available by the University of Twente (http://hyppy.is-great.org/index.html). Fourier Transform Infrared (FTIR) data: The dataset contains Attenuated Total Reflectance (ATR) and sphere raw data files, which can similarly be opened by HypPy3 software. Furthermore, the dataset contains processed spectra of the samples, which have been made in duplicates. X-Ray Diffraction (XRD) data: This dataset contains .xrd files of the secondary minerals, which can be opened by compatible XRD software. The dataset also contains excel files with the angles, counts and d-values of every samples with plotted diffractograms. Scanning Electron Microscopy (SEM) data: .doc files containing element compositions and elemental maps and SEM images. X-Ray Fluorescence (XRF) data: Excel file containing the major element data of the basaltic samples.
