Location and information files

These are the files containing other information used for this thesis from which the various maps showing locations of quarries, samples, and artefacts were created. Each is in .csv format. The files are: Artefact data file.csv Quarries.csv Trace element map sample locations.csv Artefact data file.csv: On line databases for 10 Swedish museums were searched for their steatite artefacts, and the information was compiled to this file. For those artefacts where the location was given only in the form of a place name I consulted online maps, including the Swedish National Map service, https://minkarta.lantmateriet.se/ and https://www.google.com/maps to determine a latitude and longitude for the address/location described. If the exact location could not be determined, or was not listed, but the database listed the parish in which it was found, then the location of the parish was determined from https://socknar.se/, and the location of the parish church was recorded. If there was not even a parish listed, then the approximate centre of the province was recorded. These three levels of accuracy for the location are recorded under the variable name “accuracy”. Quarries.csv: The data for these steatite quarry, outcrop, and prospect locations was primarily obtained from the Norwegian Geological Survey (https://geo.ngu.no/kart/mineralressurser_mobil/) for the quarries located in Norway, and the Swedish Geological Survey (https://apps.sgu.se/kartvisare/kartvisare-malm-mineral.html) for those located in Sweden. This information was supplemented with some data from my own field work when collecting samples, and from the Swedish national archaeological database (https://app.raa.se/open/fornsok/). Trace element map sample locations.csv: This file contains information specific to the samples analysed with LA-ICP-MS for this thesis, with location and geologic information coming from the quarry locations file (see above), and the information pertaining to the sample and trace-element composition map number, which epoxy mount it is in, and the date of analysis is recorded from working notes.
