This project is positioned at the intersection of geology and archaeology. It aims to reconstruct the origin of the raw material used for the formation of picture stones from ca. 400 to 1100 AD on Gotland (Sweden). Based on an extensive dataset of stable carbon, oxygen and strontium isotope values from all lithological units on Gotland, several building stones, most of which are now in the museums in Visby and Stockholm, will be analysed and assigned to a specific rock unit on the island of Gotland. The following hypotheses will be tested: (a) the geochemical "Fingerprint" of the building stones allows for a precise attribution to the respective geological rock unit, (b) during different historical epochs specific rock types were preferred, (c) if necessary long transport distances were accepted, (d) the facies type and thus the homogeneity of the rock was an important factor for the choice of the raw material, and finally (e) the distribution dynamic of the picture stones is related to the geological bedrocks.

该项目定位于地质学和考古学的交叉点。它的目的是重建用于形成图画石的原材料的起源。公元400年至1100年在哥特兰（瑞典）。根据哥特兰岛上所有岩石单位的稳定碳、氧和锶同位素值的广泛数据集，将对几种建筑用石头进行分析，并将其分配给哥特兰岛上的一个特定岩石单位，其中大部分石头现在存放在维斯比和斯德哥尔摩的博物馆里。将检验以下假设：（a）建筑石材的地球化学“指纹”允许精确地归属于相应的地质岩石单元，（B）在不同的历史时期，特定的岩石类型是优选的，（c）如果需要，可以接受长的运输距离，（d）岩石的相类型和均匀性是选择原材料的重要因素，画石的分布动态与地质背景有关。
