LGRB-BW KMR50_AS: Reliability of raw material deposits: Oil shale

The certainty of the oil shale deposits ranges from 1 – deposits proven (the occurrence of building-worthy areas is very likely) to 4 – occurrences suspected (existence of constructional areas uncertain). Further information on the certainty of statements can be found on LGRB Knowledge: https://lgrbwissen.lgrb-bw.de/rohstoffgeologie/rohstoffe-des-landes#paragraphs-item-7443油页岩矿床的确定性分级范围为1至4级：1级为已探明矿床（具备符合建筑开发要求的区域的存在可能性极高），4级为疑似存在矿床（符合建筑开发要求的区域的存在尚不明确）。如需了解更多关于陈述内容确定性的相关信息，可查阅LGRB知识库：https://lgrbwissen.lgrb-bw.de/rohstoffgeologie/rohstoffe-des-landes#paragraphs-item-7443
