History of Emerald Mining in the Habachtal Deposit of Austria, Part II 奥地利Habachtal矿床祖母绿开采史(二)

{"title":"History of Emerald Mining in the Habachtal Deposit of Austria, Part II","authors":"K. Schmetzer","doi":"10.5741/gems.58.1.18","DOIUrl":"https://doi.org/10.5741/gems.58.1.18","url":null,"abstract":"Published information about the history of the Habachtal emerald mine in the era between War I and War II is limited and superficial. Subsequent to the departure of Emerald Mines Limited, the English company that had owned the property since 1896, the Habachtal mine was owned or controlled by Austrian, Swiss, Italian, or German companies or citizens. The names of various companies and individuals who were actively mining for some time in the Habach Valley are mentioned in numerous papers, books, or newspapers. The relationships between them and the property owners mentioned in files of the Mittersill land registry office are frequently unknown and the reasons for numerous transitions of ownership, followed by changes of the mining entities that operated the deposit, are not clearly seen. Using a wide selection of materials from Austrian and German archives, largely unpublished, the author seeks to trace the history of the Habachtal mine through this period and to fill the gaps left by existing publications. Activities and events after 1945 and the present situation are also briefly described.","PeriodicalId":354281,"journal":{"name":"Gems & Gemology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131340482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
