| Zusammenfassung |
| Several activities and responsibilities of the Geological Survey of Sweden (SGU) are related to the work of the newly formed international Heritage Stone Task Group (HSTG) for designating historically important stones. SGU is among other things a referral organization, frequently dealing with the preparation of statements in connection with the quarrying permit applications of stone producers. When preparing these statements, SGU takes into account a number of parameters, e.g. the importance for local and regional business development, historic importance, area of occurrence, quality of the geological documentation of the stone type, peculiarities of the stone types and technical properties relevant for the intended use. Traditionally, SGU has not worked with bedrock mapping looking at the potential of natural stones production but more commonly looking at the potential production of aggregates, industrial minerals and metals. The competence is, therefore, presently being built up with new databases over important natural stone types and definition of criteria for their selection etc. In this respect the criteria defined by the HSTG provide important help.
This work goes hand in hand with the task of proposing stone-deposits and quarries of “national interest”. The criteria for selection of a stone type, quarry etc as one of national interest are currently being revised. SGU plays an important role in this work. However, the final decision and appointment lies in the hands of the Swedish Board of Housing, Building and Planning (Boverket), an authority dealing with sustainable land use and regional development, town and country planning. Boverket supervises how the planning legislation is handled by the municipal authorities and the county administrative boards. The two latter organizations are those in charge of giving extraction permits for stone quarrying.
The “Hallandia gneiss”, of SW Sweden, is described as a case story and presented in this paper.
