   Sammanfattning : The Karlshamn-granite is a greyish red to reddish grey mediumgrained rock with considerable amounts of potash feldspar megacrysts. It covers large areas of Blekinge and northeastern Scania. The granite appears as post-orogenic intrusive granitoid plutonics of very varying size and is considered to belong to the youngest granitoids in this area. LÄS MER
