- Koralpe
The Koralpe
, also referred to as "Koralm", is a mountain range in southern
Austria which separates easternCarinthia from southernStyria . Running from north to south, it drains to the riverLavant in the west, and to the river Sulm in the east. Its highest elevation (2,140 meters) is the Große Speikkogel, a popular hiking destination and also a node for militaryradar airspace surveillance. In the south, towards theSlovenia n border, it is contiguous with the Poßruck mountain range.The Koralpe consists mostly of
metamorphic rock , of which some parts are of considerable interest to geologists and to collectors of semi-precious stones. In and around the "Weinebene" (also a popular recreational and hiking area) there are pegmatitic strata which contain significant amounts ofSpodumene , making this area the largest knownlithium deposit in Europe.Quartz andfeldspar , together with the dense forests, provided the basis for aglass andporcelain industry in earlier times.The Koralm tunnel, a major construction site, is the centerpiece of the "Koralmbahn", a
high-speed rail project which will provide the first direct rail link between the provicial capitals ofKlagenfurt andGraz .
