Abstract
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.
The matrix mineralogy has been studied and the main minerals are
quartz, potash feldspar, plagioclase and biotite. As accessory minerals
mainly amphibole, sphene, epidote, apatite and opaque minerals are found.
This paper is a compilation of modern chemical analysis on Karlshamngranite
from various sources, recalculated norms on a common basis,

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.
The matrix mineralogy has been studied and the main minerals are
quartz, potash feldspar, plagioclase and biotite. As accessory minerals
mainly amphibole, sphene, epidote, apatite and opaque minerals are found.
This paper is a compilation of modern chemical analysis on Karlshamngranite
from various sources, recalculated norms on a common basis,
matrix mineralogy investigations and statistical calculations. The
results are presented in various diagrams and tables.

In the town of Ronneby the leucogranite is found as a red mediumgrained
rocktype, at some places with a well developed structure pronounced
by elongated quartz and feldspar grains. It crops out as smaller
bodies from dm-large patches to 7-800 m large massives with sharp intrusive
margins to the neighbouring Karlshamn granite. It consists to more
than 95% of quartz, plagioclase and potassium feldspar and carries as
accessorial minerals mainly biotite, opaque minerals and sphene.
Chemical analysis has been done and the results are, together with
the Karlshamn granite analysis, shown in different diagrams. In these
diagrams, trends can be seen which can be interpreted as differentiation
trends. If the leucogranite is an anatectic granite formed by partial
melting of the Karlshamn granite or the end of a differentiating
Karlshamn granite magma has been considered but this investigation has
not led to a definit conclusion. (Less)
