This specimen has abundant crystals of richterite to 0.6 cm in length set in
calcite
matrix.
This specimen has a fairly thick (2cm) layer of white
calcite
with abundant honey coloured crystals of richterite. This mineral was first
found at Långban and occurs in many colours and chemical variations. The
largest crystals on this specimen are a little over 1 cm in length.
This specimen was identified by Flink as being "red hornblend". I have my
doubts and believe that the red crystals may be
rhodonite
or more likely richterite. The prism faces are striated so richterite is a
better fit. It was not analyzed however. The crystals are frozen in
calcite
matrix and reach up to 0.7 cm in length.
Crystals of richterite to 0.5 cm are frozen in
calcite
matrix. Ex.
