Fig. 8 The Kopingsklint Formation in two rock-sections north-east of cape Horns Udde. For the
situation of these sections see localities 1 and 2 of fig. 5.
Legend: 1 = slightly glauconitic black shale. 2 = glauconite sand with a black shale matrix. 3
= highly calcareous glauconite sand with a cement of sparry calcite, often arranged in
rosette-like structures. 4 = marl. 5 = fossiliferous limestone. 6 = glauconitic limestone. 7 =
disconformities.
K means the Kopingsklint Formation.
k or a-d indicates that the member is considered to be most typical at
Kopingsklint or along the coast between Aleklinta and Djupvik respectively.
1,2, 3 indicates the order of superposition from below upwards.
The typical development of this formation is shown in fig. 6. The Kopingsklint
Formation at the coast between Aleklinta and Djupvik, and near Horns
Udde are shown in figs. 7 and 8 respectively.
1.2.2.2. Type-locality and type~section
Kopingsklint, section 1 (fig. 2).
1.2.2.3. Differential diagnosis
The Kopingsklint Formation may be distinguished from the underlying
Djupvik Formation by the predominance of fossiliferous limestones in the
former and of terrigenous clastics in the latter formation. It differs from the
overlying Bruddesta Formation by its high content of glauconite grains and
its relative paucity of fragments of fossils. Moreover, the Kopingsklint
Formation includes fossiliferous and glauconitic grainstones, which are absent
in the overlying Bruddesta Formation.
