A roadcut in the Skavli residental area

Skavli, Borre, Horten, Vestfold, Norway

A road cut along Skavlisletta, Skavli residental area, Borre, Horten, Norway.
Ken Roger Olberg (at left) and Stig Larsen are examining this roadcut in Permian basaltic lava. In the Skalvli residental area), several mineralized amygdales were found in the 1980s during the construction of several roads and houses. Most of the finding-sites are now completely built over, under houses and gardens. There's still a few roadcuts in the area that may be studied.
Remnants of calcite-filled amydales may be seen as white areas in the basalt lava. I the lower part an area with pale-beige laumontite may also be seen.

An amygdale cavity in situ, Nordre Kleivan

Nordre Kleivan, Holmestrand, Vestfold, Norway

An amygdale cavity in situ, in a Permian basaltic lava, at Nordre Kleivan, Holmestrand, Norway. The cavity is about 18 cm across.
The following minerals may be seen in the photo: pale pinkish = laumontite, white cleavages = calcite, light greenish = prehnite. Aggregates of prehnite were found in the small cavities seen in the photo. Outside the cavity, black phenocryst of augite is seen in the basaltic lava rock.
Photo taken 13.02.2005.
The cavity has now disappeared due to the construction of a residental area at the site.

An amygdale cavity in situ, Solsikken

Solsikken, Botne, Holmestrand, Vestfold, Norway

During construction of a small road (now named Solsikken) for a residential area, a large roadcut was exposed in a Permian basaltic lava flow. A few irregular vesicular cavities which produced a few mineral specimens were viewed. One of these is seen as black hole in the rock wall in the photo. This road cut is now covered with a steel-wire netting for protection (it is now in a residential area with a lot of kids). The roadcut is partly covered with snow.

A part of the Tvillingbru collecting area as seen in 2005

Tvillingbru, Holmestrand, Vestfold, Norway

The upper part of the Tvillingbru collecting area as seen in 2005, Holmestrand, Norway. Minerals were found in the scree below the high cliff, mostly lower down than the part seen in the photo.
Note: Most of the scree has now been removed (2017) and inaccessible due to constructing of a escape-tunnel to the new railroad tunnel inside the cliff.

A quartz producing cavity along Hvittingfossveien

Hvittingfossveien, Kleivbrottet, Holmestrand, Vestfold, Norway

An irregular vesicule cavity in Permian basaltic lava was discovered in the late 1980s in a roadcut along Hvittingfossveien at Kleivbrottet, Holmestrand, Norway many years ago. Groups of small crystals of quartz as well as prehnite, chrysocolla etc were found in the cavity.
The photo is taken by Stig Larsen 10.04.2005, and showing me examining the cavity.
