A part of the small syenite pegmatite dike , in situ, at the Zircon prospect, Stokkøya, Langesundsfjorden.
FOV is about 13 cm.
The photo shows, black, crossections of andradite, var. melanite crystals (1,3 cm in diameter) frozen in white microcline . Small, thin ruler-shaped, yellowish crystals below the andradites are titanites, the variety which Brögger described as "eukolite-titanite". Some greyish masses of nepheline (partly altered to reddish natrolite) and smaller brownish zircons etc. may also be seen on the photo.

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.
