Description

Rock type: Phyllite slate.
Age: Ordovician (approx. 460 million years).
Otta slate represents what was originally a clay/siltstone formation which during the Caledonian period was deformed and metamorphosed with the foundation of regular cleavage strata.
Good slate deposits occur in tight fold structures. Sheet thickness varies between 8 and 80mm.
In the lower part of a slate formation the phyllite contains large crystals of needle-like hornblend.
Pillarguri is exclusively quarried to the south of Ottadal, whilst H?gs?ter is quarried on the north side. In certain areas the slate can be found with a rusty surface.
This rust colour occurs in cleavage planes which have been exposed to erosion from water and to oxygen.
