Old mine for marble, a crystalline carbonate rock, in Kongsfjord.

The more important source of methane at depth (crystalline bedrock) is abiotic.

The only option we have in Finland is the crystalline bedrock,” says Äikäs.

A crystalline metamorphic rock characterised by dark-coloured layers (micas, amphiboles) alternating with light-coloured layers (quartz, feldspars).

You can descend into its crystal-clear rock pools for a swim or a soak, but only during low tide.

In area East, which is characterized only by one borehole at Siblingen, no such crystalline-rock domain of similarly favorable properties was observed.

The crystal rock form, commonly known as crack or freebase, is cocaine that has not been neutralized by an acid.

But we are also from the same folding, for the same crystallized rock raised and fractured in the drift of continents.

This is a layer of a hard, dark rock called dolerite, known locally as ‘whinstone’.

The crystal rock form, known as crack or freebase, has not been neutralized by an acid.

The word granite comes from granum, the Latin word for a grain, in reference to the grained and crystalline structure of this type of rock.

In Finland high-level radioactive waste is planned to be disposed of in a deep geological repository within a crystalline host rock.

Canada has two types of rock formations that are potentially suitable for a deep geological repository: crystalline and sedimentary.

In Finland high-level radioactive waste is planned to be disposed of in a deep geological repository within a crystalline host rock.

A L/ILW repository at a depth of 110 metres has also been in operation at Loviisa since 1998.
