Force Garth Quarry was opened in 1932 and is a key provider of building materials throughout Northern England. Dolerite rock (known locally as whinstone) is quarried from the site, which produces between 250,000 to 300,000 tonnes a year. The quarry is estimated to contain about 18 million tonnes of reserves. In 2012, Cemex UK Operations Limited (currently working the quarry) applied for permission from Durham County Council to expand it and extract a further 5.2 million tonnes over the next 15 years.

“Ilvaite, a rare calcium-iron silicate, is present in the dolerite-pegmatite facies of the Whin Sill at Force Garth Quarry near High Force in Teesdale, Co. Durham. Ilvaite forms part of an association of opaque minerals that includes ilmenite, altered titanomagnetite, titanite and minor sulphides, notably pyrrhotite, chalcopyrite and sphalerite that is characteristic of ilvaite in mafic igneous rocks. Other than the presence of ilvaite and trace amounts of molybdenite there is nothing unusual about the sampled dolerite-pegmatite suggesting that ilvaite may be present in dolerite-pegmatites elsewhere in the Whin Sill. This is the first authenticated occurrence of ilvaite in the British Isles.

The opaque mineralogy of pink aplite from the Whin Sill at Ratcheugh Quarry near Alnwick comprises ilmenite, titanite and pyrite with minor amounts of pyrrhotite, chalcopyrite, iron-rich sphalerite and galena. Much of the sulphide assemblage and associated baryte is later than the crystallisation of the aplite.

In addition, there appears to be nothing petrographically special about the Force Garth dolerite-pegmatite other than the recognition of ilvaite in the mineral assemblage and the presence of altered olivine in the dolerite wall rocks. It is possible that ilvaite is more widespread in northern England than this single occurrence indicates.”
