The final process is the examination by the independent Harris Tweed Authority which visits the mills weekly, before application of their Orb Mark trademark which is ironed on to the fabric as a seal of authenticity. In 2012 the weavers and mills of the Harris Tweed industry produced one million metres of Harris Tweed, compared to 450,000 metres in 2009, which was the highest production figures in 17
Donegal batholith Dalradian and the granodiorite. These early phases were followed by the emplacement of a large volume of porphyritic monzogranites at a time when the granodiorite and tonalite had cooled sufficiently to fracture. This pluton lies at the southwestern end of the Main Donegal granite. Three distinct types of granite are recognised, an outer biotite monzogranite inside which there is a body of biotite-muscovite monzogranite and in the centre is an aplitic biotite-muscovite microgranite. The intrusion is interpreted to have the form of a laccolith. The main part of the pluton shows only weak evidence of deformation. Studies of the anisotropy
