Description: Rubers Law, from Spital, c. 9 km. south-west of Jedburgh, Roxburgh. Looking south. Volcanic neck plugged with basalt. Rubers Law is a typical feature of the igneous rocks in this part of the Borders where isolated volcanic necks form higher ground standing above the surrounding sedimentary rocks and lavas. It consists of a group of roughly circular plugs of Jedburgh-type basalt intruded into Carboniferous red sandstones and siltstones during Lower Carboniferous times. Jedburgh-type basalt is a variety of lava or intrusion with small phenocrysts of labradorite feldspar and a few small olivines. Augite (a pyroxene) is restricted to the groundmass.
