• Cryptocrystalline tool stones include flint and chert, which are fine-grained sedimentary materials; rhyolite and felsite, which are igneous flowstones; and obsidian, a form of natural glass created by igneous processes.
• Luing is cut by NE-SW aligned Siluro-Devonian felsite dykes and by numerous later NW-SE aligned basalt and microgabbro dykes which form a part of the ‘Mull Swarm’ which is of early Palaeogene age.
• The mass of the rock consists of a fine-grained matrix of felsic materials, particularly quartz, sodium and potassium feldspar, and may be termed a quartz felsite or quartz porphyry if the quartz phenocrysts are present.
• The lower parts of the slide scar are underlain by felsite sheets (which may have failed first) while the upper parts of the slide scar are underlain by highly jointed Paleozoic greenstone beds.
• These cooled to form very hard granophyre and felsite rocks – in fact two 'ring dykes' or the "outer" and "inner" rings.
• The conglomerates consist of grey feldspathic sand and well-rounded pebbles and cobbles of quartzite, granite, felsite, and quartz monzonite.
• This conglomerate is composed of a grey feldspathic sand matrix and well-rounded pebbles and cobbles of quartzite, granite, felsite, and quartz monzonite.
• In Seokjang-ri and in other riverine sites, stone tools were found with definite traces of Palaeolithic tradition, made of fine-grain rocks such as quartzite, porphyry, obsidian, chert, and felsite manifest Acheulian, Mousteroid, and Levalloisian characteristics.
• The Sax Dome contains an upper portion of cream coloured, aphanitic to fine quartz porphyry felsite with abnormal green glass filled fractures, and a lower unit of microsyenite with red and green glassy zenocrysts.
• Geologically, the two Dirrington Laws comprise Carboniferous volcanic felsite (riebeckite), and may be the remains of a laccolith, a type of volcanic intrusion into the surrounding sedimentary rocks of the Old Red Sandstone.
• Walls are constructed of a slightly hewn yellowish felsite stone with some fragments of khachkars imbedded into the exterior.
• In addition, shallow water calcarenites, conglomerates, coral debris, hemipelagic sediments, breccia, limestones, felsite, foraminiferal sand, pelagic ooze, reefal limestones and sediments have been recovered.
