| Description: | Loch na Glas-choille, 4.8 km. south of Altnaharra, Sutherland. View of the Ben Klibreck escarpment of the Loch Choire migmatite complex. The high summit is Meall nan Con (961 m.) formed of an intimate mixture of metasedimentary pelitic schists modified by the injection of granitic material. There is an upward transition from unmigmatized metasedimentary rocks to migmatitic rocks. Smooth morainic drift mantles the lower slopes in foreground. It is thought that the migmatite is derived from the host schistose rock by a process of partial melting (anatexis) or by a process of segregation involving volatile components some of which may be from external sources, some of the larger granite masses may indeed be truly magmatic. |
