1895Mineral. Mag. XI. 115 It [sc. sölvsbergite] is a true dyke-rock (‘hypabyssal’ rock). 1896Science Progress IV. 476 Brögger has insisted on the necessity of a division intermediate between the plutonic and the volcanic, which he terms ‘hypabyssal’. 1896Q. Jrnl. Geol. Soc. LII. 613 The laccolitic rocks..would seem to belong to what Prof. Brögger calls hypabyssal. 1926G. W. Tyrrell Princ. Petrol. vi. 106 The hypabyssal group includes the rocks of dykes, sills, and small laccoliths, etc., which occupy an intermediate position in the crust between the deepseated plutonic bodies, and the surficial lava flows. 1951Turner & Verhoogen Ign. & Metamorphic Petrol. iii. 51 Some writers recognize an intermediate (hypabyssal) class to include rocks that have crystallized at moderate depth. 1969Bennison & Wright Geol. Hist. Brit. Isles x. 251 The Great Whin Sill is the largest hypabyssal intrusion in Britain. |
