[1845W. H. Fitton in Q. Jrnl. Geol. Soc. I. 189 If hereafter a change [from Lower Green Sand] be thought desirable, he [sc. the author] conceives that the new denomination should be taken from the Isle of Wight..; and if such a case should arise, he suggests the name of Vectine for the strata now called Lower Green Sand, from the ancient name of that island,—Insula Vectis of the Romans. ]1885A. J. Jukes-Browne in Geol. Mag. Decade III. ii. 298 The Lower Greensand can be studied so well in the Isle of Wight..that no name can be more appropriate than Vectian; and I regard the introduction of a new name as preferable to the adoption of the French names Aptien and Urgonien. 1922[see Selbornian a. 2]. 1961Palaeontology III. 502 The Vectian Province comprises the Isle of Wight and a small part of the Dorset mainland where a strip of Lower Greensand extends westwards from Swanage to Lulworth Cove. 1969Bennison & Wright Geol. Hist. Brit. Isles xiv. 323 In this Vectian Province the Lower Greensand becomes attenuated westwards at a more rapid rate than the Wealden (Neo⁓comian) Beds. |
