Origin: A borrowing from French. Etymon: French montien.

Etymology: < French montien (G. J. G. Dewalque Prodrome d'une descr. géol. de la Belgique (1868) x. 185) < Mont- , Mons , post-classical Latin form (compare mount n.¹) corresponding to French Mons , Dutch Bergen , the name of a town in south-west Belgium + -ien -ian suffix.

Geology.

Of, relating to, or designating a stratigraphic stage in western Europe represented by limestone beds in the region of Mons in Belgium, now usually regarded as partly equivalent to the Danian and placed at the bottom of the Tertiary, below the Thanetian or (in Belgium) the Landenian, but sometimes differentiated from and placed above the Danian. Also as n. (usually with the).The Montian was formerly sometimes regarded as the last stage of the Cretaceous.

1882 A. Geikie Text-bk. Geol. 848 The most ancient Tertiary deposit of the west of Europe appears to be the limestone of Mons (Système Montien.).]

1885 Amer. Naturalist 19 1094 The Eocene is divided into Montian, Landenian, Ypresian and Parisian.

1896 J. W. Judd Student's Lyell xv. 220 Paleocene Beds (‘Montian’).—In the coarse limestone of Mons in Belgium and in the Marls of Meudon in the Paris basin we have strata which are perhaps older than any in the British Islands.

1914 J. Park Text-bk. Geol. xxx. 416 The concretionary limestone of the upper division, representing the Montian sub-stage of the Cretaceous system, has yielded..the very characteristic Danian cephalopod, Nautilus danicus.

1921 Geol. Mag. 58 146 The Montian (Calcaire pisolitique) is now only found in a few isolated patches and seems to have been deposited in certain areas rather than over the whole Paris region.

1955 G. G. Woodford tr. M. Gignoux Stratigr. Geol. ix. 473 Far from being localized in narrow grooves, the Montian sea was widespread in a large gulf.
