Allochthone

In the northern Taconic Range of centralwestern Vermont an allochthone has been postulated.

The existence of an allochthone resting on an autochthone implies the existence of an overriding surface.

In addition, modern workers generally concur that, immediately surrounding the controversial Taconic allochthone, there is a nearly continuous belt of Middle-Ordovician gray to black argillite.

The idea was no sooner mooted, than we were reliably informed that we would have to play down considerably the Muslim component, sheltering behind a broader allochthone scout concept.

Immigration and differential fertility behaviour of immigrants may lead to a substantial demographic substitution of the authochthone by the allochthone population in specific urban areas or regions.

However, who is "allochthone" and who is "'autochthone" is a matter of absolutely unclear classification, and the term allochthone soon started to be used mainly for the Moroccans and the Turkish.

The latter again consists of two groups: the autochthone (those that live permanently in the ice all their lives) and the allochthone (those that are associated with ice only for part of their lives, or for part of the year only).
