What does the word allochthonous mean?

What is autochthonous Nappe?
An autochthonous nappe is a pseudo-, or false, nappe in the form of a bivergent or multivergent local structure, overthrust from the basement, but without noteworthy transport.
What is the difference between indigenous and autochthonous?
Autochthonous may specifically address the place of where the subject organism is originated and likewise the organism (or population) found in that place. Indigenous means native to some place where that organism (or population) does not necessarily have to be originated from.
What is recumbent fold?
A recumbent fold is one in which the axial plane is essentially horizontal, with the limit of variation of axial-planar dip, and the resulting limit of plunge, being 10° (Turner and Weiss, 1963; Fleuty, 1964). It is a sideways-closing neutral structure that is neither a synformal nor an antiformal fold.
What is drag fold?
Definition of drag fold : a minor geological fold produced in soft or thinly laminated beds lying between harder or more massive beds in the limbs of a major fold.
What is the difference between allochthonous and autochthonous?
allochthonous | autochthonous |. is that allochthonous is (geology) buried or found in a place remote from the site of formation while autochthonous is (geology) buried in place, especially of a fossil preserved in its life position without disturbance or disarticulation.
What is allochthon in geology?
Allochthon. In structural geology, an allochthon, or an allochthonous block, is a large block of rock which has been moved from its original site of formation, usually by low angle thrust faulting. An allochthon which is isolated from the rock that pushed it into position is called a klippe.
What are autochthonous sediments?
Autochthonous is a term that refers to sediments that are found in the same place where they were formed or in a location very close to its site of deposition. Therefore, autochthonous sediments or autochthonous rocks are found in their native place.
What is the difference between Klippe and allochthon?
A klippe is a solitary outcrop of the nappe in the middle of autochthonous material. An allochthon, or an allochthonous block, is a large block of rock which has been moved from its original site of formation, usually by low angle thrust faulting.
