- an elongated fold in sedimentary rock that resembles an arch in which rock layers slope downwards in opposite directions from the central axis (the apex of the fold)
A subsurface fold structure in which beds dip in opposite directions from a common ridge or axis A fold that is concave downwards See illustration in fold
A geological term describing a fold in the earth's surface with strata sloping downward on both sides from a common crest Anticlines frequently have surface manifestations like hills, knobs, and ridges At least 80 percent of the world's oil and gas has been found in anticlines
fold in the rocks of the Earth's crust in which the layers or beds bulge upwards to form an arch The opposite of an anticline is a syncline
An arch of stratified rock in which the layers bend downward in opposite directions from the crest
(a) [landform] A unit of folded strata that is convex upward and whose core contains the stratigraphically oldest rocks, and occurs at the earth's surface In a single anticline, beds forming the opposing limbs of the fold dip away from its axial plane Compare - monocline, syncline, fold SW & HP (b) [structural geology] A fold, at any depth, generally convex upward whose core contains the stratigraphically older rocks GG
An upfold or arch of stratified rock in which the beds or layers bend downward in opposite directions form the crest or axis of the fold
A fold in layered rocks originating below the surface in the form of an elongated dome Anticlines make excellent drilling prospects since any oil in the deposit will naturally rise to the highest point of the structure because oil has a lower specific gravity than water
A fold that is convex upward or had such an attitude at some stage of development A geological upfold opening downward
fold, generally convex upward, whose core contains the stratigraphically older rocks
A upward-curving (convex) fold in rock that resembles an arch The central part contains the oldest section of rock syncline-->
A fold of rock, generally convex upward, whose core contains the stratigraphically older rocks
