Isoclinal Fold

Isoclinal Fold

 

or isocline, a fold in sedimentary rocks where the axial surface and limbs slope in the same direction and at approximately the same angle. Isoclinal folds are formed under conditions of intensive lateral compression or with slipping brought about by the force of gravity.

1992), the eastern part of the Strazek Moldanubicum was deformed in the lower crust, which led to the formation of isoclinal fold texture.
These drill holes, combined with Stage I drilling and geophysical inversion modelling, suggested that a large body of magnetite gneiss occurs in the area, possibly as an overturned isoclinal fold, with a south southeast dipping axial plane.
Various forms of minor folds that are found associated with the rocks of the Imphal Valley are Coffer (Box) fold, Sharp (Angular) fold, Isoclinal fold, Harmonic and Disharmonic fold.
A single traverse of eight drill holes at Murphy South, combined with Stage I drilling and geophysical inversion modelling, suggests that a large body of magnetite gneiss occurs in this area as a large overturned isoclinal fold, with a south southeast dipping axial plane.
The structure of the 132 North deposit is dominated by a small north-plunging parasitic isoclinal fold which lies on the steeply dipping western limb of the 132 Anticline, immediately north of the Widgiemooltha Dome (Fig.
Recent trenching and ground electromagnetic surveys indicate that the host Willett horizon also occurs some 2600 feet to the north on the opposite limb of an isoclinal fold.
Strata in the Fredericton trough dip steeply, typically within 15-20[degrees] of vertical and numerous reversals of facing indicators demonstrate significant crustal shortening through small-scale upright isoclinal folds.
The thickness of individual units or "beds" is quite variable and progressive changes in unit thickness within the mine suggest the presence of one or more isoclinal folds.
Since the Bonanza Ledge is interpreted as a replacement body that is replacing the fold noses of tight isoclinal folds that in the Bonanza Ledge area are flat lying rod shaped bodies, it is believed that these intersections represent true thickness or as close as true thickness can be estimated in this style of mineralization.
