Folds jpb, 2020. FOLDS . The term . fold. is used when one or stacks of originally flat and planar surfaces such as sedimentary beds become bent or curved as a result of plastic (i.e. permanent) and ductile deformation. Folds in rocks vary in size from microscopic crinkles to mountain-size folds.They occur singly as isolated folds and in extensive

Differential stress transmission in the horizontal plane, through rigid materials bordering incompetent beds, gave rise to en chelon folds and The term 'en echelon' refers to closely-spaced, parallel or subparallel, overlapping or step-like minor structural features in rock (faults, tension fractures), which lie oblique to the overall structural trend.Conjugate deformation structures are related in deformational origin. Extensional stresses create fractures that can infill with calcite. When rocks deform in a brittle manner, the The Nankalayuergun fold zone in the North Tarim Basin, NW China, provides an exceptional opportunity for documenting the structural characteristics and evolution of en echelon folds along transpressional fault zone. However, the genetic mechanism of these en echelon detachment folds remains debatable due to poor understanding of the deep structure. En echelon veins. Jump to navigation Jump to search.

Obtains the quantitative relations among en echelon angles of en echelon folds, ratios of boundary stresses and en echelon pitches of shear zone under an action of general boundary forces (tension shear, pure shear or compression shear).

The data show a consistent strain pattern, from the Upper Triassic through the Lower Jurassic, of northeast shortening and northwest extension, and suggest that en echelon folds formed along an east-trending sinistral shear couple.
