Cleavage strain in the Variscan Fold Belt, County Cork, Ireland, estimated from stretched arsenopyrite rosettes
Mary Ford,Colin C. Ferguson +1 more
TLDR
In this paper, a strain ellipse is estimated from each crystal rosette composed of three laths, assuming the original interlimb angles were all 60°, and this provides a lower bound to the area increase in the plane of cleavage.About:

Structural evolution of the Irish Variscides
TL;DR: In this paper, the effects of the Variscan orogeny on the Upper Palaeozoic succession are recognizable throughout central and southern Ireland, and the deformation can be zoned using structural styles and trends which illustrate a northward decrease in deformation intensity coupled with increasing control by pre-Variscan structures in the basement.

The formation and growth of pressure solution seams in clastic rocks: A field and analytical study
Filippo Nenna,Atilla Aydin +1 more
TL;DR: In this paper, the authors present new observations constraining the processes by which pressure solution seams (PSSs) initiate and grow in low porosity clastic rocks from southern Ireland.
Journal ArticleDOI
Asymmetric extensional structures and their implications for the generation of melanges
TL;DR: In this article, it is suggested that the melanges developed by the propagation of extensional displacement zones, analogous to shear bands, through sandstone beds, so progressively dismembering them.
Journal ArticleDOI
Interpretation of tectonically deformed fossils
TL;DR: Taxonomic information can be recovered from tectonically deformed fossils by analyzing the strain and then restoring the fossils to their original shapes as mentioned in this paper, using trilobites and graptolites as examples of two kinds of fossils.

Structural evolution of the Shimanto Belt accretionary complex in the area of the Gokase River, Kyushu, SW Japan
D. T. Needham,J. S. Mackenzie +1 more
TL;DR: The Shimanto Belt of SW Japan is an accretionary complex which developed between Late Cretaceous and Late Miocene and the deeper levels of this complex are exposed along the Gokase River of eastern Kyushu.

The use of balanced cross-sections in the calculation of orogenic contraction: A review
TL;DR: Balanced section calculations assume that the section has been deformed by a plane strain this paper, but in nature the area of the section may have decreased by 15-45%, but the assumption of plane strain always leads to a minimum estimate of shortening.

Structural evolution in the northern part of the Moine thrust belt, NW Scotland
D. Elliott,M. R. W. Johnson +1 more
TL;DR: In this article, four balanced cross sections, supported by longitudinal sections, structure contour maps, stratigraphic separation diagrams and hangingwall sequence diagrams are used to estimate the Moine thrust.
Journal ArticleDOI
The geometric effects of volume change during deformation processes
John G. Ramsay,Dennis S. Wood +1 more
TL;DR: In this article, deformation paths arising from tectonic deformation with progressive volume loss superposed on previously compacted material are computed, and these lead to predicted deformation fields which accord well with much of the data available on natural deformation field.
Journal ArticleDOI
Particulate flow of rock and the formation of cleavage
TL;DR: In this article, it was shown that the degree of coupling between intragranular deformation and particulate flow may change during the course of natural deformation, leading to a transition from controlled to dependent flow.
