Evaluation of computational methods of paleostress analysis using fault-striation data [PDF]

open access: yes, 1991
Over the past 12 years, many different computational methods or variations of existing methods have been proposed for determining paleostress tensors from fault populations and their slip directions.

Mechanical analysis of fault slip data: Implications for paleostress analysis

Journal of Structural Geology, 2011
Abstract Stress inversions are a useful and popular tool for structural geologist and seismologist alike. These methods were first introduced by Wallace (1951) and Bott (1959) and subsequent studies continue to be based on their assumptions: the remote stress tensor is spatially uniform for the rock mass containing the faults and temporally ...

Brittle tectonics and paleostress analysis of the Strzegom – Sobótka granite massif

2023
The Strzegom – Sobótka Massif has been subject of brittle tectonics studies for more than a century. Due to an ongoing extensive mining activity, numerous good exposures occur in a relatively small area, especially in the western part of the massif.

Finite-element modelling of Tertiary paleostress fields in the eastern part of the Tajo Basin (central Spain) [PDF]

open access: yesTectonophysics, 1998
Three subsequent Tertiary paleostress fields that are deduced from fault-slip data for the eastern part of the Tajo Basin are analyzed by finite-element studies. The modelling results show that maximum horizontal stresses (SHmax) are mainly controlled by

Paleostress analysis from sheared dike sets

Geological Society of America Bulletin, 1989
It is a frequently reported feature of basement terranes that dikes intruded late in the deformation sequence become sheared parallel to the dike margins. It is proposed that such sets of sheets with internal fabrics produced by this shearing along their walls are structures which are dynamically analogous to reactivated faults.

Brittle tectonic evolution and paleostress field reconstruction in the southwestern part of the Fennoscandian Shield, Forsmark, Sweden

open access: yesTectonics, 2011
Six hundred fault slip data have provided robust paleostress fields within an approximately 35 km3 volume of Paleoproterozoic (1.9 Ga) rocks in the southwestern Fennoscandian Shield, Forsmark, Sweden.

Paleostress analysis of heterogeneous fault-slip data: The Gauss method

Journal of Structural Geology, 2007
We describe the Gauss method for reconstructing paleostress tensors from heterogeneous fault-slip data. We define compatibility measure and compatibility function, which verify the compatibility of a given stress tensor with observed fault-slip data. In order to constrain inversion results to mechanically acceptable solutions, we additionally consider ...

Forty years of paleostress analysis: has it attained maturity?

Journal of Structural Geology, 2019
Abstract Powerful methods of paleostress analysis from fault-slip data have been used since the 1970's, and have demonstrated their capacity for reconstructing stress fields with tectonic significance. However, in some cases, these methods have been applied to samples that do not fulfill basic requirements, or developed on the basis of unsound ...

Neogene evolution of the Sorbas basin (SE Spain) determined by paleostress analysis

Tectonophysics, 1996
Abstract The Neogene subsidence history of the Sorbas basin, situated in the Internal Zone of the Betic Cordilleras of southeastern Spain, is strongly controlled by strike-slip deformation. The sedimentary sequence of the basin offers a good control on the timing of separate phases of fault activation.

Cretaceous paleostress analysis of the Adriatic Carbonate Platform (AdCP)

2004
The Adriatic belt of the AdCP, or what is to-day the Adriatic zone of the External Dinarides, is largely built up of Upper Cretaceous platform limestones. They have variable thicknesses in different structural settings, and, in adition to that, a rather pronounced facies variability.
