Field relations between dikes and joints: Emplacement processes and paleostress analysis
Journal of Geophysical Research: Solid Earth, 1986Sedimentary rocks intruded by Tertiary mafic dikes on the Colorado Plateau typically display systematic dike‐parallel joints. These closely spaced joints occur only near dikes, their spacing commonly increasing with distance from the dike contacts. Igneous breccias along some of these joints indicate that the joints are not younger than the dikes and ...

PALEOSTRESS ANALYSIS OF KAROO SUPERGROUP OF THE TSHIPISE-PAFURI BASIN, SOUTH AFRICA
South African Journal of Geology, 2015The Tshipise-Pafuri basin is located in the Limpopo Province, north-eastern South Africa. This paper presents the first paleostress-analysis results from fault-slip data on the sedimentary rocks of Karoo Supergroup of late Palaeozoic to early Mesozoic in Tshipise-Pafuri basin.

Whereas most of the stress inversion methods using fault slip data only minimize the angle between the measured striation and a computed shear stress to find the best fitting reduced stress tensor, Angelier (1990) proposed an alternative method named INVD that also takes into account the relative shear stress magnitude which allows the fault to move.

Romsa: a basic program for paleostress analysis using fault-striation data
Computers & Geosciences, 1988ROMSA allows the directions of principal stresses (σ1 > σ2 > σ3) to be estimated from data consisting of orientations of fault planes and their associated slip directions. The calculations make use of the well-known compressional and dilatational quadrantal arrangement of potential σ1 and σ3 directions.

Determination of 3D Paleostress Systems: An Additional Technique for Basin Analysis: ABSTRACT
AAPG Bulletin, 1988The present structure of the western Mediterranean has been largely determined by several phases of rifting and oceanic spreading which began during the Oligocene. The main rifting event took place during the middle Oligocene-earliest Miocene. This is indicated by structural, stratigraphic, metamorphic, and volcanic data.

Fault-slip analysis and their constraints on paleostress state evolution
2007Fault-Slip Analysis and their Constraints on Paleostress State Evolution Judith Sippel and Magdalena Scheck-Wenderoth GeoForschungsZentrum Potsdam, Sect. 4.3: Organic geochemistry, Telegrafenberg C427, D-14473 Potsdam, Germany We investigate different methods to derive the paleostress fields which controlled the evolution of sedimentary basins ...
