Using AMS combined with mineral shape preferred orientation analysis to understand the emplacement fabrics of the Apiai gabbro-norite (Ribeira Belt, SE Brazil)
(SPRINGERNEW YORK, 2012)
The Apiai gabbro-norite is a massive fine-grained Neoproterozoic intrusion emplaced in a core of synformal structure that deforms low-grade marine metasedimentary rocks of the Ribeira Belt of south-eastern Brazil. The lack ...
Two- and three-dimensional shape fabric analysis by the intercept method in grey levels
(ELSEVIER SCIENCE BV, 2010)
The count intercept is a robust method for the numerical analysis of fabrics Launeau and Robin (1996). It counts the number of intersections between a set of parallel scan lines and a mineral phase, which must be identified ...
Shape Preferred Orientation (SPO) methodology for oriented hand specimens of rock and outcrops through digital image processing
(Universidad Nacional de Colombia Sede Medellin. Facultad de Minas. Escuela de Geociencias y Medio Ambiente, 2015-07)
The shape-preferred orientation (SPO) is a technique, which allows the study of the fabric of deformed rocks and understanding its dominant deformational style and partitioning. This work presents SPO results and methodological ...

Fabrics of pre- and syntectonic granite plutons and chronology of shear zones in the Eastern Borborema Province, NE Brazil
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
We used the fabrics of two granite plutons and U/Pb (SHRIMP) zircon ages to constrain the tectonic evolution of the E-trending Patos shear zone (Borborema Province, NE Brazil). The pre-tectonic Teixeira batholith consists ...
