title = "Combined quantification of anisotropy and inhomogeneity of magmatic rock fabrics - An outcrop scale analysis recorded in high resolution",
abstract = "Magmatic mineral distribution patterns in a syntectonic syenite pluton have been recorded at high resolution over several square metres on quarried faces. The anisotropy and inhomogeneity of K-feldspar and mafic mineral distribution patterns have been quantified using two methods originally based on fractal geometry. (1) Map-counting, based on box-counting, illustrates an inhomogeneity on the decimetre to metre scale and highlights diffuse structures that can be related to mafic schlieren or felsic dykes that are not visible on the rock surface. (2) We have developed a mapping of rock fabric anisotropy (MORFA) method that leads to the detection of further magmatic structures that are not visible in the field. With MORFA a magmatic lineation and its variation over large areas is determined, as well as fabrics on the decimetre to 1 m scales, which possibly represent flow or fracture structures in the crystallising magma.",

note = "Funding Information: Many thanks are due to Tom Blenkinsop and an anonymous reviewer for their reviews which highly improved the paper. Financial support by the Leonhard-Lorenz Foundation (grant 629/04 ) for MP, by FAPERGS (Rio Grande do Sul State Research Foundation) and CNPq (Brazilian Research Council) for MFB and by the German Academic Exchange Service (DAAD) for JHK are gratefully acknowledged. Many thanks are due to Chris Wilson for many constructive comments on the manuscript and to Axel Gerik and Christian Schneider who programmed algorithms for automating the map-counting and MORFA method. Thanks are also due to Kurt Doppler for construction of a special tripod for field photographs, to Vladimir Ruttner for preparation of the thin sections, and to Monika Nie{\ss}ing for stitching together the field photographs.
