  abstract = {{T}he present study provides a quantitative way to analyze and interpolate strainfields from ductile fabric field measurements using geostatistics. {B}ased on variogram analysis and kriging interpolations, the developed methodology allows computing automatic cleavage and lineation trajectory maps at different scales from a same field structural dataset. {F}or the example provided by the hot {V}ariscan crust of the {P}yrenees, the analysis of cleavage/stretching lineations orientation and kinematic data document pure shear conditions recorded during convergence. {S}train was vertically partitioned between an upper crust submitted to homogeneous thickening responding to {N}-{S} (orogen-normal) shortening and a hot and partially molten mid-lower crust affected by horizontal longitudinal (orogen-parallel) flow. {T}he emplacement of plutons and gneiss domes generated heterogeneities in the upper crust and induced strain localization into steep anastomosed transpressional shear zones flanking those structures. {T}he results show that geostatistics applied to structural geology are powerful tools for retrieving tectonic regimes of large orogenic segments by identifying and quantifying perturbations in the strainfields induced by protracted and potentially complex tectonic histories. {T}he variogram analysis also gives first order clues to evaluate whether the considered structural domains underwent single continuous ductile or polyphased brittle-ductile deformation.},
