Short summary
We present mechanical models that use the attitude and opening angles of igneous sills to constrain stress axes, the stress ratio, and relative magma pressure during dilation. The models can be applied to any set of dilated structures, including dikes, sills, or veins. Comparison with paleostress analysis for coeval faults and deformation bands indicates that sills can be used to characterise the paleostress state in areas where other brittle deformation structures (e.g. faults) are not present.
