GrainSizeTools: a Python script for estimating the dynamically recrystallized grain size from grain sectional areas

Abstract

Paleopiezometry and paleowattometry studies, required to validate models of litho-spheric deformation, are increasingly common in structural geology. These studies require a numeric parameter to characterize and compare the dynamically recrystallized grain size of natural mylonites with those obtained in rocks deformed under controlled 5
