Twinned calcite
WebAug 9, 1999 · A large set of strain data includes total shortening estimates based on balanced cross-sections, local strain axes orientations from the inversion of fault populations [Homberg, C., 1996. Unpublished PhD thesis, Université de Paris VI (France)], tectonic stylolites and micro-strains from twinning in sparry calcite. WebA classic heart shaped twinned Calcite from the Gillfoot Mine, Egremont. The Calcite is essentially colourless gemmy with very lustrous well formed faintly striated faces. Goethite inclusions create a deep brown filigree of dendritic growth on one edge.

Twinning in calcite There are four well-identified twin planes in calcite crystals, e = {018}, r = {104}, f = {012} and c = {001}, introduced either by deformation or as defects during crystal growth. e and r are the most common deformation twinning planes, depicted in Fig. 1. It should also be noted that the r-plane is the usual slip plane.
