Staurolite twin -
Staurolite twin - Form of penetration twinning where two monoclinic crystals form interpenetrating twins at 90º, forming a cross, as depicted in the figure below. Named after the mineral Staurolite , which most frequently exhibits this form of twinning. (Staurolite crystals may also twin at angles other

Metamorphic evolution of the western Aston and Hospitalet domes
, staurolite and almandine garnet grew during periods of deformational quiescence. A phase of intense non -coaxial shearing, evident in rotated staurolite porphyroblasts, separates earlier staurolite growth from nucleation of andalusite. There is clear textural evidence that andalusite consumes staurolite (reaction 4) and
