剪切带斑晶塑性大变形计算机模拟太行山 - Plastic strain first starts from ambient of the porphyroblast , and then develops to rims of porphyroblast and gradually transfers to the centers of porphyroblasts . the brittle remains in the central parts of porphyroblasts come to be decreased through the plastic deformation development , which is accordance with the banding of intensity in many mylonitization zones on wild occurrences and observation in the fabrics of mylonitization rocks under microscope
长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。
