黄铁矿的变形机制,是一个长期争论的问题。许多形变的硫化物矿体都呈现出黄铁矿的碎裂结构,在有些部位也见到了拉长的黄铁矿构造现象。尽管以往有关黄铁矿的形变实验都是以脆性域的变形为主,但近来在400—700℃的高温条件下的实验研究即表明,黄铁矿能通过位错作用而变形(Cox等,1981)。对早期实验的重新估价也同样表明位错滑移能在黄铁矿中起作用(Graf等,1981)。Atrinson(1972)曾经进行过
Pyrite deformation mechanism is a long-standing issue of controversy. Many of the deformed sulfide ore bodies present fractured pyrite structures, with elongated pyrite structures also seen in some areas. Although the previous deformation experiments on pyrite are mainly based on the deformation of brittle domains, recent experimental studies at high temperatures of 400-700 ° C show that pyrite can deform by dislocation (Cox et al. 1981). The reevaluation of earlier experiments also showed that dislocation slip can play a role in pyrite (Graf et al., 1981). Atrinson (1972) has been
