摘要
Massive sulphide ore from Hongtoushan of Liaoning Province comprise pyrite, pyrrhotite, chalcopyrite, sphalerite, quartz and silicate minerals.During the experiment, sulphides were reactivated intensely, and the main products are veinlets and microcrystallites, with the former occurring mostly in fragments of pyrite porphyroclasts. Present experimental results indicate that the sulphides can be intensely remobilized in both mechanical and chemical ways in accompany with deformation and metamorphism, and that remobilization will be enhanced at higher temperatures.
