In order to study mechano-chemical coupling in the process of dynamic deformation in gold ore deposit,deformation simulating experiments on rocks and mineral ores have been carried out at high temperature and high pressure.Observation under microscope and electron probe analysising on samples before and after tests showed that texture and structure of rocks and minerals havc been altered a lot which closely related to strength of deformation,and chemical compositions also correspondingly differed,giving out the evidence that mechano-chemical coupling occurred in deformation,and the dominating mechanism is pressure solution
