STRESS FIELD OF CONTROLLING GOLD MINERALIZATION IN ZHAOYUAN-YEXIAN AREA IN SHANDONG PROVINCE

摘要:

Abstract:

Zhaoyuan and Yexian Coun ties in Shandong Province are the important gold production distriets in China.Structures of controlling the gold mineralization are mainlg faults.Based on the study of structures in the field the papar deals with the stress field contreographic prejection and conjugate fracturse deduction of the principal axis of stresses,the states of the stress fields before during and after the gold mineralization are deduced;the trajectory maps of principal stresses and some model patterns of s...
