| Abstract: | The main ore-control joint and fracture in Ertaizi gold deposit are determined and the principal stress direction is NNW-SSE according to rose diagram analysis.The ore-body occurs mainly as chimney.By classification of the ore-control fractures and their stages and matching the corresponding ore-control joints we analyze the mechanism of structure control on gold ore and the ore-forming regularity in Ertaizi gold deposit and the ore-searching directions are pointed out. |

| Keywords: | Ertaizi gold deposit fracture joint structure control on gold ore ore-forecast Shaanxi province |
