| Abstract: | Songjiagou gold deposit occurrs in conglomerates of Pre-cretaceous Laiyang group, which is altered conglomerate type gold deposit controlled by concerntrating belt of faults and cracks. This gold deposit is a hidden one, and has the same characteristics with Pengjiakuang altered rocks type gold deposit occurring at the edge of basin. The major control factors of the deposit are faults, and the ore-forming age is late Yanshan period of Mesozoic. |

| Keywords: | Altered conglomerate type gold deposit geological condition of ore-forming fault controlling deposit Muping in Shandong province |
