The recent deep prospecting results in the jiaojia area of Eastern Shandong Province indicate that the jiaojia ore field composed of several individual gold deposits as previously suggested is actually an ultra-large gold *** deposit covers an area of ～40 km2,and shows a structural control by the jiaojia fault and its secondary *** orebodies generally occur along the same mineralization-alteration belt,and the main orebodies intersect with each other or exhibit a parallel or overlapping *** deposit＇s reserves are estimated to be 1,200t of gold,being the first gold deposit of more than 1000t gold reserves in *** No.Ⅰ-1 orebody in the Shaling-deep Sizhuang ore blocks holds gold reserves greater than 350 t,or 29 percent of the total reserves,followed by the No.Ⅰ orebody in Matang-jiaojia ore blocks with exceeding 150t gold *** deposit mainly occurs in the footwall of the jiaojia fault,and presents zoned patterns in mineralization,alteration and *** strongly mineralized zones agree with strongly altered and tectonically fractured *** orebodies display strataform-like,veinlike or lenticular shapes,and generally show characteristics of pinching out and reappearing,branching and converging,expanding and *** orebodies commonly occur along positions where the fault strike changes and in gentle locations with dips changing from steep to *** main orebodies are parallel to the main plane of the orecontrolling fault,and tend to be gentle from the surface to the *** orebodies mainly plunge to the southwest,with plunge angle of 45°-606° Orebodies near the main plane of the ore-controlling fault have more gold resource than those away from main fault *** slant depth of orebodies is generally larger than the length along its strike direction; orebodies become thick and gold grades become low from the shallow area to the deep ***-forming fluids are H2O-CO2-NaCl±CH4 type with medium-tempe
