| 英文摘要: |
| This paper sums up the field and Lab data for Zhao-Ye metallogenic belt. Ore-controling factors are picked up and the conceptual model of gold deposits in the belt are established. Based on this optimum combination of ore-controling marks and analogue math model are determined; the total gold resource of the belt is estimated. Gold deposits are resulted from the assimilation of Jiaodong Group by granitic magma which mobilized gold within the assimilated part into granites, dykes and mineralized units. By calcuation, the total amount of gold in the assimilated part of Jiaodong Group is 24436t, the total gold in granites, 12950t, the total in mineralized units, 1641t (alteration zone), 5377t (mineralized quartz vein), 4825t (ore vein and deposit)among which 1230t industrial grde ore is cut by 3g/t. Therefore the belt is still of potentialality for futher exploration. |
