| Abstract: | The paper focuses on the discussion of a shortcut method of hunting for gold in the shallow coverage, which has been used in the anomaly investigation of the pre-Cambrian metamorphic rock region and obtained a good result.The method includes four steps as follows: (1)to get more samples of fluvial heavy sand minerals in the surveyed area so to narrow the target area of hunting for gold ores, (2) to make tracks for the mineralized and altered zones and the weathered outcrops of orebodies or mineralized bodies by simply collecting the samples of manual heavy sand minerals,(3)to make a preliminary delineation of orebdies or mineralized orebodies by reconnaissance on the field surface and make an identification of the simple manual heavy sand minerals,(4)to make an uncover of anomaly areas by engineering and make an evaluation of the mineralized zones or gold orebodies. |
