Abstract:

 The method of structural superimposed halos is developed on the theory of prospecting blind ore by primary halos. Based on the facts that the formation of halos and orebodies in a hydrothermal deposit is rigorously controlled by tectonic structures and it shows a feature of superposition of multiforming period and multiforming stage, we developed the theory of superimposed primary halos, and solved the puzzles of appearance of abnormal bandings in the research of axial banding of primary halos for geochemists in decades, and proposed originally the new method of structural superimposed halos for blind ore prospecting. This paper introduced the features of structural superimposed halos and the main achievements in blind orebody prospecting, and four ideal models of superimposed frames for gold districts and five guidelines in the prognosis of blind orebodies, as well as the successful examples in gold regions.

Key words: new method of structural superimposed halo, prognosis of blind orebody, the deep of oredistrict, achievement in blind orebody prospecting
