1F shape structure; a new exploration model for veined gold silver deposits


, : 1F shape structure; a new exploration model for veined gold silver deposits. Dizhi yu Kantan = Geology and Prospecting 29(10): 5-12

"Phi " shaped structure is a kind of tectonic style characterized by ring structure superimposed by linear structure which cut ring structure. For types of "Phi " shaped structure have been found: geophysical, geochemical, remote sensing and geological. Ring structures control the dimension of mineral deposits and mineral, linear structures control the distribution of the deposits, ore bodies and anomalous zone. "Phi " shaped structure is a tectonic model related with veined precious metal deposits, which was indetified and summarized by using multi-information exploration and prediction method during the exploration and prediction of gold and silver deposits in the northeastern of Shanxi Province, China. Application of the model to the gold (silver) deposits in the northern of China has proven its effectiveness. Therefore, the model can serve as an important exploration model for gold and silver deposits. This paper introduces the concept, types and scales of the "Phi " shaped structure, the ways of the model construction and its application to exploration and assessment.
