| Abstract:The spatial combination patterns of ore-controlling structures and their structural and geomorphological expressions have been acquired through field investigation in more than three hundred hydrothermal deposits. Based on an analysis of these data on the principle of strain ellipsoid, the authors have proposed three types of structural models(respectively named A, K and X) for spatial localization of hydrothermal ore deposits which include deposits formed by hydrothermal fluids with different geneses and having the ability of transporting metallogenic materials to form ore deposits. This paper describes briefly characteristics of these three ore-controlling models and the methods for ascertaining the existence and the type of a model. It is indicated that the locations of relative concentration of stress (i. e., top or cross-beam)favorable for the accumulation of metallogenic substances exist in all three sorts of models. According to the extension of structural lines reflected by the structural topography in the field or through all indoor analysis of the combination forms and the convergent and divergent positions of the structural lines shown by satellite photographs, aerophotographs and geological maps. One Call determine rapidly whether there exists an ore-controlling structure in the studied area and what its type is, thus teadily delineating the section favorable for metallization．As demonstrated by some examples given in this paper, satisfactory results can be obtained in the application of these models to the ore prospecting and ore prediction in respect to the localization of ore deposits. In addition, the basic principles and the possibility of formulating these models are discussed by applying the theory of stress concentration in mechanics of materials and the method of stress analysis in structural geology. |
