Abstract: Although the development of theories and methods for positioning prognosis of concealed gold deposits is difficult,they are being widely explored by geoscientists in the world.The paper introduces a kind of new idea and method:“texture model of ore deposits” which is theoretically based on a great deal of geologic prospecting experience of gold deposits,chiefly of hydrothermal genesis,under different kinds of geologic background.As a combined concept of dynamic metallogenic processes and static prospection mode,the model consists of three basic parts:the rank of ore-control structures,the time sequence of ore-control structures,the spatial allocation pattern of ore bodies.This can be regarded as the practical description of knowledge on the 3Dt framework of ore deposits,the emplacing geometrical regularities of ore bodies in 3D texture framework of ore deposits,the distribution pattern of element geochemical fields,ect.The main goal of the model is to carry out the positioning prognosis of concealed ore deposits more effectively and to establish a kind of orderly and operational predicting procedure both in theory and practice.The connotation,significance,scope of application and four main points of the model have been discussed.The key aspect of “positioning prognosis” of concealed gold ore bodies is to propose the most favorable metallogenic and exiting structural positions.It is necessary to properly use all kinds of predicting methods,but the main method should be the analysis of ore-control structures.The ideas of texture model of ore deposits can be applied in other kinds of ore deposits and regional metallogenic prognosis.Taking Tuanjiegou gold deposit as an example,the paper describes the basic thought and the operating procedure of establishing texture model of gold ore deposit.
