This invention relates to the field of mineral deposit exploration technology, specifically disclosing a method for determining the extension of magmatic hydrothermal deposits using fluid inclusions. The method involves collecting mineral samples containing fluid inclusions from the target deposit and its surrounding area using a systematic grid. Physicochemical parameters are obtained through petrography, microthermometry, and isotope analysis, and a spatial database is established. Multiple initial hydrothermal centers are identified. A multi-dimensional spatial constraint field is constructed, incorporating temperature-salinity-isotope gradients, mineralization depth, and magma-water mixing ratio. Using the initial centers as seed points, a neighborhood search is performed along the gradient synthesis direction. Sub-hydrothermal centers are generated and continuously grow when preset conditions are met, until an overlap threshold is reached, at which point iteration stops. All hydrothermal centers and growth paths are integrated to construct a spatial extension model. High-potential areas are screened using a target area evaluation index, and the extension direction and potential mineralization target areas are determined by combining the mineralization depth. This significantly improves the accuracy of concealed ore body prediction and the efficiency of mineral exploration.

This invention discloses an experimental apparatus and method for a similar model of a rock wall expansion. The apparatus includes a transparent experimental chamber, a layered gelatin system, a terrain simulation system, a dynamic injection system, a multimodal monitoring system, and a data acquisition and processing system. By independently adjusting the stiffness and density ratios of the upper and lower gelatin layers, combined with a detachable double-slope terrain mold, a systematic study of the coupled effects of multiple factors such as terrain, stiffness layering, density layering, and injection rate is achieved. The three-dimensional morphological evolution of the rock wall is simultaneously monitored using a multi-view high-speed camera, and the full-field displacement field, strain field, and principal stress direction during the rock wall expansion process are inverted in real time using digital image correlation technology. This reveals the control mechanism of stress gradient reversal caused by terrain on the lateral expansion and cessation of the rock wall. Furthermore, dimensionless analysis and boundary correction improve the similarity between the model and the natural prototype, providing a reliable experimental platform for volcanic eruption prediction and magma transport law research.
