Abstract: Objective Rock fracturing and its subsequent activations are the most basic tectonic deformation modes. However, the classical fracturing criteria (Coulomb-Mohr criterion, Griffith criterion, and Byerlee sliding-friction law) have different limitations in practical applications. Methods Based on th...

Abstract: Objective Hydraulic fracturing is a vital deformation and fracture mode in the whole crust-lithosphere range. The related structures are also critical ore-bearing structures of some hydrothermal deposits. Clarifying the main characteristics and identification marks of hydraulic fracturing ore-bearin...

Abstract: Objective Granitic magmas are genetically associated with magmatic-hydrothermal deposits and oil and gas reservoirs. The emplacement of granitic magmas into cooler rocks produced thermal anomaly and thermal stress, yet systematic studies on the spatial and temporal evolution of thermal stress still ...

Abstract: Objective The southwestern Guizhou region is a concentrated distribution area of Carlin-type gold deposits in China, with superior geological conditions for gold mineralization and enormous potential for mineral exploration. However, the shallow gold resources in the region have been largely exhaust...

Abstract: Objective The 509 Daobanxi deposit in the West Kunlun orogenic belt is a newly discovered large pegmatite-type lithium-polymetallic deposit in northwestern China. As a typical granite pegmatite lithium deposit in the region, the metallogenic characteristics and pegmatite evolution of the 509 Daobanx...

Abstract: Objective In the matter of material architecture, the diagenetic-metallogenic system may be classified into lithofacies of root-feeders (metallogenic material feeders), lithofacies of structural channel (migration of diagenetic-metallogenic material), lithofacies of closed-reservoir space (unloading...

Abstract: Objective The Qinghai–Tibet Plateau is rich in salt lake resources, known particularly for the concentration of elements such as boron and lithium, forming many distinctive resource-type salt lakes. Compared with ordinary salt lakes, a notable characteristic of resource-type salt lakes is the abunda...

Abstract: Objective The Haopinggou Ag-Au polymetallic deposit is a typical intermediate-sulfidation epithermal deposit in the Xiong'ershan ore concentration area. Ag-Pb-Zn mineralization mainly occurs in steeply dipping veins and breccia matrix. The relationship between large-scale Pb-Zn mineralization and wi...

Abstract: [ Objective ] Carbonatites, as magmatic-origin rocks, are crucial source rocks for uranium, rare earth, and other minerals. They are widely distributed in the Xiaoqinling region of Shaanxi, giving rise to numerous large to super-large carbonatite deposits of uranium, molybdenum, and rare earth, repr...
