Abstract:Tectonic generation is an important concept in geomechanics and tectonic geology. It refers to the sequence in which structural planes with different mechanical properties and orientations are formed during the same crustal movement. This occurs under the continuous action of the same period and dynamic action mode, or due to local changes in boundary conditions, which control the formation of structural features. Structural generation emphasizes the genetic relationship between structural features and serves as the basis for determining structural types and establishing structural systems.The structural generation relationship is common and distinct from the structural level. Different generation structures possess characteristics of time difference, derivation, absoluteness, and invisibility. Low- order structures are often distributed within the influence range of higher- order structures and are controlled by local stress fields. The study of ore- controlling structures should proceed from low order to high order. Starting with the investigation of ore- bearing structures,their mechanical properties and combination laws should be analyzed. This allows for the determination of ore- controlling structure types and the summarization of ore- controlling laws. Ore- prospecting predictions should follow a high- order to low- order approach. Based on the ore- controlling structure type and the control law of structure generation, the possible position and direction of low- order ore- bearing structures are analyzed, enabling ore- prospecting prediction. Through the structure generation analysis of ore- controlling structures, the Zoujiashan uranium deposit is considered to be controlled not by the NE- trending Zoujiashan- Shidong fault but by the NEE- trending hidden structural belt with a medium- low dip angle, dipping to NNW. The prospecting direction is along the SWW direction of the existing ore belt, and the deep part has a medium dip.In the Changjiang uranium ore field, uranium mineralization is not controlled by the Mianhuakeng fault and Youdongfault but by the NNW- trending structural belt with a steep dip angle. The shallow secondary fault is an ore- bearing (or ore- storing) structure, and the main structural belt,which merged from them and extended to the deep, plays the role of guiding mineralization and transporting ore- forming hydrothermal solutions (deposit distribution). The ore- prospecting direction is the extension and deepening part along the NNW- trending ore- bearing structure and the deep part of the surface mineral- free zone.When analyzing structural generation, it is essential to pay special attention to the genetic relationship of structural features along with structural periods. It is crucial to distinguish between structures formed before, during, and after mineralization. Within a specific ore field deposit or mineralization zone, the relationship between ore- guiding structures, ore- transporting (ore- matching) structures, and ore- storing (ore- bearing) structures (i.e., the relationship between ore- controlling structures and ore- bearing structures) should be objectively analyzed.This analysis allows for the determination of an ore- controlling structural type, the construction of a structural ore- controlling model, and ultimatelyguides the practice of ore- prospecting and prediction.
