    摘要:

    地质构造对岩溶发育控制作用是岩溶研究领域的重要内容。地质构造具有旋回性、继承性和新生性,这些构造特征如何有序、分级地控制岩溶系统形成和演化,以及在岩溶系统的初始启动、持续演化乃至消亡过程中发挥着怎样的作用尚需进一步揭示。笔者等在总结前人研究基础上,揭示在一期构造旋回中,阶段性区域性构造运动所产生的应力在积累到一定程度时超过碳酸盐岩强度就会发生岩石破裂,岩石破裂即代表一次应力的短暂释放,同时在表生作用和深部流体作用下沿着这些破碎带易发生岩溶作用,这便是岩溶作用初始启动构造;不同性质构造在一些特殊部位会形成拉张区域,有利于岩溶作用发育,岩溶进一步沿破碎带溶蚀扩大,则逐渐形成岩溶系统,但是随着下一阶段构造应力的持续积累,上一阶段破裂带则容易发生应力集中,继续叠加并改造上一阶段破裂带,造成上一阶段破碎带和岩溶系统的破坏,并形成新的岩溶系统。这便是递进变形过程,其本质是有限应变与增量应变的加成。然而新一轮造山运动又会打破上一轮构造格局并重建新的构造格架,同时对早期地貌和气候演变以及水系格局进行新的调整,岩溶地貌表现为继承性演化和新生地貌系统。这便是区域构造演化过程对岩溶系统演化的控制作用。

    Abstract:

    The control exerted by geological structures on karst development is a fundamental topic in karst research. Geological structures exhibit characteristics such as cyclicity, inheritance, and neogenesis. How these structural features orderly and hierarchically control the formation and evolution of karst systems, and their role in the initial onset, continuous evolution, and eventual demise of karst systems, remain to be further explored. On the basis of summarizing previous research, this paper reveals that during a single tectonic cycle, episodic regional tectonic movements generate stress that, upon exceeding the strength of carbonate rocks, leads to rock fracturing, which represents a brief release of accumulated stress.These rock fracture zones developed in the carbonate rockspromotes the initiation of karstification under epigenetic and deep fluidprocesses, referred to as inception structure, which marks the onset of structure controlled karst processes. In specific zones, structural configurations may generate extensional regimes that further facilitate karst development. As dissolution progresses along the fracture zones, a karst system gradually evolves. However, with continued stress accumulation in the subsequent tectonic phase, stress tends to concentrate along preexisting fractures, reactivating and modifying them, which may damage earlier karst systems and lead to the formation of new ones. This constitutes a progressive deformation process, essentially the cumulative result of finite strain and incremental strain. However, a new orogenic event can disrupt the preceding tectonic framework and establish a new structural regime, simultaneously reshaping preexisting landforms, climatic evolution, and drainage systems. This results in both inherited evolution and the development of a new karst geomorphic system, exemplifying the controlling influence of regional tectonic evolution on the formation and transformation of karst systems.
