<p>The oceanic transform fault (OTF) is one of the three types of plate boundaries. It provides an important channel for the exchange of material and energy within the Earth’s interior, which is significant for understanding global plate tectonics. In recent years, substantial progress has been made in the study of OTFs, including their morphology, crustal accretion mode, stress and strain state, brittle-ductile deformation structures, and segmentation and symmetry of seismicity. The combined effects of magmatism and tectonism shape the morphology and structure of OTF: the spreading rate and the age offsets reflect the thermal structure of the OTF, and thus affect the intensity of magmatism; meanwhile, the stress within the lithosphere and plate motion control the tectonic features and formation of faults. Three-dimensional dynamic models have demonstrated that increased magmatism at mid-ocean ridges destabilizes the fault, thereby facilitating the dynamic evolution of the OTF. Moreover, the maximum depth of earthquakes on OTF is controlled by the thermal structure of the lithosphere, which is crucial for characterizing the fictional properties of faults and understanding their seismic behaviors. Based on recent comprehensive research findings, this paper reviews the tectonic features, three-dimensional morphological structure, and lithospheric thermal structure of OTF, and discusses important scientific issues, including the magmatic-tectonic co-evolution and geodynamic mechanisms of OTF. Future research will combine high-resolution observations and theoretical simulations to further elucidate the processes and mechanisms of OTF, providing important advances to global plate tectonic theory.</p>
