This paper presents new data on various types of pegmatites from the Larsemann Hills oasis (Princess Elizabeth Land, East Antarctica), collected during the 70th Russian Antarctic Expedition in 2024-2025. As a result of comprehensive geological and geophysical investigations, all pegmatite occurrences in the area belonging to different stages of the Pan-African orogeny have been described, analyzed, and systematically classified in a unified context for the first time. In addition to previously known pegmatites associated with deformation stages D2-3, D4, and post-D4, a further subdivision is proposed based on mineralogical-geochemical characteristics and the content of natural radionuclides. These include borosilicate D2-3 pegmatites, rare-metal D4 pegmatites, muscovite-bearing post-D4 pegmatites, as well as two newly identified types not previously described in the region: K-feldspar D4' pegmatites and miarolitic rare-metal post-D4' pegmatites, which differ in morphology, mineralogy, and geochemical features. Special attention is given to the structural-tectonic control of pegmatite bodies, their geological setting, zoning patterns, and the results of gamma spectrometric and magnetic surveys. Pegmatitic formations containing rare typomorphic minerals – such as tourmaline, boralsilite, grandidierite, and chrysoberyl – are also examined. The results indicate a significant diversity of pegmatite formation conditions, help refine the PT parameters and timing of the initial and final stages of the Pan-African metamorphic event, and confirm the genetic link between pegmatite development and D2-D4 deformation stages. These findings contribute to the reconstruction of Early Paleozoic pegmatite-forming stages during anatectic processes in the geodynamic evolution of East Antarctica and Gondwana.
