英文摘要	The Quaternary glaciation of Gurla Mandhata (Naimona'nyi), an impressive, isolated dome-shaped massif situated in a remote region of southern Tibet, was examined using glacial geomorphic methods and dated using Be-10 terrestrial cosmogenic nuclides. The oldest moraines, representing an expanded ice cap that stretched similar to 5 km into the foreland of the Curia Mandhata massif, likely formed during marine isotope stage (MIS) 10 or an earlier glacial cycle. Another glacial expansion of coalescing piedmont type occurred during the early part of the last glacial cycle or the penultimate glacial cycle, after which glaciers became restricted to entrenched valley types. Impressive latero-frontal moraines at the mouths of most valleys date to the early part of the last glacial cycle and MIS 3. A succession of six sets of moraines within the valleys and up to the contemporary glaciers show that glaciers advanced during the Lateglacial, Early Holocene, Neoglacial and possibly Little Ice Age. The change of style of glaciation throughout the latter part of the Quaternary, from expanded ice caps to deeply entrenched valley glaciers, might reflect: (1) climatic controls with reduced moisture supply to the region over time; and/or (2) tectonic controls reflecting increase basin subsidence due to detachment faulting and enhanced valley incision.
