(1) Age, metamorphic process and tectonic implications of the granulitized basic dike swarm in the Vestfold Hills in East Antarctica: The study revealed that mafic dykes have experienced A diagram showing the deep background and process of the Late Cretaceous diagenesis and metallogenesis in the western part of South China2013 ANNUAL REPORT 10 inhomogeneous granulitization, which implies that the Vestfold landmass has been involved into the Rener collision-orogenic process resulting in the convergence of the India craton and East Antarctica, which is similar to Archean landmasses such as the Napier complex, Rauier Group and Lambert terrane. This is of great significance for reconstructing tectonic evolution of the eastern Antarctic continent during the Grenville Stage and reconstructing the supercontinent.
(2) Formation mechanisms of large-scale landslides in active structural belts: The study argued that convergence areas of regional active faults are structural positions prone to large and even huge landslides, and proposed that a seismic landslide usually witnesses five stages in its formation and evolution. A model was then built for the formation of geological hazards, which can serve as an important guide for early recognition of geological hazards.

 (3) Oil-gas-reduction metallogenesis of the Wulagen lead-zinc deposit in Xinjiang: A metallogenic model was proposed for this lead-zinc deposit: the ore deposit was formed when ore-forming materials such as Pb and Zn precipitated and cumulated in oil-gas reduction process while Pb-Zn-rich fluids flowed through highly permeable sandy conglomerates of primary oxidation state.
(4) Structural systems for controlling oil in eastern-central China: The study for the first time made a systematic classification of the structural systems in the Song-Liao area (latitudinal structural system,Cathaysian structural system, Neocathaysian structural system, longitudinal structural system andepsilon-type structural system); restored the Song-Liao prototype basin since the Paleozoic under thecontrol of tectonics (Cambrian-Ordovician: rift-craton basins; Silurian-Devonian: quasicratonic basins;Carboniferous-Permian: intracraton depression basins; Meso-cenozoic: fault-depression basins).
