Abstract:By showing exhaustive geological results and practical evidence, this article discovers the latest geological event in the lake for the first time-volcanic extrusion and explosion activity, and determines its date and location. The above-mentioned demonstration and the geological information accumulated by the writer for several decades will make it possible to re-understand the evolvement history and manner of the Taihu Lake area, especially after Mesozoic Era, and outline the pre-conditions and intrinsic causes for the lake-basin formation. The Quaternary system changes, archaeological achievements, fossil record of ancient spinal animals and recording on ancient books concerning this area all indicate that the lake actually experienced sinking phenomenon, sinking rate and lake formation. In the end, the author, by providing exhaustive information, expounds the future evolvement law of the Taihu Lake and its adjacent area for planning and developing of the local economy.
Keywords:genesis of Taihu Lake  volcanic explosion-effusion  magma chamber  remote sensing.
