The present paper tries to review the international, as well as Chinese literature to show recent progress in the high-resolution studies of late Quaternary environmental changes, preferentially in offshore areas. Although the review covers all the millennial, centennial, decadal and interannual time scales, itS emphasis is laid on "sub-Milankovitch " climatic variations including Heinrich events and Dansgaard / Oeschger events. A special discussion is devoted to calibration of radiocarbon datings as a Prerequisite for a precise chronology of environmental events.The paper is concluded with three suggestions to Chinese colleagues: 1) to be selective in application of high-resolution approaches to fossil records and to be aware of the specific requirement for high-resolution studies; 2) to develop our own scientific thoughts in high-resolution Paleoenvironmental studies on the basis of regional specific features; and 3) to apply the high-resolution approaches to pre-Quaternary sedimentary sequences. %K high-resolution records %K paleoenvironment %K Sub-Milankovitch cyclicity %K calibration of radiocarbon datings
