Abstract

The invention discloses a method for analyzing the taenious cycle change of a paleoclimate substitution index of continuous sediment. According to the method, the characteristics of the other-generation cycle information are effectively described, then the paleoclimate background experienced in the sedimentary profile forming process is analyzed, and a basic technical support is provided for deeply analyzing differences existing in paleoclimate region comparison and promoting global change research. According to the method, the amplitude and degree of the paleoclimate relative change process on the section are clearly analyzed; a plurality of other cycles are relatively simply and clearly separated, and the method plays an important role in analyzing the influence of external factors such as paleoclimate and a control mechanism. According to the method, the problems that in the prior art, due to superposition of other cycles and authigenic cycles in comprehensive information of paleoclimate substitution indexes, effectiveness of paleoclimate information is strongly interfered, and accuracy of paleoclimate reconstruction result analysis and global comparative research are affected are solved.

Description

technical field [0001] The invention relates to the technical fields of geology, sedimentology and paleoclimate global change, in particular to an analysis method for the change of alternative cycle of continuous sediment paleoclimate proxy index. Background technique [0002] Global climate change is one of the major issues of international environmental diplomacy and national sustainable development. Sediments on the earth's surface, such as loess, paleosol, deep-sea deposits, ice cores, lakes, peat, stalagmites, etc., contain a wealth of global change information such as climate and environment, and play an important role in reconstructing past global change history and predicting future global change trends. play a vital role. [0003] Paleoclimate is an offshoot of past global change. A major source of paleoclimate information is paleoclimate proxy indicators in sediments, such as: rock mineral indicators, biofossil indicators (sporopollen, phytoliths, foraminifers, o...
