Abstract

The method is suitable for the technical field of rock geochemistry, and provides a shale weathering index construction method and device. The method comprises: obtaining a first parameter of a rock core sample and a second parameter of an outcrop sample, and comparing the first parameter with the second parameter, wherein the first parameter and the second parameter both comprise organic geochemical parameters, rock physical parameters, main trace elements and rock mineral compositions; determining a plurality of key parameters indicating the shale weathering degree according to the comparison result of each parameter in the first parameter and a corresponding parameter in the second parameter; and determining the weight of each key parameter through an improved feature vector method, andconstructing a shale weathering index indicating the shale weathering degree according to the weight. According to the shale weathering index construction method and device provided by the invention,the shale weathering degree can be accurately evaluated.

Description

technical field [0001] The invention belongs to the technical field of rock geochemistry, and more specifically relates to a construction method and device for a shale weathering index. Background technique [0002] Since Clayton et al. studied the weathering characteristics of black shale, the research on the influence of black shale by chemical weathering has received a lot of attention, and the research focus is mainly on the change between weathering and rock mineral element composition. Some scholars have also discussed the characteristics of organic matter and carbon isotope changes in the process of weathering. The chemical weathering index, which is closely related to the degree of rock weathering, is widely used to analyze soil development, climate change, In the study of tectonic evolution, element activity law, etc., it is an important index to clarify the element activity law of epigenetic process. The criterion of shale weathering degree and the influence of w...
