The invention discloses a comprehensive quantitative
recovery method for a lake deposition environment. The comprehensive quantitative
recovery method comprises the following steps: (1) selecting paleo-climate, paleo-
salinity, oxidation-reduction property, an ancient material source and paleo-
water depth as indexes for recovering the deposition environment; (2) extracting the
rock core sample, andobtaining elements, total rock minerals and X
fluorescence spectrum element data; (3) respectively carrying out Z
standardization processing on the indexes of the paleoclimate, the paleosalinity andthe oxidation-reduction property by applying SPSS
software; (4) carrying out
factor analysis on paleo-climate, paleo-
salinity and
redox indexes subjected to Z
standardization treatment by applying SPSS
software; (5) calculating an ancient material source factor and an ancient
water depth factor; And drawing a comprehensive quantitative
recovery map of the deposition environment. According to the method, the limitation of a single
recovery method can be overcome to a certain extent, and meanwhile, the trend of environment change is more obvious. The whole method is high in
operability, the actual problem in the scientific
research process is solved, a foundation is provided for subsequent geological research, and practical significance is achieved.
