Abstract

Abstract

The spectral peak parameters of mixed samples with different ratios of MnO content to MnO₂ one were analysed by X-ray fluorescence spectrometer and processing software Peak Fit.Various single spectral peak parameters such as peak position,peak intensity and full width at half marimal were obtained by deconvolution of over lapped spectral peaks.The relationship between the peak parameters and the ratio of MnO₂ content to MnO one was determined.According to the refation,the ratio of MnO₂ content of MnO one in a number of cobalt-rich manganese crusts from the central Pacific seamounts was quantitatively calculated.The results show that MnO₂ content in cobalt-rich manganese crusts increases from the core outwards.It is believed that this tendency has been related to the enhancing activity of Antarctic Bottom Water in this area since Tertiary.
