中文摘要 鍶釹同位素為良好的來源示蹤劑,台灣海峽沉積物來源為近年來備受科學界切關議題。本研究分辨台灣海峽沉積物來源,從水平剖面變化探討源至匯及洋流對於沉積物分布的影響。20個樣品系統性採集台灣海峽表面沉積物並對比台灣本島及中國主要出海口處,透過系統性選樣位置,達到觀察化學組成與同位素比值隨空間的變化分布。為進行岩屑相的分析,利用連續性的淋洗萃取步驟移除碳酸鹽類和其他吸附物。利用感應耦合電漿質譜儀分析主要、微量元素及鍶釹濃度,並利用多接收器感應耦合電漿質譜儀(MC-ICP-MS, Thermo-Fisher, Neptune) 量測鍶釹同位素比值。87Sr/86Sr結果顯示分佈範圍0.71776 - 0.72737,可能存在端源成分包括來自台灣本島,珠江和長江三角洲的沉積物混合。其中中國東南沿海附近的樣品大部分顯示較高87Sr/86Sr比值可至0.72737,而台灣平均鍶同位素比值較低範圍落在0.71785 - 0.72048,結合ɛNd同位素範圍-10至-14兩者差異可利用於判斷沉積物來源與貢獻比例。經由岩屑相87Sr/86Sr比值結合εNd的混合圖表,我們可以計算出不同來源的貢獻比例。
英文摘要 Sr and Nd isotopes are excellent tracers for various geochemical processes, in particular for provincial identification. The sediments source-to-sink pathways and the spatial variation of lateral fluxes in Taiwan Strait have been considered as important issues for past decades.
Surface sediments provide useful diagnostic details among ocean currents, sources and transportation processes. In this study, 20 surface sediments were collected from the Taiwan Strait including near estuary stations in western and southwestern coast of Taiwan, as well as Pearl River and Yangtze River in China. To simplify the mixing scenario, carbonate and adsorption phases of sediments were chemically removed before acid digestion. Concentrations of major and trace elements and Sr, Nd isotope of the residual solids were measured by ICP-MS and MC-ICP-MS, respectively.
The 87Sr/86Sr ranged from 0.71776 to 0.72737 shows distinct end-members mixing, including sediments from Taiwan Island, Pearl River and Yangtze River. The samples near the southeastern coast of China show higher ratios up to 0.72737, indicating sediments derived from Yangtze River. On the other hand, most of the Taiwan Strait stations show lower 87Sr/86Sr (0.71785 to 0.72048). The results of ɛNd are distributed between -10 and -14. From the 87Sr/86Sr versus εNd of the detrital sediments mixing diagrams we can explore different mixing trends in the Taiwan Strait and to quantify the contribution for each source.
