关于海洋沉积岩芯中粘土矿物变化与古气候变迁的关系,目前国际粘土界有两种截然不同的看法。一种看法认为海洋沉积岩芯中粘土矿物变化可作为古气候事件的指示,如Jacobs持此观点。另一种看法则认为两者无关,如Maldonado就是这种主张。 笔者同意上述第一种看法。我们对赤道太平洋的两个岩芯和黄海八个岩芯中的粘土矿物进行了综合定性分析和半定量分析(包括X-射线分析、差热分析和电镜观察)。同时还得到了
With regard to the relationship between the changes of clay minerals in marine sedimentary cores and paleoclimate changes, there are two completely different opinions in the international clay community. One view is that changes in clay minerals in marine sedimentary cores may be indicative of palaeoclimate events, as Jacobs holds. Another view is that the two have nothing to do, as Maldonado is such a proposition. I agree with the first view above. We conducted a comprehensive qualitative and semi-quantitative analysis (including X-ray analysis, differential thermal analysis and electron microscopy) of clay minerals in two cores in the equatorial Pacific and eight cores in the Yellow Sea. Also got it
