| 摘 要： | 本期刊登了黄志诚和刘冠邦有关太湖“溅射物”的讨论文章。该文从沉积学观点，对太湖某些沉积物及结核开展了
研究工作，确定了沉积成因菱铁矿结核的存在, 并据此对我们在2009 年提出的太湖“溅射物”冲击成因观点提出质疑。这
些非溅射物结核的新资料，为进一步深入对比研究溅射物提供了某些参考。本文根据溅射物的外形、内部特征以及同位素
资料，与非溅射物结核进行了初步对比，结果显示对太湖“溅射物”的不同结论可能与研究样品差异有关, 相关研究工作
还值得进一步深入下去。

| Abstract: | In this issue,Huang Zhicheng and Liu Guanbang(2012) published their results of several sediment and concretion samples from the Taihu area in Jiangsu Province.From a sedimentological point of view,they suggest that the stuided siderite concretions are of sedimentary origin.These non-ejecta samples are different from our studied samples of ejecta origin(Wang et al.,2009),but provide a good reference for a comparative study of the impact ejecta.The results indicate that these two types of samples have different shapes,internal structure characteristics,and C-O isotopic compositions.Therefore,their data and conclusions did not provide any solid evidence to against our previous statement for an impact ejecta origin for some certain Taihu samples,and we suggest that further detailed work are needed to solve this problem. |
