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.

Key words: ejecta, siderite concretions, Taihu lake origin
