摘要:
在海图上早就以“砾石”符号表示了南黄海一带钙质结核(下文简称结核)的存在。但1958年全国海洋综合调查之后,它们的分布范围才初步被确定下来,并以明确的符号标於底质图上。不过始终没有人去探索这些结核的特征和成因。近年来,由於海洋调查的广泛展开,它的存在引起了不少海洋地质工作者的兴趣,相继对它进行了多方面的研究。但在它的成因方面,众说纷纭:有的认为是海底自生的,至今仍在不断地生长;有的则认为,除了自生之外,还有一种结核是属于被海水淹没的黄泛区物质,
Abstract:
The calcareous nodules widely distributed on the sea bed of shallow water in the Yellow Sea and the East China Sea，especially in the Haizhou Bay of the Y e1- low Sea，are a special carbonate deposit，which is found usually in the marine geological in vestigation or in operating by fishing vessels. They have not a certain shape and the diameter rang is from less lmm to several tens cm. There are a lot of organisms living on the nodule.Some of organisms make a lot of round holes on the nodules. Many researchers show interest in the nodules existiag on the sea bed but they have great divergence on their origin, some considered that the calcareous nodules sliould be suthigenic on the sea beds so m e said that their existing relates to the leaching of the matter in the Old Huanghe T fiver during the tow sea levels others held that the nodules should belong to the mical deposit, etc, In fact, so far as our information goes, the calcareous nodules are the continental loess doll su- merged by the sea water.
