中文百科
锰结核![]() ![]() ![]() 锰结核(manganese nodules),亦称为多金属结核(Polymetallic nodules),为海底岩石凝固物,由铁或锰的氢氧化物以一个核心凝固而产生。其核心可能极其微小,并有可能因为结晶作用而完全转变为锰矿物。当锰结核为肉眼可见时,它可以是细小的微化石(放散虫门 Radiolaria 或有孔虫门 Foraminifera 生物)外壳、磷酸化的鲨鱼牙、玄武岩残骸或早期凝固物的碎片。 锰结核的大小差距很大,由微小得只能用显微镜见到至大的球状物大于二十厘米阔。但大部分锰结核的直径为5至10厘米,约为一个马铃薯的大小。其表面平滑,部分则较粗糙,椭圆状(多疙瘩的)或不规则的。其底部因为埋藏在沉积物下而比顶部更为粗糙。
英语百科
Manganese nodule 锰结核![]() ![]() ![]() Polymetallic nodules, also called manganese nodules, are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. The core may be microscopically small and is sometimes completely transformed into manganese minerals by crystallization. When visible to the naked eye, it can be a small test (shell) of a microfossil (radiolarian or foraminifer), a phosphatized shark tooth, basalt debris or even fragments of earlier nodules. |
