(一)南海锰结核(壳)的分布 这次在南海北部陆坡及中西沙地体上进行岩石拖网时,共采集到锰结核(壳)132kg,在较成功的拖网中,几乎每网都获得锰结核(壳),有些是以较厚较大的锰结壳为主,有的采集到较大的锰结核,有的是在采集到的岩样表面有0.5mm左右的锰结皮。联邦德国在南沙地区的SO23和SO27航次中,至少有4个站位取得了锰结核(壳),这是我国首次在南海发现较大量的锰结核(壳)资源。
(1) Distribution of manganese nodules (shells) in the South China Sea At this time, a total of 132 kg of manganese nodules (shells) were collected during rock trawling on the northern slope of the South China Sea and on the Western and Central Sandlands. In more successful trawls, almost every net was obtained Manganese nodules (shell), some of which are thicker and larger manganese crusts, and some collected larger manganese nodules, and some are collected in the rock sample surface has about 0.5mm manganese crust. Federal Republic of Germany In the Nansha Prefecture SO23 and SO27 voyages, at least 4 stations made of manganese nodules (shells), this is the first time in our country found in the South China Sea a larger amount of manganese nodules (shell) resources.
