1983年6月我国在大洋锰结核调查中,在洋底采集到一块海底砾石(见照片).砾石岩性为玄武岩,所在站位为;175°01.39’W,8°51.09’N,水深为5932.5米.底质为深海褐色粘土.砾石是由拖网采集,拖网中还采集到一些锰结核.
In June 1983, a submarine gravel was collected on the ocean floor from a marine manganese nodule survey in China (see photo). The gravel lithology is basaltic, with a station of 175 ° 01.39’W and an 8 ° 51.09’N water depth of 5932.5 meters. The sediment is deep-sea brown clay. The gravel is collected by the trawl and some manganese nodules are also collected in the trawl.
