China's research vessel Haiyang Dizhi-6 recently completed its 16th deep-sea geological survey expedition, according to CCTV News on Monday. The mission has achieved a number of important results in areas including deep-sea geological environment investigations and the research, development, and application of key marine exploration technologies and equipment.

During this expedition, the scientific team employed a variety of geological survey methods and obtained valuable first-hand data and samples, including polymetallic nodules, seafloor rocks, and near-bottom seawater.

Qin Pengbo, a deputy director of the institute of applied marine geology of Guangzhou Marine Geological Survey (GMGS) under the China Geological Survey, said that they discovered high-abundance polymetallic nodules, and in particular obtained approximately 90 kilograms of basalt samples, per CCTV News. These samples provide important support for studying the characteristics of the mantle source region in the area and investigating Earth's deep evolutionary processes.
