中国自然资源部发布了过去二十年海洋地质调查成果，绘制了海底沉积物中数十种元素的分布图集，包括稀土、铁、锰和铜。国家广播电视台央视报道称，该图集覆盖渤海、黄海和东海，超过2万观察点的数据被描述为最全面、最可靠的地球化学数据集。青岛海洋地质研究所研究员窦延光表示，这有助于精准定位矿产资源并划定海洋保护红线。
中国自然资源部于周二发布了海洋地质调查成果，央视报道称该图集记录了渤海、黄海和东海海底沉积物中元素的分布情况。
该图集基于超过20,000个观察点的数据，被誉为中国迄今为止该海域最全面、多维度和可靠的地球化学数据集。窦延光表示：“通过[绘制]元素分布，我们可以……精准锁定海底矿产资源，减少盲目勘探。”他还指出，该图集有助于快速识别污染区和生态敏感区，划定海洋保护“红线”并管理污染风险。
图集覆盖中国内海渤海，以及位于中国大陆与朝鲜半岛之间的黄海，还有中日存在长期领土争端的东海，特别是中国称作钓鱼岛、日本管辖的尖阁诸岛地区。同时，日本正加紧开采稀土，一支日本深海探险队携稀土样本返航。
Japan is speeding up a decade-old plan to extract rare earths from the deep seabed, driven by efforts to reduce reliance on Chinese supplies. A state-owned vessel is set to return to port this month after installing equipment in Japanese waters near a coral atoll 2,000 kilometers from Tokyo, with tests to pull metal-bearing mud potentially starting as early as February 2027. The initiative underscores the country's focus on economic security.

Japan has begun a five-week experiment to extract rare earth minerals from the deep seabed off Minamitorishima Island, aiming to reduce reliance on China for critical materials. The project, aboard the research vessel Chikyu, marks the first prolonged collection effort at such depths and highlights tensions between energy security and environmental risks. Officials hope it will support Japan's carbon neutrality goals by 2050 while bolstering industrial competitiveness.
China has strongly protested the Philippines' decision to assign local names to more than 100 maritime features in the Kalayaan Island Group, calling it illegal. Chinese Foreign Ministry spokesperson Mao Ning said Beijing firmly opposes the move and will take necessary steps to defend its claims. The reaction follows an executive order signed by President Ferdinand Marcos Jr.

The International Seabed Authority is convening in Jamaica this week to discuss finalizing rules for deep-sea mining by year's end. Indigenous advocates push for inclusion of their rights and cultural ties to the ocean amid concerns over environmental impacts. The accelerated timeline responds to U.S. President Donald Trump's policies promoting mining outside international frameworks.
Researchers at Stanford University have developed the first worldwide map of rare earthquakes occurring deep in Earth's mantle, rather than the crust. These elusive events cluster in regions like the Himalayas and near the Bering Strait. The study, published on February 5 in Science, identifies hundreds of such quakes and introduces a new method to detect them using seismic waves.

On January 28, 2026, China's Zijin Mining announced a US$4 billion takeover of Allied Gold's three African mines. On February 3, Swiss mining giant Glencore entered talks to sell a 40 per cent stake in its Democratic Republic of Congo (DRC) copper and cobalt operations to the US-backed Orion Critical Mineral Consortium. These developments underscore the escalating competition between China and the United States over critical minerals.
