1982,年中国科学院海洋研究所在东海海域进行了海底沉积物的调查;之后,对所取沉积物样品开展了多方面的研究工作,其中在表层碎屑矿物的研究中发现了一种新矿物。它产在东海东部的冲绳海槽南端,即中国台湾省东北50公里处的钓鱼岛附近(123°22′E,25°26′N)的海底表层沉积物中(见图)。它是在自然界中首次发现的一种新矿物,根据其产地命名为钓鱼岛石(Diaoyudaoite)。该矿物于 In 1982, the Institute of Oceanology, Chinese Academy of Sciences conducted a survey of seabed sediments in the East China Sea. After that, many studies were carried out on the sediment samples taken. Among them, a new mineral was discovered in the study of surface detrital minerals . It is produced in the seabed surface sediments near the Diaoyu Island (123 ° 22’E, 25 ° 26’N) at the southern tip of the Okinawa Trough in the eastern part of the East China Sea, which is 50 km northeast of Taiwan Province of China (see photo). It is the first new mineral found in nature, named Diaoyudaoite according to its origin. The mineral in
