Abstract:In the past 60 years, Shandong Exploration Bureau of Geology and Mineral Resources(SDGM) insists on prospecting to serve the country as own duty, to provide resources guarantee for the economic construction of Shandong province. So they made great achievements in prospecting. This paper comprehensively summarizes the important prospecting achievements and latest technological advances of deep and concealed prospecting by SDGM. In the 20th century, a new type of gold deposit of Jiaojia type was discovered, and onethird of the country's gold reserves was proven. China's first primary diamond deposit and the largest sapphire deposit had been discovered, and a batch of largescale coal deposits, iron ore deposits, nonferrous metal deposits and nonmetal deposits had been found. Since the 21th century, SDGM implement National Exploration and Development Planning in the innerprovince, outerprovince and overseas. In the innerprovince, outstanding achievements in deep prospecting has been made, and more than 10 large gold deposits with a reserves of over 100t have been discovered, especially a world's largest undersea gold deposit with 470t reserves has been detected. In the outerprovince, important coal deposits and polymetallic deposits have been discovered in Xinjiang and Inner Mongolia respectively. In other countries, such as Congobrazzaville, Peru, Australia, Zimbabwe and Kenya, a batch of largescale potash, iron, diamond and diatomite deposits have been detected. A series of deep and complex condition prospecting methods are developed and established, such as stepwise prospecting method for deep gold deposits.
