VLADIVOSTOK, March 6 (Xinhua) -- A group of scientists from Russia, China, the United States and Australia have jointly explored a massive amount of rare metal in the Asian Pacific region's coal field, a Russian university website said in a report on Monday.

"The research was conducted in the metal-bearing coal field in Primorsky Krai, located in East Russia, and the southern part of China," according to the report on the Far East Federal University (FEFU) official website.

Scientists concluded, due to the ancient and modern geological process, some coal fields were subjected to mineralization, and could contain over 10 types of rare metal," the FEFU's press-service confirmed in the report.

The joint exploration into the geological resources in the region was aimed at studying and extracting precious elements such as zirconium, niobium, uranium and rare-earth metals, which are strategically important for high-tech production, said the report.

The participating Russian scientists were from the FEFU School of Engineering and the Russian Academy of Sciences (RAS).

The scale of the natural process was enormous and the ores' economic benefit might be significant, said Victor Nemchaev, a senior researcher with the Gemological Lab of Far East Geological RAS's Institute.
