Characteristic of rare-earth element distributions in mud volcanic waters

The original results on the distribution of rare-earth elements in the waters of mud volcanoes in Sakhalin Island, Taman Peninsula and Azerbaijan are presented. It has been shown that mud volcanic waters with total content of rare-earth elements less than 0.5 mcg/l are enriched with heavy lanthanides and characterized by a deficiency for Cerium. The Yuzhno-Sakhalinsk mud volcano demonstrates higher rare-earth element content in active griffons according to our study.

Geologic Feature of Shilipo Copper Deposit in Xinjiang

The Eastern Tianshan is a type of mineralization belt, Shilipo copper, deposit is new discoveried one at Eastern Tianshan, bearing in maroon basaltic tuff. Some basalt shows red color, which has certain similarity to hematite mineralization development in the Jiweinuo copper deposit. From geochemical characteristics analysis, it is proven that the formation of Eastern Tianshan copper relates to the mineralization of the mantle plumes. That only the Emeishan basalt in Sichuan Province contains the copper in China, which shows the preliminary scale was reported and after that, caused the heated debates. The most thought that the copper has the relation to the mantle plumes. Similar deposit was reported in America as well, such as the Jiweinuo Cu deposit in Subilier Lake. Such make us consider if the formation of the belted copper deposit in Dongtianshan has the relation to the mantle plumes. For confirm this result, we respectively chose two basalt samples from Shilipo and Heilongfeng mineral occurrences in order to analyze their constant, trace and rare earth element content and preliminarily research their geochemical characteristics.
