摘要
东坪金矿是我国首次发现的赋存于碱性杂岩体中的新类型金矿.金矿化与肉红色钾微斜长石化和硅化有关.矿物组合以自然金—多金属硫化物—金碲化物—氧化物为主.矿床成因为碱性杂岩体重熔、交代,钾长石化蚀变岩型.
Being a new deposit type first found in China, the Dongping gold deposit occurs in alkali-Complex rocks, with its mineralization related to yellowish pink-kali-microc linization and silicification. Mineral assemblage consists cf mainly native gold, polymetallic sulfides, tellurides of gold and oxides. The origin of the deposit belongs to the altered rook type bearing a relationship with the anatexis, metasomatism and kali-feldsparization alkali complex rocks.
