摘要
大兴安岭中南段华力西褶皱带是我国北方重要的锡多金属成矿带。已发现了许多大中型锡矿床、锡多金属矿床、铅锌矿床、铜矿床等。这些矿床形成与花岗岩有密切成因联系。本文较详细地阐述了花岗岩产出的地质背景，各期次花岗岩的地球化学特征。
The south middle part of the Greater Xing’an Mountains,where many large middle scale tin deposits,lead zinc deposits and copper deposits are discovered, is an important tin-polymetal metallogenic belt in the north of China. The tin polymetal mineralization is closely related to granites. The geological setting and geochemical characteristics of the different aged granites are discussed in detail and the geological and geochemical criteria of granites related to mineralization are proposed.
