| 摘 要： | 近年来，在大兴安岭北部发现近10处岩金矿床（点），大兴安岭北部金矿形成于中生代，且其成因与中生代岩浆活动关系密切，对本区金矿的成因类型二重限定性分类方案的原则是以Au所赋存的岩石类型（热液岩或蚀变岩）为第一依据。成矿温度作为第二依据。大兴安岭地区金矿在不同构造单元成因类型具有较大差别；在额尔古纳地块和上黑龙江盆地形成多种中温蚀变岩型金矿，在其南侧的增生带中形成了低温热液石英岩型金矿。 |

| Abstract: | About 10 gold deposits have been found in the northland of Great Xing'anling.The gold deposits in this area formed in Mesozoic, and its genesis is closely related to Mesozoic magmatic activity.The principle of the binary determined classification of the gold deposits is that the rock type,in which the gold deposits occurred,as the first foundation,and the metallogenic temperature as the second one.The genetic types of gold deposits of different tectonic units are different.The mesothermal altered rock type gold deposits are found in Ergune massif and Shangheilongjiang basin,and epithermal quartzite type gold deposits are found in accreted belt,which located in the south of the two tectonic units. |
| Keywords: | gold deposit genetic type temporal and spatial distribution Heilongjiang Inner Mongolia |
