额尔古纳地区是一个重要的有色、贵金属成矿省． 区内金、银、铅、锌、铜等矿产具明显分带性， 可划分为耳布尔、上护林及恩和３个成矿小区， 分别以银铅锌、铜多金属、金为主． 该区在Ｊ３—Ｋ１ 时期发生了强烈的构造－岩浆活动， 这些矿产在成因上均与Ｊ３—Ｋ１ 时期酸性岩浆侵入作用密切相关， 成矿热液主要来源于岩浆热液． 矿体主要受次级张性裂隙控制， 以ＮＷ 向为主． 成矿时代主要为Ｊ３ —Ｋ１ ．
The Ergun area is an important non-ferrous and precious metal mineralization province. The area of gold, silver, lead, zinc, copper and other minerals with obvious zonation, can be divided into ear Boolean, upper shelter forest and grace and three mineralized areas, respectively, silver, lead and zinc, copper and more metal, gold-based. The strong tectono-magmatic activity took place in J3-K1 period. The origin of these minerals is closely related to the intrusive magmatic intrusions during the J3-K1 period. The hydrothermal fluids mainly originated from magmatic hydrothermal fluids. The orebodies are mainly controlled by secondary tension cracks, dominated by NW direction. The mineralization age is mainly J3 -K1.
