加多岭玢岩型铁矿床位于治多-江达-维西陆缘弧带，处于波罗-德登背斜中部。矿区内出露主要地层为晚三叠世洞卡组(T3dk)、晚三叠世甲丕拉组(T3j)，岩性主要为灰岩，砂质灰岩。岩浆岩主要为印支期闪长岩、闪长玢岩。矿区构造较复杂，主要断裂及挤压带为成矿提供了较好的容矿导矿构造。本文通过介绍区域地质背景，矿区地质特征，初步分析了加多岭铁矿床的成因，认为该矿床属于玢岩型矿床。
加多嶺玢巖型鐵礦床位于治多-江達-維西陸緣弧帶，處于波囉-德登揹斜中部。礦區內齣露主要地層為晚三疊世洞卡組(T3dk)、晚三疊世甲丕拉組(T3j)，巖性主要為灰巖，砂質灰巖。巖漿巖主要為印支期閃長巖、閃長玢巖。礦區構造較複雜，主要斷裂及擠壓帶為成礦提供瞭較好的容礦導礦構造。本文通過介紹區域地質揹景，礦區地質特徵，初步分析瞭加多嶺鐵礦床的成因，認為該礦床屬于玢巖型礦床。

Jiaduoling’s porphyrite-type iron deposit is located in Zhiduo-Jiangda-Weixi precontinental arc belt, lie in the mid position of Boluo-Dedeng anticline. The main exposure stra in the digging is Dongka formation, Late-Triassic (T3dk), Jiapoula formation, Late-triassic (T3j). The lithology in mainly limestone, sandy-lime. The magmatic rock are mainly diorite, diorite porphyrite of indo-china period. There are complex structure in mining area, the mainly fracture and compressive zone provide high-class ore-bearing zone and ore-fluid channel way. In this paper , based on the regional geologic background, the geologic characteristic of mining area, the genesis of the Jiaduoling iron deposit is analyzed and conclude that it is porphyrite-type deposit.
