笛给矿区位于西藏自治区墨竹工卡县尼玛江热乡,是冈底斯火山岩浆弧的重要组成部分,强烈的构造活动形成大量以斑岩型为主的矿床。1矿区地质背景矿区出露地层简单,主要为二叠系下统洛巴堆组、二叠系上统旁那组、古近系典中组,及第四系。矿区位于麦隆岗-旁那断片,构造发育以断裂为主,褶皱次之,次级裂隙与矿化关系密切。矿区二叠系地层和古近系地层中火山岩均较发育,二叠系火山岩主要为中酸性火山碎屑岩及熔岩,主要岩石类型有:安山岩、
The flute to the mining area is located in Nimajianghe village of Mozhugongqiaoxian in the Tibet Autonomous Region and is an important part of the magmatic arc of the Gangdese volcano. The intense tectonic activity formed a large number of deposits characterized by porphyry-type deposits. 1 Geological Background of Mining Area The exposed strata of the mine area are simple, mainly composed of Permian Lower Lobolith Group, Permian Upper Paleo-Group, Paleogene Palaeo-Central Group and Quaternary. The mining area is located in the Meilonggang-Piannian fault. The structure is dominated by faulting and folds, while the secondary fissures are closely related to mineralization. The Permian strata and Paleogene strata in the mining area are well developed. The Permian volcanic rocks are mainly acidic volcanic clastic rocks and lava. The main rock types are andesite,
