西藏卡达铅锌矿地球物理特征及找矿标志

Tibet Card lead-zinc Mine Geophysical Characteristics and Prospecting Marks

矿区大地构造位置位于喜马拉雅构造带江孜-哲古错褶皱束东段山板片北缘,羊卓雍错-宗许错断陷盆地与邛多江变质核杂岩的过渡部位,宗许-马扎拉金锑成矿远景区之西部。其出露地层比较简单,为白垩系拉康组一段(K1l1)及第四系松散沉积物,构造表现上以褶皱和断裂构造为主,另有节理和裂隙,岩浆活动较发育。矿区具有明显的地球物理特征异常带,其解译与地表矿化吻合。找矿标志表现在岩性、构造及矿化等方面。

Mining area tectonic position is located in the Himalayan tectonic belt gyantse - zhe ancient eastern fault fold beam plate of northern mountains,sheep ZhuoYong wrong - zong xu wrong fault basin and Qiong jiang transition part of the metamorphic core complex, Cases of xu - lift Larkin antimony metallogenic prospect areas in the west. The outdoor floor is simpler, for the cretaceous lacan group a（Kl/1） and of quaternary unconsolidated sediments, is given priority to with fold and fracture structure on the structural performance, Otherwise joints and fractures, magmatie activity development. The geophysical characteristics of mining area has obvious anomaly zone, the interpretation to the surface of the mineralization. Performance, in lithologic prospecting,tructures and mineralization, etc
