摘要
姑俄夸锰矿属扬子地台西缘之松潘—甘孜地槽南缘凹陷盆地边缘沉积;锰矿赋存于下三叠系菠茨沟组上段(T1b2),严格受地层、岩性控制;整个含锰岩系显示海退式沉积特征;综合研究认为姑俄夸锰矿属沉积变质锰矿床;提出4种找矿标志。
The Guekua Mn deposit lies in the margin of a depression basin on the southern margin of the Songpan-Garzê geosynclines.The Mn deposit lies in upper of the Lower Triassic Bocigou Formation（T1b2）,and are strictly controlled by the stratum and lithology;The manganese-bearing rock series indicated that Regressive sedimentary character;The comprehensive evaluation showed that the deposits belongs to sedimentary metamorphic type with giant reserves;put forward 4prospecting criteria.
