新疆雅满苏东南河铁矿地质特征及成矿规律研究

摘要

In order to correctly estimate the ore body shape,occurrence and extension of the ore body in the Yannong southeastern region of Xinjiang,to ensure the effective geological survey of the area,the geological characteristics and metallogenic regularity of the iron ore in the southeast of the Yalong Su Dongan River were studied.The study shows that the orebody is found in the black marble slender gneiss and dolomite marble,so that in the exploration work,along the black skewed gneiss,dolomite marble layout project,to establish the direction of investigation;Rock fault scratches and the tendency and direction of production,in the exploration process,to determine the ore body was "bean-shaped" or "flat-like" to the south-east side of the side,so the deployment of drilling works,according to the exploration line from the ore outcrop distance design to adjust the depth of different drilling,thereby reducing the amount of engineering,and effectively guide the layout of geological exploration work.%为了正确地推测新疆雅满苏东南河地区矿体形态、产状及延伸,确保有效对该地区进行实际地质勘查,对雅满苏东南河地区铁矿地质特征及成矿规律进行了研究.研究得出:矿体赋存于黑云斜长片麻岩、白云石大理岩中,从而在勘查工作中,沿黑云斜长片麻岩、白云石大理岩布置工程,确立勘察方向;根据岩石断层擦痕以及产状倾向和走向,在勘查过程中,判定矿体呈“豆角状”或“扁担状”向南东方向侧伏,因此在部署钻探工程时,根据勘查线离矿体露头远近设计调整不同钻孔深度,从而减少工程量,有效指导地质勘探工作的布局.
