摘要
松岭矿区处于南岭EW向构造带与武夷山NNE向断褶带的复合部位。区内有石英斑岩型、隐爆角砾岩型和石英细网脉型三类锡矿体;石英斑岩型锡矿体1条呈脉状,长1200m,平均厚度3.55m,平均品位0.422%;隐爆角砾岩型锡矿化体5条,呈透镜状或似层状,平均厚度2.3m,平均品位0.282%;石英细网脉型锡矿体12条,平均厚度1.2m,平均品位0.310%。本文重点阐述了矿床的地质特征,分析了成矿条件和成矿机理,建立了三位一体成矿模式,探讨了成因。对矿区进一步找矿及外围找矿等有一定启发意义。
Songling mining area locates at the composite parts of Nanling EW-trending tectonic belt and Wuy-ishan NNE-trending fault-fold belt.In this area three types of tin ore-bodies are found which are quartz por-phyry type,hydrothermal breccia type and fine quartz stockwork type.There is 1 quartz porphyry type tin ore-body which occurs in vein and has length of 1200m and has average thickness of 3.55m and average grade of 0.422%.There are 5 hydrothermal breccia type tin ore-bodies which occur in lenticular or stratoid struc-ture and have average thickness of 2.30m and average grade of 0.282%.There are 12 fine quartz stockwork type tin ore-bodies which have average thickness of 1.20m and average grade of 0.310%.This paper elabora-ted on geological characteristics of the deposit,and analyzed its metallogenic conditions and mechanism. Through establishing a metallogenic model of trinity,genesis of the deposit was explored.The results a-chieved in this paper are enlightened to further and periphery prospecting works.
