摘　　要：栾川马壮钼矿床位于华北地台南缘与秦岭褶皱系接合部位,是近年来在豫西钼多金属成矿带上发现的又一中型钼矿床。矿体产于燕山期老定沟小岩体的外接触带,特别是岩体近围的老定沟背斜核部的蚀变带是形成斑岩-矽卡岩型钼矿床的有利部位。本文在讨论矿床成矿地质背景、矿床地质特征的基础上,对矿床成因、控矿因素及区域找矿标志进行了探讨,指明了该类矿床的进一步找矿方向。Luanchuan Mazhuang molybdenum deposit lies in the junction place of the southern margin of North Chi-na Carton and Qinling fold system. It is another medium-sized molybdenum deposit found in the molybdenum poly-metallic etallogenic belt in western Henan in recent years. The orebody appears in the outer contact zone of the Laodinggou small rock body in the Yanshan epoch, especially the alteration zone of the core of Laodinggou anticline near around the rock body is the advantageous position of the formation of the porphyry-skam type molybdenum de-posit. On the basis of discussion about geological background and deposit geological features, the deposits genesis, ore-controlling factors and regional prospecting marks were discussed, in order to point out the further prospecting direction of this type of deposit.
