河南省商城县碾子湾矿区，位于秦岭-大别山中央造山带的东部，桐柏-大别构造亚带东段。本区的矿床形成与其所处的特殊大地构造位置和地质演化背景有密切的关系。在区域范围内，发育有四个大型的、产状平缓的拆离断层带，它们将造山带地壳划分为垂向叠置的五个构造岩石单位(据索书田等)。通过详细的野外地质调查和室内研究，确认了在碾子湾矿区内存在三个构造岩石单位：核杂岩单位(CC)、超高压单位(UHP)、高压单位(HP)。各单位之间都发育有大型的拆离断层，有利于成矿元素在拆离断层中富集，因而，对矿体的形成有重要的控制作用，它们是矿区重要的控矿因素。测区内可见花岗岩、片麻岩、糜棱岩和榴辉岩四类岩石。文中讨论了花岗岩的类型、产状、构造式样特征及变质、变形特征，重点研究花岗岩所在的具体部位、分布范围，分析花岗岩的类型、结构，构造背景、形成演化以及与成矿作用的关系。

Nianziwan mining area of Shangcheng of Henan is located at the east section of Tongbai-Dabie structural sub-area which is to the east of the central orogenic belt of Qinling-Dabieshan Mountain.The de-posits in this area are closely related to its unique geotectonic location and geological evolution background. Through detailed field geologic survey and indoor research,it is verified that there are three structural rock units inside Nianziwan mining area:core complex unit (CC),ultra-high pressure unit (UHP)and high pres-sure unit (HP).Between the units,there are large-scale detachment faults which are in favor of the enrich-ment of ore-forming elements in the detachment faults,and it has important control effects to the forming of ore-bodies.The relationship between granites and mineralization in this area is also discussed.
