北秦岭富水基性杂岩体位于商丹断裂带北侧，为新元古代深成杂岩体。通过１∶５万地质填图将该杂岩体划分为５个岩石谱系单位：金盆中细粒变辉石岩单元、黑潭沟细粒暗色变辉长岩单元、马槽沟中粒变辉长岩单元、丁家沟中粒变辉长闪长岩单元和八里湾变角闪石黑云母二长岩、正长岩单元，合并为一个序列———富水序列。依据接触关系、包体特征确定了其侵入序次，构成了比较完整的岩浆演化序列，在岩石矿物组成、岩石化学成分、微量元素及稀土元素组成上具有明显的同源岩浆演化特征，形成于北秦岭新元古代活动大陆边缘的岛弧构造环境。
The North Qinling Fushui-based complex is located in the north of Shangdan fault zone and is Neoproterozoic deep complex complex. By 1: 50000 geological mapping, the complex body is divided into five rock pedigree units: fine-grained altered rock units in the gold basin, fine-grained black-altered gabbro units in the Heitan Formation, Gabbro unit, dachanggou granulite gabbro diorite unit and Baliwan gabbro amphibolite biotite monzonite, syenite unit, merged into a sequence --- water-rich sequence. Based on the contact relationship and the characteristics of the inclusions, the sequence of intrusions was confirmed, and a relatively complete magmatic evolution sequence was formed. There are obvious evolution features of homogenous magmatism on the rock mineral composition, rock chemical composition, trace element and rare earth element composition.
