陕西略阳煎茶岭镍矿位于勉略结合带上，成矿区带属勉略华力西-印支蛇绿杂岩 Mn-P-Cr-Ni-Au成矿亚带之略阳金家河-汉中天台山锰磷镍远景区内；矿床成因为岩浆熔离-热液改造型，赋矿岩体为元古代(Pt3)变质(蚀变)超基性岩，早期含镍超基性主岩体是成矿基本场所，后期中酸性岩对超基性主岩体进行改造，总体上为低品位硫化镍大型矿床，伴生低品位Co。通过对矿床大地构造位置、岩体特征、矿体特征等分析，总结了矿床控矿因素及找矿标志特征，认为该矿床成矿作用主要受镁质超基性岩、构造破碎带控制，中酸性侵入岩提供了镁质超基性岩再造成矿所需的热动力。

Lying in the Mianxian-Lueyang suture zone,Jianchaling nickel ore-forming belt locates inside the Jinjiahe-Tiantaishan Mn-P-Ni prospecting area in a subzone of Mn-P-Cr-Ni-Au mineralization of Mianxian-Lueyang Hercynian-Indosinian ophiolite rock;the origin of the deposit belongs to magmatic liquation-hydrothermal alteration. The main rock is the Proterozoic metamorphic ultrabasic rock, and early nickel-bearing ultrabasic main rock which was later transformed by acidic rocks is the basic metallogenic place.On the whole,the deposit is a large low-grade nickel sulfide ore deposit,associated with low-grade cobalt.By analyzing the ore geotectonic location,the rock body characteristics and the ore body characteristics,the ore control factors and ore-prospecting indicators are concluded.It is believed that the mineralization is controlled by the magnesium ultrabasic rock and the structural fracture zone, and the intermediate-acidic intrusive rock provided the reforming thermal dynamic power for the magnesium ultrabasic rock.
