| 摘 要： | 陕西省南部发育大量辉绿岩体，该套岩性组合形成于大陆边缘裂谷构造环境，岩浆物质来源于下部地壳和上地幔，与辉绿岩体有关的钛磁铁矿体发育，仅紫阳—岚皋一带已达到大型规模，同时伴生有益组分可综合回收利用。矿体均赋存在侵入于早古生代地层中的基性辉绿岩体内；规模大的岩体一般具分异现象，分异现象明显的岩体内钛磁铁矿化明显。规模较大分异较好的辉绿岩体，是找矿有利地区。

| Abstract: | There is a lot of diabase in southern part of Shaanxi Province. The lithological composition formed in continental margin rift valley. The magmas derived from the lower crust and upper mantle. The titanomagnetite related to the diabase in Ziyang-LanGao area has formed large-scale with a beneficial component can be recycled. Ore bodies are hosted in the early Paleozoic strata in the basic diabase. Usually the large-scale of the rock mass has differentiation. Titanomagnetite mineralized obviously in the rock mass with obvious Differentiation. The larger-scale and the better differentiation diabase is more helpful for prospecting. |
