Finally, the prospecting criteria and direction of lamprophyres are analysed.
对煌斑岩出露区的找矿标志以及本区的找矿方向作了分析。
Lamprophyres in the Baimazhai nickel deposit are located on the southern segment of Ailaoshan fault belt.
白马寨镍矿区煌斑岩位于哀牢山断裂带的南段，是该条带上新生代富钾火成岩的重要组成部分。
Low REE group and high REE group lamprophyres are 10% and 4% partial melting of the metasomatic enriched mantle.
低ree组和高ree组煌斑岩分别是交代富集地幔约10%和4%部分熔融的产物。
Under the influence of the subduction, the source mantle of the potassic lamprophyres has a high geothermal gradient and oxygen fugacity.
由于这种作用的影响，使钾质煌斑岩的源区地幔处于地温梯度高、氧逸度高的不稳定状态。
Perhaps there are no lamprophyre magmas, and lamprophyres derive from common basic magmas which are contaminated by the crust in their source or the process of emplacement.
而煌斑岩原始岩浆可能并不存在，煌斑岩是普遍类型的基性岩浆在源区或侵位过程中遭受地壳混染的衍生物；
The lamprophyres are widely distributed in Qinling, which are mostly well auriferous. The lamprophyres are occurred in silty slates of Palaezoic Silurian and Devonian systems.
秦岭地区广泛分布有煌斑岩，其主要赋存于古生界志留系与泥盆系的粉砂质板岩中，大部分含金较高。
