The three ore belts of Kubusu gold deposit all were preduced in dikes of diorite porphyrite and granodiorite porphyry.

库布苏金矿床的三个金矿带均产于闪长玢岩和花岗闪长斑岩内。

According to petrologic analysis of 18 samples of altered rock, phlogopite rock , with regard to its B 2O 3 content, it is generally restricted to the outside of the ore bed, having certain ties with the boron minerlization while no ties are found in altered rock of the same type associated with veins of diorite porphyrite.

其中金云母岩多分布在含矿层外带，通过对 1 8件金云母岩样品中B2 O3含量分析，表明正常蚀变岩中的金云母岩与硼矿有一定的关系，而由闪长玢岩脉体侵入影响下形成的金云母岩则与矿化无关。

The deposit is known for higher resistivity of the ores than the wall rocks, high mean content (1612 x 10 -6 ) of strontium in the tuff and ever higher (4597 x 10 -6 ) in the porphyrite, and prominent biogeochemical anomaly associated with the plant ecologic variation in the mining area.

根据锶矿为强电阻体，矿石与围岩电性差异大，龙王山组晶屑凝灰岩中锶的平均含量高（1621×10－6），安山玢岩含锶量更高（4597×10－6），矿区生物地球化学异常显著，常见的植物生态呈现变异现象等特征，研究归纳出溧水爱景山锶矿床综合技术方法找矿模型，在所预测的远景区中，发现了锶矿。

According to logging results of 167 boreholes and chemical analyses of 24 369 samples as well as characteristics of element distribution at 4 000 m, 3 950 m and 3 900 m levels, the deposit is characterized by alteration, mineralization and element geochemistry of the porphyry. Alteration and mineralization are spatially and temporally related to the augen quartz phenocryst_bearing hornblendequartz diorite porphyrite (J3δομ).

根据167个勘探钻孔编录和化学分析（24369件化学分析样品）资料，以及对海拔4000 m、3950 m、3900 m水平面的Cu、Au、Ag、Mo、Mn、P b、Zn、W、K、Na、Ca、Rb元素分布规律的分析，显示矿体具有斑岩型矿床的蚀变、矿化以及元素地球化学特征，主要矿化和围岩蚀变在时间上和空间上均与含眼球状石英斑晶的角闪石英闪长玢岩（J3δομ）有关。

The RE E patterns of apatites in porphyrite iron deposits are in general similar to those of apatites in anorthosite, norite andjacupirangite . The apatites are enriched in light REE, with pronounced negative Eu anomaly.

结果表明产地和母岩不同的矿床中，它们的磷灰石稀土元素分布型式一致，以轻稀土富集和Eu负异常明显为特征，属陆相岩浆成因。
