In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

辽西的深源岩石包体也有三种结构类型：①具有原生粒状结构、残碎斑结构的幔源橄榄岩类岩石包体；②具有堆晶结构的辉石岩类包体；③具有变晶结构的麻粒岩和片麻岩类岩石包体。

Petrographic and REE and trace element geochemical studies of these rocks and Nd isotope analysis of amphibolite indicate that the protoliths of the Mengjiatun Formation complex are sandstone, mud-rich sandstone and island arc tholeiite.

对这些岩石的岩相学，稀土元素，微量元素地球化学的研究和斜长角闪岩Nd同位素的初步分析，表明孟家屯岩组的原岩建造为一套砂岩，富泥质砂岩和岛弧拉斑玄武岩组合。

Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclaseamphibolite in Nanling ultra poor magnetite, and the analysis of graphs of and (FeO+Fe2O3+TiO2)Al2O3MgO, combining the geological features of mining area and the ore body characteristics, the conclusion can be drawn as follows: the plagioclaseamphibolites including magnetite and the plagioclaseamphibolite in Nanling mining area are formed from the oceanic tholeiite with rich iron after the deteriorating, and their genesis types should be the ultrapoor iron deposit of weathered residual origin.

通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪岩化学成分的对比分析，结合矿区地质特征和矿体特征，对矿体进行n-n和w( FeO+Fe2O3+TiO2)-w(Al2O3)-w 图解分析，结果显示南岭矿区的含磁铁斜长角闪岩和斜长角闪岩是大洋富铁拉斑玄武岩经变质作用而形成的，矿床的成因类型为风化残积型超贫铁矿床。

Formation of augen fabrics is decided by the ductile deference between the porphyroblast and matrix in deformation rock.

长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。

The comparison of petrology, lithofacies, petro-geochemistry and tectonic environment of the rapakivi granite both from Qinling-Kunlun and world shows that the rapakivi granite has same or consistent characteristics: rapakivi structure, sub-aluminous, high-potassic, alkali-rich magma, two-peak magma assemblage and formed in post-collision environment. However, there are some certain differences in some geochemical index, forming age of magma, and geotectonic position of outcropping.
