3花岗岩中云母含量的变化对花岗岩宏观峰值强度的影响虽然不是非常显著，但是，从细观角度考虑，其影响的幅度还是需要引起注意的，在云母含量在大约5%时，花岗岩的峰值强度最高。

It has been shown in the Al(Na+K+Ca/2) diagram that the Jinla granitoids are all plotted within the area of "S" type of granites, but the samples from Laochang amphibole admellite, Menglinshan biotite admellite and Nanla K-feldspar graniteporphyry are scattered gradually far away from the boundary between "I" and "S" types of granites, implying that the components from the upper mantle gradually decreasing from the Laochang amphibole admellite to the Menglinshan biotite admellite and then to the Nanla K-feldspar granite porphyry.

3上述三类花岗岩样品皆位于S型花岗岩区，但从老厂似斑状角闪二长花岗岩，勐林山似斑状黑云二长花岗岩，到南腊碱长花岗斑岩，样品分布逐渐远离"I"型花岗岩和"S"型花岗岩的分界线，这表明自老厂似斑状角闪二长花岗岩至勐林山似斑状黑云二长花岗岩，到南腊碱长花岗斑岩幔源组分逐渐减少。

Petrochemistry, trace element, REE and isotope geochemistry of quartz syenite porphyry, quartz diorite porphyry, rhyolite, and biotite granite indicate that they belong to series Ⅱ granite defined by Wangliankui (l972), but they have some characteristics of series Igranite, which shows adding of recycle upper-crust materials.

岩浆岩岩石化学、微量元素、稀土元素及同位素地球化学特征表明，莲花山矿区的石英正长斑岩、石英闪长玢岩、流纹岩和黑云母花岗岩属于王联魁(1972)所划分的系列Ⅱ花岗岩(相当于Ⅰ型磁铁矿系列花岗岩)，但也具有系列Ⅰ花岗岩的某些地球化学特征，表明岩浆中有再循环上地壳物质的加入。

Xitian granitic multiple intrusion dominately consist of medium-fine porphyritic biotite granite, with complementary fine biotite granite with much lesser phenocrysts and deuteric injections.

该复式花岗岩可划分为主体（中细粒斑状黑云母花岗岩）、补体和晚期侵入体。

On the basis of the rock type, texture and structure and formations age of the Kuiqi miarolitic granite batholith it is devided into 4 units:1 Miarolitic biotite-feldspar granite; 2 Medium-coase-grained miorolitic alkali-granite ; 3 Porphyritic miarolitic alkali-granite ; 4 Fine-grainedmiarolitic alkali-granite .

根据魁岐杂岩体的岩石类型、结构构造、形成的时间先后等，将其划分为4个单元：(1)晶洞黑云母钾长花岗岩；(2)晶洞中粗粒碱性花岗岩；(3)晶洞斑状碱性花岗岩；(4)晶洞细粒碱性花岗岩。

Based on studies of petrology, petrochemistry and REE geochemistry of the Muluozhai REE ore de- posit in Sichuan and the granite related to REE mineralization,it is known that the granite is nordmarkite in- stead of previously-considered biotite granite.

通过对四川木落寨稀土矿床及与成矿有关的花岗岩的岩石特征、岩石化学以及稀土元素地球化学研究表明，与成矿有关的岩石是英碱正长岩，而不是前人认为的黑云母花岗岩。

Geochemical characteristics indicate S-type granites and volcanic rocks depleted in sodium and enriched in potassium, with 62.42%～78.02% w(SiO2), 7.66%～9.13% w(K2O+Na2O), 1.18～2.62 w(K2O)/w(Na2O), and Rittmann index δ of 1.67～3.78. They are enriched in LREE with an average LREE/HREE ratio of 10.94×10-6, and generally depleted Eu with an minimum δEu less than 0.31 especially in the ignimbrite and biotite granite, which have experienced a significant process of separation and crystallization of plagioclases.ΣREE at the main stage of the magmatic activity decreases with time.
