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。

First, mineral resourcesZhuhai's hidden stone for the main biotite granite, biotite-granite, granodiorite.

The geochemical characteristics indicate that biotite granodiorite is equivalent to cordierite-bearing peraluminous granitoids, while biotite granitoids are similar to muscovite-monzonitic granite.

地球化学特征表明，黑云母花岗闪长岩与含堇青石的过铝花岗岩相当，而黑云母花岗岩则类似于白云母二长花岗岩。

These results indicate that both the second type leucosome in the biotite gneisses and the first type leucosome were produced synchronously in the Paleoproterozoic granulite-facies metamorphism, and that both the melt-derived and the metamorphic Paleoproterozoic zircons suffered significant lead-loss in the Triaasic, suggesting that both felsic granulite and biotite gneisses be responses to the Triassic deep subduction event.

这表明，第二类浅色体和第一类浅色体都是古元古代麻粒岩相变质作用同期深熔产物。古元古代熔体结晶和变质结晶锆石在三迭纪发生了严重的放射性成因铅丢失，可反映长英质麻粒岩和黑云母片麻岩都响应了三迭纪深俯冲事件。

Furthermore,~(40)Ar/~(39)Ar and K-Ar ages of individual mineral indicate that for isotopic age measurement hornblende and biotite are analogously the ideal minerals, while for K-Ar technique hornblend is the best followeed by the biotite, and the feldspar age has to be used with great care.

40Ar/~(39)At和K-Ar年龄结果还表明：角闪石和黑云母均是~(40)Ar/~(39)Ar理想定年矿物，对K-Ar法而言，角闪石最理想，黑云母次之，长石年龄使用要慎重。

Humic acids may promote K releasing from K-bearing minerals such as vermiculite, biotite, muscovite, orthoclase et al. In which, the effect on biotite and vermiculite were stronger than muscovite and orthoclase.

同时，腐植酸可以促进蛭石、黑云母、白云母和正长石等含钾矿物钾素的释放，其中，对黑云母和蛭石中钾素释放的影响比白云母和正长石的大。

The low-pressure andalusite sequence metamorphic belt includes biotite zone, garnet zone, staurolite zone, staurolite-andalusite zone, sillimanite zone and cordierite-sillimanite zone. It is calculated that the P-T conditions are 445～550℃, 0.2～0.6GPa for biotite zone, 480～566℃, 0.54± 0.22GPa for the garnet zone, 601±20℃, 0.8±0.25GPa for the staurolite zone, 540±20℃, 0.32± 0.05GPa for the staurolite-andalusite zone, 640℃, 0.43GPa for sillimanite zone, 740～800℃, 0.4～0.7GPa for the cordierite-sillimanite zone.

黑云母带的变质条件估计在445～550℃、压力在0.2～0.6GPa范围变化；石榴石带温度在480～566℃、压力在0.54±0.22GPa的范围；十字石带范围为601±20℃、0.8±0.25GPa；十字石-红柱石带为540±20℃、0.32±0.05GPa，而利632.4℃、0.785GPa，这个值不是红柱石的稳定范围，这可能是其早期中压变质条件；矽线石带的条件640℃、0.43GPa左右，由于其石榴石中有蓝晶石包体，因此其早期也可能有中压条件的变质；堇青石-夕线石带范围大致为740～800℃、0.4～0.7GPa之间。
