A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

构造力可以分解为两部分一部分是均应力，指各向相等的应力，它叠加在原有压力之上，并且影响着各种化学反应的平衡，也是成岩、成矿和变质作用的影响因素。

Then the PTt-D paths in different places have been constructed and compared with those of the typical low-pressure and mid-pressure metamorphism both within China and abroad. Based on their similarities and differences and combined with the study on the characteristics and petrogenesis of granitic rocks, the protolith of metamorphic rocks and their tectonic significance, the tectonic setting and the geodynamic mechanism that caused the metamo rphism.

据此构筑各地区的PTt-D轨迹，并与国内外一些典型低压和中压变质地区相对比，分析彼此的共性和特性，再结合花岗质岩浆作用的特征及成因，以及原岩建造及其所代表的大地构造环境等方面的资料综合分析，以确定本区当时的大地构造环境和引起这种样式变质作用的地球动力学机理。

And positive anomaly of Rb,Ba,Sr,etc. The granite emplaced by underplating of granitic magma,which formed through partial melting of sedimentary mainly of arenite,and is typical crust source petrogenesis.

岩体是以杂砂岩成分为主的沉积岩部分熔融形成的花岗质岩浆上升侵位过程中形成的，是一种典型的壳源成因类型。

The relatively high Sr/Y (~ 40) and low HREE (Yb.8 ppm) suggest that garnet may play an important role, either as restite or as a fractionated phase, during petrogenesis of the rock.

其较高的Sr/Y（~ 40）和低的重稀土（Yb.8 ppm）反映在其形成过程有石榴石的残留或分离结晶。

The first method is not related to petrogenesis, but welcomed by its benefit in field work and basic petrology research; the second method reflects magma sources and tectonic environment, which has always been considered to be very important since proposed, especially a steady flow of A-type granite result in recent years; the third method, often used by researchers, consists of information about mineralogy, petology and magma source; the last method is characterized for its simple and uniform classification criterion, as well as strong operability.

矿物学－岩石学分类不涉及成因信息，比较适用于野外工作以及最基本的岩石学研究；ISMA分类的标准反映的是岩浆源区和构造环境，自提出后备受重视，尤其是A型花岗岩的研究成果近来大量涌现；Barbarin的综合性分类包含了矿物学、岩石学和岩浆源区的信息，也受到一定的推崇；Frost的地球化学分类标准统一，具有很强的操作性。

On the basis of a large number of actual data of a series of characteristics of the forming process of granitoids of different ages associated with endogenic metallogenesis in Jiangxi and the Nanling region,the forming process of granitoid and the perfect course of its ore-forming continuous evolution have been expounded and proved.On this basis,the perfect conception of the forming process of modern granitoids including magmatic genration, magmatism and petrogenesis, and magmatic hydrothermalism and metallogenesis has been suggested.

以江西及南岭地区不同时代花岗岩类形成过程的一系列特征及其与内生金属成矿作用的关系等方面大量的实际资料为依据，论证了花岗岩类形成作用及其成矿连续演化的完整过程；进而提出现代花岗岩类形成作用的完整概念包括岩浆的发生，岩浆的作用与成岩，以及岩浆热液的活动与成矿三个部分。
