The characteristics of elements shows that magma of fine dioritequartz diorites derived from the enriched mantle or lower crust undergone ocean crust subducting and dehydrating, and was formed and emplaced in the process of crust growth. The magma of dioritic porphyritedacitic porphyries emplaced relatively late, it might derive from upper crust or undergo intensive contamination of crustal materials, and was formed in the proces of crust thining. These characteristics suggest that the geodynamics background of the Jinchanggouliang gold deposit formation is the transition process from compression to extension.

According to the variation in the components of intermediateacid igneous rocks coming from the lower crust, it is possible to restrain the depth of the source area and the minimum thickness of the crust, and thus to provide important information for the study of the deep process of the continental intraplate mineralizationGlobally, many world level porphyry copper deposits and metallogenic systems formed by hypabyssal hot liquid have their close relationship with the synchronous adakite in spacetime and genesis; domestically, the adakitelike rocks have been identified to be related to the metallogenesis in the main metallogenic areas in ChinaThe recognition of adakitelike rocks having no relationship with the process of subduction makes it possible to construct a metallogenic model of continental intraplate porphyry metal deposits by combining other geological evidences, and this model is totally different from the metallogenic model of porphyry copper deposits with Bsubduction setting constructed by Sillitoe (1972)The existence of adakitelike rocks may be the necessary condition but not the sufficient one for forming the largescale porphyry deposits and the hypabyssal hotliquid deposits, whose metallogenic elements mainly came from the mantleThe metallogenic potential of adakitelike rocks is achieved by the entering of the mantle material, and the metallogenic specialization of adakitelike rocks is decided by the distribution characteristics of the metallogenic elements in the upper mantleAn important reason for the adakitelike magma related to subduction being advantageous to mineralization is that there were abundant high pressure and high temperature liquid coming from the subducted platepieces and the magma of high fO2 coming from the melting of subducted platepiecesHowever, for those adakitelike rocks, whose occurrence has continental plate background but does not relate to the subduction, their metallogenic mechanism is not clear yetBased on the concept of modern mineral exploration and combined with the analysis of integrated geological information, we may better realize the practical prospecting significance of the adakitelike rocks

根据起源于下地壳的中酸性岩浆岩的成分变化，可以约束其源区深度以及地壳最小厚度，为大陆板内成矿作用的深部过程研究提供重要信息。全球范围内，许多世界级斑岩铜矿和浅成热液矿化系统与同期的埃达克质岩存在密切的时空与成因联系，在国内主要成矿区带也识别出与金属成矿作用有关的埃达克岩。与俯冲过程无关的埃达克质岩的识别，使我们有可能结合其他地质证据构建完全不同于Sillitoe(1972)B型俯冲环境的斑岩铜矿成矿模式的大陆板内斑岩型金属矿床成矿模式。对于规模巨大、矿质主要源自地幔的热液矿床的形成，埃达克岩可能是必要条件，但不是充分条件。埃达克岩的成矿潜力通过地幔物质加入而获取，埃达克岩的成矿专属性由上地幔成矿元素分布特征决定。与俯冲有关的埃达克质岩浆之所以有利于成矿，重要的原因是存在大量来自俯冲板片的高压、高温流体以及俯冲板片熔融形成高氧逸度(fO2)的熔体，但产出在大陆板内背景、与俯冲无关的埃达克岩的成矿机制还不清楚。根据现代资源勘查理念，结合综合地质信息分析，埃达克质岩具有实际找矿意义。

Comparing withHayek's theory on society method, I believe constitution litigationmechanism must considering the following conclusion in modelingconstitutional method: first, the acquiring of constitutional method isusually effects system vicissitudes. Although constitutional arbitramentcan form definite constitutional method, it can't achieve perduringsubstantial results level of method; secondly, constitutional method isformed virtually by the mixture of two kind of potence, and one is socialpotence, the other is governmental potence. The constitutional method'srationality in logic structure rests directly with the wrestling process ofconstitutional logic and social process. Constitutional method is more akind of simulative conformation of natural logic and social logic, itforms by the wrestling of government, public, legislature andconstitution judging organ. Fourthly, the maintenance of constitutionalmethod depends on the inner power sustained by faith and exteriorpower coming from the background of compulsion. Fifthly,constitutional method itself is a dynamic structure, and it's realizingquomodo and vindicating means is being in vicissitude, however, it canonly provide condition and inspiritment.

对照哈耶克的社会秩序理论，笔者认为，宪法诉讼机制在型构宪政秩序时必然要照顾到以下结论：其一，宪政秩序的取得，往往是一个制度自然变迁的结果，宪法裁决虽然也可能在短期内形成一定的宪法秩序，不过却无法强行地达到一个较大范围内持久的秩序实效水准；其二，宪政秩序实际上是由两种力量交合而成的，一是社会力量，一是政府力量，宪政秩序的逻辑结构的合理性直接取决于宪法逻辑和社会逻辑之间的博弈过程；其三，宪政秩序更多的是一种对自然逻辑和社会逻辑的模拟形态，是经由政府、公众、立法机关与宪法裁判机构的合作博弈而形成的，宪法诉讼的功用至多在于提供博弈规则，以实现纳什均衡；其四，宪政秩序的维护主要依靠来自信念支持的内部力量与来自强制背景的外部力量；其五，宪政秩序本身是一个动态的、常新的结构，其实现方式与维护手段也处于不断变迁之中，但无论如何，宪法诉讼机制所能提供的只是制约与激励两种。
