2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.
深入剖析:地球可以说是一个非常奇妙的热核反应堆,当地球内部的压力达到一定的临界,地球物质中可衰变的核物质统称为热核物质,就会发生热核反应,从而产生巨大的能量,进而融化部分物质,形成岩浆即液态物质,这个反应层面可能是多个层面,第一层可能位于地壳与地幔之间,向上下两边对流,表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象;第二层可能位于下地幔与地核之间,压力更为强大,引起不易发生热核反应的热核物质发生反应,形成相对比较稳定的液化物质层,同时向上下两边对流,形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象;这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。

Analyzing the relation between earthquake and structure distortion, main fault belt, crust, upper mantle, ground fracture, hotspring, geotherm, conductance frame, stress state in Guanzhong area is analyzed with earthquake mechanism, isoseismal line, crustal stress measure, fault displacement measure, and simulating test results. Earthquake formation mechanism is discussed with dynamics mechanism in Guanzhong base. There are 3 forces and a good medium environment, which are main reasons caused earthquake happened in Guanzhong area. The first force is NE and NEE level extrusion one which is parallel with long axis of Guanzhong base. The second one is level strain which is vertical with long axis of the base.
对地震与构造形变、主要断裂带、地壳及上地幔、地裂缝、温泉和地热、电性结构等关系进行了分析研究,通过震源机制解、地震等烈度线、地应力测量、断层位移测量及模拟试验等成果,分析了关中地区的地应力状态,从关中盆地的动力学机制,对该区的地震成因机制进行了探讨,认为与关中盆地长轴平行的NE和NEE向的水平挤压力、与盆地长轴方向垂直的水平张力及地幔上涌力三组力的作用,加之壳内高导层这一有利的介质环境,是导致关中地区地震发生的主要原因。

The early stage of me tamorphism happened before deformation in the upper mantle at about 60-70km. Then metagabbro emplaced rapidly at about 40 km by diapirism and perhaps amalgamated with cool subducted oceanic crust. After that, rapid cooling retrograde metam orphism occurred. Early rapid ocean spreading was constrained because subduction appeared. Therefore, metagabbro continued to uplift under the slow extension. At last, it obducted and thrusted to outcrop on the surface.
变形前的早期变质可能发生在60~70km处的上地幔,然后变质辉长岩快速"底辟"构造侵位,上升至约40km深处,可能与俯冲的冷洋壳并置,发生快速降温退变反应;因俯冲作用的开始,抑制了洋盆快速扩张,变质辉长岩在减速伸展环境下继续抬升减压;后期又由于仰冲推覆,最终出露地表。

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.
稀土、稀有元素主要富集于灰黑色粗面岩中,而在其他岩石类型中相对较少,同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用;提出了本区的碱性岩组合具有次火山岩相的特征,讨论了本区碱性岩的成因,认为其与湖北庙垭地区的碱性岩可能均来自上地幔,并不同程度地混染了大陆壳的物质成分,其形成时代与断裂构造带的发生、发展和演化基本同步。
