Meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff; in the tufaceous mud, the thermal fluid activity accelerates "maturating" of the organic carbon by heating; and the trace elements show an anomaly in the wall rocks.

同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的"催熟"加热作用，微量元素则出现异常现象。

1St, foreword main point: A, about Earth's internal heat circulation as well as successional variation process three important times: Birth time, lifeless time, until has the life time; B, the earth interior stone fruits archery target thermonuclear reaction, causes the earth interior material convection and the Earth revolve production as well as terrestrial magnetic field production three between relations; C, also has in has the life time, the vital activity to the entire internal heat circulation influence as well as to the earth's atmosphere influence; D, has the life time, in the stratum the coal and the petroleum, the natural gas and so on the fixed energy storage which as a result of energies and so on zoology and botany absorption transformation sunlight forms, to Earth internal heat circulation influence as well as with earth's crust each kind of movement relation, such as: The plate movement, the volcanic earthquake, the orogenesis, the Earth moves the fierce degree the periodic phenomenon and so on.

前言要点： A 、关于地球的内热循环以及演变过程的三个重要时期：诞生时期，无生命时期，直至有生命时期； B 、地球内部核物质的热核反应，引起的地球内部物质对流与地球旋转的产生以及地球磁场的产生三者之间的关系； C 、还有在有生命时期，生命活动对整个内热循环的影响以及对地球大气的影响； D 、有生命时期，地层中煤与石油、天然气等由于动植物吸收转化太阳光等能量而形成的固定能量存储，对地球内热循环的影响以及与地壳各种运动的联系，诸如：板块运动，火山地震，造山运动，地球活动剧烈程度的周期性现象等。
