地洼学说的理论结构和发展纲领

地洼学说(活化区理论)自1956年诞生以来,经受过35年的检验,已发展成为5个组成部分和2个衍生学科的理论体系。它的理论结构是以第一个组成部分,即大陆地壳中发生于地台阶段之后、特征与地槽区不同的一种新型活动区——活化区即地洼区概念为内核。保护层为其余的组成部分和衍生学科,即地壳动定转化递进说。递进(地洼)成矿理论、壳体概念和地幔蠕动热能聚散交替假说,以及构造地球化学和成矿构造学。 地洼学说是属于作者倡议建立的“历史—因果论大地构造学”范畴。它的发展纲领应是运用“历史—动力综合分析法”的研究方法;贯彻理论实践并重和切合生产需要的学术路线;采用充实和加固内核以及调整某些保护层的方式;按照自我完善与学百家之长相结合的原则,研究领域包括学说本身的进一步发展和运用它以解决实际问题。 内核的充实和加固包括两个方面:(1)理论方面的研究,例如地洼区的鉴别依据、类型划分、形成时代、分布地区、地壳运动等方面的问题。(2)实用方面的研究,例如用于区域地质、地貌、新构造、地震等方面的问题。 关于保护层的加强和扩大,主要有如下的工作:(1)地壳动定转化递进说——在理论方面为适用范围的检验,地壳发展按照动定转化规律的原因、超越发展阶段问题、可逆发展问题及哲学思维方法等的?

THEORETIC CONSTRUCTION AND DEVELOPMENTAL PROGRAMME OF THE THEORY OF ACTIVATED (GEODEPRESSION OR DIWA )TECTONICS

The theory of activated or gcodepression (diwa in Chinese words) teetonics has developed and become a theoretic system which contains 5 component parts and 2 derivative disciplines since it was born in 1956 and has withstood the test by practice for 35 years. In its theoretic construction, the core is the concept of activated region (geodepression or diwa region) which is a new-type continental mobile region of postplatform stage and differing from a geosynclinal reglon. The protective spheres are the other component parts and the derivative disciplines, i. e. , theory of progression with transformation between mobile and stable regions, theory of progressive ore formation, concept of crustobodies, hypothesis of mantle creep-flow and geothermal energy coacervation-diffusion alternation, tectonogeochemistry and metallogenic tectonics.Iiwa theory belongs to the ca]tegory of historistic-causationist geotectonics advanced by the author. Its developmental programme is as follows: (1) To use the history-dynamic synthetical analysis research methods: (2) To implement the academic line of paying attention to both theory and practice as fitting in with the needs of production. (3) To act along the way of strengthening the core and adjusting some of the protective spheres. (4) To follow the principle of self-perfection combining with emulating other's strong points. (5) to further develop the theory itself as well as to solve real problems with it.To replenish and strengthen the core may be studied in two ways: ( 1 ) Theorotic studies of the diwa region itself, such as the criteria for its determination, its type-classification, its ages, its distribution, its crustal movements, etc. (2) Practical atudies by using the concept of diwa region, such as in regional geology, metallogenic regularlties and prognosis for ore, geothermy, hydrogeology, geomorphology, neotectonics, seismology, etc.As to the reinforcing and enlarging of the protective spheres, the following works are needed : ( 1 ) On the theory of progression——Theoretically, rescarches inchide: tests of its applicable scope, cause of crustal development with transformation between mobile and stable regions, probiem of bypassing of development stage, problem of reversible development, philosophic thinking methods, etc. Practically, it will be used to study history of regional tectonics, historical geology, paleogeography, relation of environment to paleontological evolution, time and space changing regularities of earthquakes, etc. (2) On theory of progressive ore formation——Mainly to study the metallogenic specialization of different tectonic elements, history of metallogenic development, polygenetic compound ore deposits, ore-controlling of deep-teated structures, mantie-crust compound ore deposits, regional metallogenic regularities and prognosis of ore, metallopnic charsct(?)ristic of certain ore areas, etc. (3) On the other protective spheres——To study the evolution and movements of crustobodies, the relation of mantle creep—flow to the evolution and movements of crustobodies and to the formation of related ore deopsits and structure, etc.Methods and ways for developing diwa theory mainly are : combination of historism and causationism, of historic and dynamic analyses, of development and connection viewpoints, of inductive and deductive methods: consideration giving to both substance and movement, to both crustal evolution and movements as well as their root causes and dynamic mechanism, to both time and space in three dimensions, to both horizontal and vertical movements, to both formations and deformations, etc.
