The theory of activated or geodepression( Diwa in Chinese words) 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 a new-type continental mobile region of postplatform stage and differing from a geosynclinal region. 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 crustal bodies,hypothesis of mantle creep-flow and geothermal energy coacervation-diffusion alternation, tectonogechemistry and metallogenic tectonics.
Diwa theory belongs to the category of historism-causationism geotectonics advanced by the author. Its developmental programme is as follows:(1)To use the historic-dynamic synthetical analysis research methods. (2)To implement the academic line of paying attention to both theory and practice as well as fitting in with the needs of production. (3)To act along the way of strengthening the inner core and adjusting some of the protective spheres. (4)To follow the principle of self-perfection combining with emulating others 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) Theoretic studies of the Diwa region itself, such as the criteria for its determination, its type-classification, its ages, its distributions,its crustal movements,etc.(2)Practical studies by using the concept of Diwa region,such as in regional geology, metallogenic regularities and prognosis for ore, geotherm,hydrogeology,geomorphology,neotectonics, etc.
