地洼学说自50年代提出后,发展很快,特别是近10年来,在理论上和应用上都有较显著突破.地洼学说理论的精髓,不仅在于提出了“地洼区”作为地壳构造演化的第三构造单元,而且强调了地壳构造动“定”递进演化的一般规律,这些见解,揭示了岩石圈构造演化的复杂性和构造单元的多样性.地洼区的分布,从时间上说,最近的研究表明:地 Diwa theory has been developed rapidly since its introduction in the 1950s, especially in the past 10 years, both in theory and in application. The essence of Diwa theory is not only that the “Diwa area” is proposed as the crustal structure Evolution of the third tectonic unit, but also emphasizes the general law of progressive evolution of the crustal tectonics “set”, these insights reveal the complexity of lithospheric tectonic evolution and the diversity of tectonic units.The distribution of dimpo regions, from the time On the said, recent studies have shown that:
