The authors make an all-around and systematic study of the funda mental characteristics of Mesozoic-Cenozoic crustal development in the Changbai-Xingan region on the basis of the results of the previous researches and practical -work according to diwa(geodepression) theory.It is concluded that the crustal movement has been gradually increasing its intensity since the Iate Trias and up to the highest point in the middle-upper Jurassic. Under such geological condition of crustal movement a lot of arched fracture-type and block-type diwa basins were formed. Huge thick Cathysian formations (Molasse strata) with certain terrestrial flysch rhythm were deposited and lots of eruptive rock formations were intercalated in these basins.Great changes took place widely following the strike in these sedimentary formations. One of the chief forms of the crustal movement was the regional fractures which were very active and developed into deep fractures with fault-fold zones distributed widely. In the arched fracture-type and block-type basins there were often formed open bra chyanticlines. Along the deep fracture zones and their adjacent areas the intrusive basic and ultrabasic rocks are widespread. Meta-alkali granite was intruded intensely in fault-fold zones. Magmatism occurred in the sequence from acid to basic-ultrabasic(or alkaline) and abundant mineral deposits were formed.The authors hold that the features of the Mesozoic crustal deve lopment in this region are obviously different from those peculiar to the underlying geosynclinal and platform structral layers. Therefore, a diwa stage indepedent of the platform structural stage should be established, and the region at the present stage must be attributed to diwa regions other than platform ones.

本文根据陈国达教授创立的地洼理论,在前人研究成果及其工作实践的基础上,对长白—兴安地区中新生代地壳发展阶段的基本特征,进行了比较全面系统的研究。认为该区自晚三叠世以来,地壳运动在逐渐增加,直到晚侏罗至早白垩世达到最高潮。在这样地壳运动的地质条件,区内广泛形成有拱曲型和块断型的地洼盆地。在这些盆地中沉积了巨厚层的、具有一定陆相复理式韵律的华夏式建造,并夹杂着大量的火山喷发岩建造。这些沉积建造,普遍的沿走向发生较大的变化。地壳运动的主要形式之一,是区域断裂构造活动强烈,而且形成较为发育的深大断裂构造,断褶带分布广泛。在拱曲型和块断型的地洼盆地中,往往形成开阔的短轴褶皱构造。沿着深大断裂带及其附近,普遍有基性,超基性岩侵入,在断褶带内偏碱性花岗岩浆活动强烈。岩浆侵入活动的顺序,为从酸性岩浆向基性、超基性岩浆(或碱性岩浆)方向演化。并形成有丰富的矿产。 笔者认为该区中新生代地壳发展的特点,与下伏基底地槽和地台构造层所代表的发展阶段的特点具有明显区别。因此,应当将它从区内由地台构造层代表的发展阶段划分出来;它是,一个新的阶段——地洼发展阶段。其现阶段的区域大地构造性质,不应当归入地台区,而是属于地洼区。

This paper deals with distribution of the sedimentary facies and ore deposits of Hubei province which may be controlled by tectonic elements, especially by the growth faults in long period.The studied region includes three sedimentary enviroments, they are shelf marginal basin of northern Hubei, platform shelf region of central Hubei and the deep-water shelf of southern Hubei.These environments are graben-type basins, separated by two deep fracture zones and some vanadium and uranium, barite, phosphorite occur the northern and southern deep-water regions, along faults, however, in the central Hubei platform only layered phosphorite deposits occurred.The distribution of blackshale series of early Cambrian in China and even throughout the world are very broadly.The author believed that the paleoclimate of early Cambrian in the worldwide was humid, oxygen-poor, and rich in CO_2, subsequently numerous small shelly fossils replenish the biosphere, as well as the large amounts of meteoric dust fell in earths surface, all of which led to particular paleoclimare and paleogeography of early Cambrian, and to be formed significant black rock series.

There are five major tectonic systems in China, namely arc, EW, NS, NE, and NW systems, They constitute a main tectonic grain and control the formation and distribution of various large mineral deposits, and mineralized zones formed in various development periods in various parts of tectonic systems, This paper only considers the EW and NS systems and their control over mineralization,1. The south Tianshan-Yinshan EW tectonic system, It is composed of a series of EWtrending parallel folds and associated faults and controlling many large Fe, Cu, Pb, Zn deposits.2. The Qinling EW tectonic system, It is a EW-trending linear structural zone, including the west Qinling fold system and east Qinling of the Qinllng-Anhui geodome system. There are some large Pb, Zn, Hg, Sb, As deposits controlled by the middle Devonian mudstone, siliceous, carbonate, fine-grained detrital rocks and EW-trending linear structural zone.3. The Nanling EW tectonic system. It is mainly composed of Caledonian geosyncline structural layers, but from middle to late Mesozoic period on, the system entered into diwa (geodepression) stage. Tectonic activities took place intensely. There are a lot of diwa granite-type and metasomatic-type W, Sn, Mo, Bi, Cu, Fb, Zn, and U deposits and many strata-bound Pb-Zn deposits, included in the upper and middle Devonian folded and faulted in diwa stage.4. The NS tectonic system in N-S diwa region. It is composed of N-trending lineaments, distributed as a zig-zag zone along east longitude between 102 and 106 degrees. In the system, igneous rocks especially basic and ultrabasic rocks and associated mineral deposits are well developed.5. The Hengduan Mrs NS tectonic system. It is in the west Yunnan diwa region composed of a series of NS-trending deep fracture zones. Several mineralization zones of Sn, Ca, Pb Zn endogenic deposits were formed as a result of magmatism, and a series of sandstone-type Pb-Zn, Hg and Sb deposits were formed in the Mesozoic-Cenozoic red beds.
