This thesis puts forward and discusses many problems about tectono -magmatism during Indo-Chinese epoch (T-J1,250 ~ 185Ma), Early Yanshanian (J2-J3,185 ~ 140Ma), Middle Yanshanian (K,,140 ~ 100Ma), Late Yanshanian (K2, 100 ~ 70Ma), and Himalayan epoch (E, N and Q, 70Ma ~ present), and emphasizes important spatial and temporal variation in the different type of magmatic rocks in relation to the evolution of the active continental margin of East China. It was long thought that the late Yanshannian epoch is the transition period from trench-arc system (Andes-type active continental margin) to trench-arc-marginal sea system (Western Pacific-type). A general decline in the intensity of volcanism related to the A -type and B -type subduction, and widespread tensional red basins throughout the east continent, and alkaline granites belt stretched along the coast some 2000km are the good marks for this transition period. During the Cenozoic era calc-alkaline andesite -ryolite, transformation -type and syntexis -type granitoids became extinct, but alkaline, high-almina basalts were widespread in the continental margin. With time, the marginal seas have widened and deepened, and led to development of oceanic basalt. The calc -alkaline volcanic rocks and syntexis-type granitoids related to B-type subduction migrated to the island -arc.

文章提出和讨论许多有关中、新生代各个时期,如印支期(T—J;,250—185Ma)、燕山早期八一L,185~NOM幻、燕山中期(民,10~tX)MtX)M劝、燕山晚期(氏,!m~刀M的和喜马拉雅期o----m一Q 7()M~现在)的构造一岩浆作用问题,强调不同类型岩浆岩如改造型花岗岩、同熔型花岗岩类、碱性花岗岩、钙碱性安山一流纹岩系、碱性火山岩以及不同类型的玄武岩与中国东部活动大陆边缘演化之间的重要的时间和空间变化的联系.经长期考虑,认为燕山晚期中国东部是沟一弧体系(安第斯型)向沟一弧一边缘海体系(西太平洋式)转化的过渡时期.与A型和B型俯冲有联系的火山作用在总体上的减弱、拉伸红盆在整个中国东部大陆的广泛分布以及沿海岸延伸长达ZMm左右的碱性花岗岩带的形成是这一过渡时期的良好标志.在新生代,钙碱性安山一流纹岩系、改造型花岗岩和同熔型花岗岩的消亡,碱性、高铝质玄武岩在大陆边缘的广泛分布,以及拉伸盆地发生加深和加宽;边缘海随着时间不断加深和加宽,并导致大洋玄武岩的发育;与B型俯冲有联系的钙碱性火山岩和同熔型花岗岩类迁移到岛弧地带.

This paper deals with the relationships between plate tectonics and magmatism and the transition of the Cordillera-type margin into Western Paicfic-type active continental margin of East China in Mesozoic and Cenozoic.In the Indo-Chinese cycle(T-J,250~185Ma) the two gigantic plates,initial Eurasian and paleo-Pacific plate,began their intense compression and subduction,which led to the formation of eclogite belts,regional metamorphism,orogeny,and many transformation-type granitoids and small amount syntexis-type...

This paper deals with the relationships between plate tectonics and magmatism and the transition of the Cordillera-type margin into Western Paicfic-type active continental margin of East China in Mesozoic and Cenozoic.In the Indo-Chinese cycle(T-J,250~185Ma) the two gigantic plates,initial Eurasian and paleo-Pacific plate,began their intense compression and subduction,which led to the formation of eclogite belts,regional metamorphism,orogeny,and many transformation-type granitoids and small amount syntexis-type granitoids without important volcanism.In the Early Yanshanian Period (J2-3,185~140Ma) further subductian between the initial Eurasian plate and paleo-Pacific plate brought East China gradually on active continental margin.Many transfomation-type granitoids,moderate amount of syntexis-type granitoids and volcanic rocks related to A-type and B-type subduction of plates,slabs and terranes were formed during this period.In the Middie Yanshanian period(K2,140~100Ma) the East China was situatedon a cordillera-type active continental margin.At the beginning of this period(140Ma) andesiterhyolite and some shoshonite volcanism and granitoid-diorite magmatism reached their peak.The Late Yanshanian period(K1,100~70Ma) represents the beginning of the transition period from the Cordillera-type(trench-arc system) to the western Pacific active continental margin(trench-arc-backarc basin system).At the East Conment of China andesiterhyolite volcanism, transformation-type and syntexis-type granitoid intrusion gradually extincted. Weakly-alkaline and alkaline volcanic rocks, alkaline granite and syenite with nonorogenic characteristics were formed along the deep fault zones. All of these magmatic rocks were vanished at the end of the Late Cretaceous.Many intercontinental basins formed in tension setting filled with red beds were distributed widespreadely in East China.During the Cenozoic time (E, N, Q, 70Ma to present) almost all of the granitoids and intermediate-acid volcanic rocks were extincted at the east continent of China, but alkaline,high-alumia basalts were widespread in the same region.With time, especially in Miocene,the marginal seas such as Japan sea,Yellow sea,East China Sea and South China sea,widened and deepened.The cafe-alkaline volcanic robs and syntexis-type granitoids related to B-type subduction migrated to the island-arc,with some Premiocene stratigraphic terranes separated from the East Asia.The transit of Cordillera-type to the western Pacific-type active continental margin were completed during the Cenozoic epoch.

本文论述中国东部中-新生代由科迪勒拉型转变为西太平洋活动大陆边缘过程中的构造-岩浆作用及其演化。在印支旋回(250~185Ma),初始欧亚板块与古太平洋板块强烈挤压俯冲,并伴随大范围改造型花岗岩类的发育。在燕山早期(185~140Ma),继续俯冲,改造型花岗岩进一步发育,并开始有同熔型花岗岩类的形成。在约140Ma两类花岗岩的形成达到高潮。在140~100Ma广泛发育安山-流纹岩系。燕山晚期(100~70Ma)由于弧后扩张,配合红色盆地的广泛形成,发育碱性火山岩和碱性花岗岩带.新生代中国东部大陆花岗岩和中-酸性火山岩活动消失,代之以玄武岩活动;边缘海和岛弧逐渐形成,钙碱性火山岩系转入岛弧地带。

Relations between ultrahigh-pressure metamorphosed belt and 3-D S wave velocity structure image in the upper mantle in the east continent of China were analyzed in present study. The results suggest that the velocity beneath the North China block is generally higher than that beneath the Yangtze block at 150 km depth. A velocity variation boundary belt appears beneath the Dabie-Sulu orogeny belt. Velocity values beneath Sulu region and the Shandong peninsula are in the identical contour line with that...

Relations between ultrahigh-pressure metamorphosed belt and 3-D S wave velocity structure image in the upper mantle in the east continent of China were analyzed in present study. The results suggest that the velocity beneath the North China block is generally higher than that beneath the Yangtze block at 150 km depth. A velocity variation boundary belt appears beneath the Dabie-Sulu orogeny belt. Velocity values beneath Sulu region and the Shandong peninsula are in the identical contour line with that beneath the Dabie orogeny belt. In the vertical velocity structure profile crossing the Dabie mountain along near N-S direction, at the region shallower than 100 km depth, the velocities beneath the North China and the Yangtze blocks are lightly less than the average value. The velocity distributions beneath the Yangtze block at the region deeper than 100 km, however, quite differ from that beneath the North China block. The velocity beneath the Yangtze block is slower than that beneath North China block. A anomalous velocity zone lightly less than zero at the south side of velocity variation boundary beneath Dabie mountain thrusts downward greater than 300 km depth beneath the North China block from south to north, at dip angle of about 30 degrees. A near zero velocity zone north of the velocity boundary seems to thrust upward the surface of the Yangtze block from 100 km depth along the N-S direction beneath the North China block. Such geometries of the velocity structure images beneath the region crossing the Dabie orogeny belt imply that the zones thrusting down and upward might be related to the evidences of the "traces" for the subduction and exhumation process of ultrahigh-pressure metamorphosed belt beneath the Dabie mountain.

本文分析了中国东部的上地幔剪切波速度结构及其与超高压变质岩带之间关系的构造意义。结果表明,在华北块体下面150km深处的速度高于扬子块体的速度值。大别-苏鲁造山构造带下面存在着一条地震波速度变化带。苏鲁、山东半岛下面的速度分布与大别造山带下面的速度分布处于同一个速度等值区域上。横跨大别造山带的南北走向速度结构剖面上,在100km以上的地壳和上地幔区域,华北块体下与扬子块体下面的速度均略低平均值。100km以下,大别造山带南北两侧的扬子与华北块体下面的速度结构分布形态大相径庭。华北下面的波速高于扬子块体下面的波速。大别造山带下呈现速度异常,界线的南侧,有一个略低于零速度的负波速异常区,呈现由南向华北块体的下方斜冲形态,下冲角度大约为30°,其先端部位下冲深达300多公里,其外围零速度等值线的分布区,斜向下延伸超过400km。在速度结构变化分界线的北侧,一个零速度值的分布区带,呈现出从由100多公里深处从北向南朝地表面斜上冲形态。这些速度结构成像的几何形态可能意味着200Ma前大别超高压变质岩带的形成与演化的俯冲、折返的构造运动在上地幔和岩石圈中留下的“痕迹”。
