Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.
结合已有的研究资料可以认为,黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质,浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质;含铁建造形成于陆壳基底之上,形成时间约2.7 Ga,并于2.5—2.7 Ga之间发生首次变质作用。

We analyzed the tectonic differences and deep geodynamic characteristics based on the tomographic results, which show high velocity anomalies at the uppermost mantle beneath the northeast SCS, and depict the lithospheric mantle extension from South China continent to marginal sea. Because of the low temperature and thick lithosphere beneath the northeast SCS, it seems no magma intruded from mantle, so we inferred that the rift may only occur in the crust rather than extend to the upper mantle, which shows the nature of nonvolcanic continental margin.
结果表明:南海东北部表现出陆架地区的岩石层特性,属于华南大陆向海区的延伸,岩石层厚度较大,现今不存在大规模的地幔热流活动,推测大陆边缘张裂作用仅限于地壳内部而没有延伸进入上地幔,具有非火山型大陆边缘的深部特点。

When the shockwave energy weakened, mountain collapse often occurs in the ringed mountain, particularly in the previously steeper inside, while plagioclase slope slide (primary meteorite-stricken slope slide) occurs in the outside mountain, and the mountain structure is constantly adjusted in aftershocks to achieve the gravity balance; during the long geological ages after the formation of meteorite crater, under the action of erosive transit and dryness and humidity of hydrosphere and air current, volcano and earthquake activities, etc., the physiognomy gradually reverts to the original state.
在冲击波能量减弱时,环形山原来较陡峭的内侧多发生山体崩塌,外侧山体发生斜岩滑坡,在余震中山体构造不断调整以达到重力平衡;在漫长的地质年代里,陨击坑成型以后,在水圈、大气环流的侵蚀搬运、寒暑燥湿、火山和地震等因素作用下地貌逐步趋于还原。
