查尔斯王子山主要由太古代至晚元古代的变质杂岩组成,局部地区有寒武纪花岗岩侵入,并且被一小块晚二叠世沉积地层不整合覆盖。变质等级界子绿片岩相和麻粒岩相之间。尽管由于晚期变质作用的叠加使地质特征、变质特征和同位素特征更为复杂,但至少可以鉴别出两期主要的变质作用——一期发生于太古代,另一期发生于晚元古代。地质年代学研究获得的87Sr/36Sr初始比值的变化范围很宽,被解释为这两期主变质作用中包括有地壳形成和再造过程的证据。 太古代岩石出露在南查尔斯王子山,由一年代为2800百万年的花岗质基底杂岩组成,其上不整合覆盖着变质沉积岩层,该变质沉积岩层以醒目的白色含铬云母石英岩为特征,石英岩在一处被一条年龄为2580百万年的白云母伟晶岩切割。区内的条带状含铁建造也可能也属于太古代。这些太古代岩石被时代可能属于中元古代的拉斑玄武质基性岩脉侵入,其上覆盖着局部扭曲的晚元古代绿片岩相变质岩层。南查尔斯王子山的绿片岩相变质作用被认为是主变质幕的一个边缘相带,这期主变质幕发生于800至1100百万年之间,在北查尔斯王子山生成了角闪岩相和麻粒岩相变质岩。大约在500百万年以前,花岗质岩株和伟晶岩侵入于前寒武纪岩石之中,与这些侵入岩体有关的一期热作用重新调整了矿物的同位素体系。几个交切基底的显生宙碱性基性侵入岩被认为与沿主断裂构造发生的活动有关,目前兰伯特冰川——埃默里陆缘冰占据了这一构造位置。 查尔斯王子山可能提供了东部南极洲变质地盾最好的横剖面,它也是南极洲至今确定的唯一的太古代克拉通地块。与冈瓦纳古陆其它地区的比较揭示了该地区与非洲和西南澳大利亚有许多相似之处,但是与印度半岛,斯里兰卡没有多少相关性,通常认为,这些地区在冈瓦纳泛大陆中与查尔斯王子山是拼合在一起的。本文进行的研究还论证得出了一个结论,即一个地区变质程度最高的岩石不一定是最古老的岩石。在东部南极地盾的研究中,对地质年代学的重要性给予了充分的重视。
The Prince Charles mountain consists mainly of Archean to late Proterozoic metamorphic complexes, with Cambrian granite intrusions in some areas and unconsolidated by a small block of Late Permian sedimentary strata. Metamorphic grade boundary between greenschist facies and granulite facies. Although the geological, metamorphic and isotopic characteristics are more complicated due to the superimposition of late metamorphism, at least two major metamorphisms can be identified - one in the Archean and the other in the Late Proterozoic. The initial 87Sr / 36Sr ratios obtained by the geochronology study vary widely, and are interpreted as evidence of the crustal formation and reconstruction processes in both phases. Archean rocks are exposed in Prince Charles South, consisting of 2800 million years of granite basement complex, unconformably overlain with metamorphic sedimentary formations that have striking white, chrome-mica-quartz Rock is characterized by the quartzite being cut at one site by a muscovite pebite aged 2580 million years old. The formation of banded iron in the area may also belong to the Archean. These Archean rocks were invaded by the Mesoproterozoic tholei basaltic dykes dating back to the age and covered with locally distorted Late Proterozoite metamorphic metamorphic strata. The greenstone facies metamorphism of Prince Charles South is considered to be an edge facies belt of the main metamorphic curtain that occurred between 800 and 1100 million years ago. Amphibolite facies were formed in the North Prince Charles Mountain Granulite facies metamorphic rocks. About 500 million years ago, granitoids and pegmatites intruded into Precambrian rocks, and the thermal phase associated with these intrusive rocks readjusted the mineral isotopic system. Several bedrock basaltic alkali-based intrusive rocks are thought to be associated with activities that occur along the main faulted structures, and the current Lambert Glacier-Emory rift ice occupies this tectonic setting. The Prince Charles may offer the best cross-section of the metamorphosed shield of the eastern Antarctic, and it is also the only Archean craton that Antarctica has so far identified. Comparisons with other parts of the Gondwanaland show that the area has many similarities with Africa and South-West Australia, but with little relevance to the Indian Peninsula and Sri Lanka, and it is generally accepted that these areas are associated with Charles in the Gondwana Prince Hill is put together. The research conducted in this paper also argues that the rock with the highest degree of metamorphism in a region is not necessarily the oldest rock. In the study of the eastern Antarctic Shield, great importance has been attached to the importance of geochronology.
