补充资料：阿拉伯台地
| 阿拉伯台地 Arabian Platform 西亚阿拉伯半岛主体部分。地跨沙特阿拉伯、也门、叙利亚、伊拉克、约旦5国。西起红海沿岸的希贾兹山脉，东至阿曼湾岸的哈杰尔山脉，北至叙利亚中央高地，南达亚丁湾岸的也门高地。面积250万平方千米以上。为古老平坦地台，核心部分位于沙特阿拉伯的内志高原。台地自寒武纪以来，几乎未受到褶皱变动，古地质时代的沉积岩层基本保持平整。台地面海拔1200～2500米，地势自西南向东北缓倾。第四纪大规模的断裂运动，造成大量岩浆喷出，致使台地西部被深厚的熔岩所覆盖。属热带荒漠气候，表面沙漠广布，河道干涸，仅在地下水抬升处有零星绿洲。较大沙漠有鲁卜哈利沙漠、内夫得沙漠、代赫纳沙漠等。 |
