著名地质景点、自然奇观的白岩坍塌,分秒之间的沧海桑田
本帖最后由 人与自然 于 2012-3-17 13:18 编辑据英国《每日邮报》3月14日报道,英国东部港市多佛市的著名地质景点-多佛白岩近日因极端天气发生大面积坍塌,导致重约数千吨、面积相当于一个足球场的巨块石灰石掉进大海中,堆成一座小山。专家认为,坍塌是因为雨水流入干旱期裂开的石缝,在近期的严寒天气中结冰膨胀,导致这块巨石逐渐松动,最终与悬崖脱离。地质演变需要历经几万年直至上亿年,能够有幸看到著名地质公园瞬间的变迁,极其壮阔的跃动,让然留下深刻印象。
多佛白崖(The White Cliffs of Dover)http://en.wikipedia.org/wiki/The_White_Cliffs_of_Dover
位于英国英格兰,作为英格兰的象征,人们很难登上多佛白崖的最高点。这个约100万年前形成的悬崖由细粒石灰石组成。悬崖的最高点在海滩之顶(Beachy Head),那里的白垩层经过数百万年的沉积从下面的海滩中上升了500英尺(约152米)高。
多佛白崖位于北纬51°06'N,东经1°14'E,北纬51°12'N,东经1°24'E。白崖标志着英国接近欧洲大陆的最密切的多佛位置一点。在晴朗的日子,都是悬崖峭壁很容易地从法国海岸可见。
峭壁主要是白色白垩石组成,其他主要是钙板,板形成碳酸钙颗石藻,单细胞浮游 藻类的遗骸沉没到海洋的底部产生的,并连同仍然底部众生,形成沉积物。燧石和石英中还发现白垩石。多佛崖面继续以每年1厘米的平均增长,虽然偶尔大块将下降。这发生在2001年,当大块的边缘,如一个足球场大,进入下跌通道。进一步大段倒塌到2012年3月15日英语频道。游客,因此,呼吁继续从悬崖边走。
在2005年的Radio Times的读者调查,多佛白崖被命名为英国第三大的自然奇观。
