你好,我们走在多尼哥县Bundoran爱尔兰今天和我们遇到的地质特性所示图片(从上方悬崖和在海滩很近)。我们有三个问题呢?1。你怎么叫它?在我看来高高的岩石上双方是海栈但不是中间的侵蚀一点更像是海树桩吗?或者他们是完全不同的东西吗?2。它是什么类型的岩石(特写照片)我们猜是页岩,但它也可能是石灰石。你觉得是哪一个?3所示。 Please notice the ubiquitous fossils in the close-ups. Are we correct to think they are crinoids? I have just realised a good view from top of this feature is available on Google, so I am sharing it here as well: https://www.google.com/maps/@54.4852881,-8.2823865,3a,75y,49.15h,69.55t/data=!3m8!1e1!3m6!1sAF1QipNS26PrjyPwTfKnxdxVE29LHtp7A8TctpDVSjl1!2e10!3e11!6shttps:%2F%2Flh5.googleusercontent.com%2Fp%2FAF1QipNS26PrjyPwTfKnxdxVE29LHtp7A8TctpDVSjl1%3Dw203-h100-k-no-pi-0-ya103.88327-ro-0-fo100!7i8192!8i4096 Than you in advance for answering all our questions.
