澎湖群島的美麗與憂愁 (The Beauties and Worries of Penghu Islands) - 顏一勤地質技師主講 (I-Chin Yen)

這是香港地質學會主辦，由顏一勤地質技師在2022年5月14日香港時間下午2時主講的網上講座的實時錄影。 This is the live recording of the webinar organized by the Geological Society of Hong Kong held on 14th May 2022 at 2:00 p.m. Hong Kong Time. The webinar was given by Mr. I-Chin YEN. PowerPoint 的 pdf 文檔可在 www.adv-technovation.com/free-youtube-videos 下載。 位於台灣海峽的澎湖群島，主要由中新世的沉積岩與玄武岩互層所構成。玄武岩流冷卻後形成的柱狀節理，隨著冷卻過程的條件差異，留下了千變萬化的柱狀節理形態。四面環海的島嶼環境，波浪作用也刻畫出多樣的海蝕地景。然而，隨著玄武岩本身的節理特性，加上外營力的侵蝕與風化作用，海岸邊緣的地質災害也正在孕育著。本文主要介紹澎湖群島的地質景觀特色，以及近年來地質公園的設立現況，並藉由近年的調查經驗淺談海岸環境的地質災害危機。 Penghu islands, located in Taiwan Strait, are mainly composed of interbeds of Miocene sedimentary rock and basalts. The landscapes of Penghu Islands were developed from the columnar joints formed during the cooling of basaltic lava flow and depiction of wave erosion. There are potential geo-hazards along the cliffs created by weathering and erosion relating to the joints of basalts. The geological landscapes and Geopark delineating Penghu Islands are introduced in this webinar. Moreover, the surveying experience of geo-hazards of these islands are also presented. 因應不同節目和觀眾需要，ATL 頻道將會以廣東話、國語和英語進行廣播，內容包括學術性的 (Academic)，技術性的 (Technical)，和趣味性的 (Leisure) 節目，包羅萬有，盡量滿足不同觀眾的興趣和口味，觀眾可就自己個人興趣去選擇不同類型節目，所有節目都在我們的網頁 https://www.adv-technovation.com/free... 分表列出，方便各位觀眾欣賞。請免費加入我們頻道，並歡迎留言或在電郵 [email protected] 聯絡我們，多謝支持!
