Geological field study tour

Geological field study tour

 

On 5th May 2019, our scout members visited Ma Shi Chau to conduct a geological field study tour. Despite the drizzle on the day, under the guidance of the guides from the Tai Po Geological Education Centre, we successfully conducted our study. During the study, the characteristics, formation and erosion of different types of sedimentary rocks were introduced by the guides. Our members could even touch the iconic sedimentary rocks of Ma Shi Chau, the colorful mudstone. In addition, we learned a lot of knowledge about hydrology, plants and humanities, such as the impact of the nearby geology on the water quality, the occurrence of plants there (such as Kandelia and Pandanus tectorius). The most excited moment was that we saw a lot of sea cucumbers on the beach during the low tide and this marked a wonderful end to our study.

 

地質公園考察活動

 

本旅成員於2019年5月5日到訪了馬屎洲進行地質章考察活動。當天雖然下著細雨,但在兩位大埔地質教育中心的導賞員帶領下,亦無阻我們考察。期間介紹了有關不同種類沉積岩的特質、形成方法、侵蝕,也親手摸了馬屎洲的標誌性沉積岩- 七彩泥岩。此外他們也為我們介紹了不少有關水文、植物、人文的知識,例如附近地質對馬屎洲一帶的水質影響、馬屎洲生長的植物如秋茄、露兜等等。最令我們興奮的是正值潮退,我們在灘上見到了為數不少的海參,為我們的考察畫上了精彩的句號。
