該島由香港最古老的沉積岩組成，它也富含不同的化石，如菊石和古長身貝屬等化石。 沿海地區擁有各種罕見的地質特徵，例如曲褶丶不整合面和海蝕平台。 這是一個具有特別地質價值的地區，當中涉及地層學丶古生物學和地貌學。 這亦是各院校和學生進行實地考察的重要地點，而科學家對該島進行了積極的研究。

Ma Shi Chau :
This island consists of the outcrop of the oldest sedimentary rocks in Hong Kong. It is also rich in fossils like Dictyoclostus, Ammonities, Antiguatonia and Duplophyllum. The coastal area contains a variety of rare geological features such as folding, uncomformities and wave-cut platforms. It is an area of special geological interest in the study of straigraphy, palaeontology and geomorphology. This is an important area for field studies by students of schools, colleges and unviersities. Active research has been carried out by scientists on this island.
