Discover the fascinating geological history beneath Hong Kong — from 400-million-year-old Devonian rocks to spectacular hexagonal volcanic columns.
The Geological Society of Hong Kong is a non-profit organisation that promotes geological and earth science studies within Hong Kong and the adjacent region. We organise local and overseas field trips, as well as lectures. The Society publishes a journal (The Hong Kong Geologist) and bulletins dealing with a variety of earth science subjects.
Established by a group of local geologists in 1982, the Society holds regular geological conferences and seminars, and organises field trips for both members and non-members. At present, the society maintains a steady membership of about 250, including professional geologists from the public and private sectors, academia, as well as teachers, students and amateurs.
We conduct free educational sessions and presentations at schools, colleges, and community events across Hong Kong, spreading awareness of earth sciences.

Quartz crystallizes from silica-rich solutions usually associated with volcanic or hydrothermal activities. The sample shown displays a fibrous vein — a quartz pseudomorph after crocidolite (an asbestos mineral), alternatively known as "tiger-eye". When silica fluid flows along structures and interacts with crocidolite, SiO₂ replaces the original chemical composition while preserving the fibrous habit and colour. The golden hue is subsequently tinted by iron oxides, making it a prized gemstone.
Joining The Geological Society of Hong Kong has been an eye-opening experience. I've had the chance to explore Hong Kong's diverse geological landscapes and learn from experts in the field.
The educational outreach programs organized by the society have made a significant impact on students' understanding of geology. It's inspiring to be part of such meaningful initiatives.
The society's commitment to geological conservation is commendable. Being involved in conservation projects has allowed me to contribute to the preservation of our natural heritage.
From Devonian sedimentary rocks to Mesozoic volcanic formations, Hong Kong's geology tells a story over 400 million years in the making.
