Among Belitong’s many geological treasures, the Adamelite Geosite stands out as a rare and fascinating formation. Found on two neighboring hills known locally as Bukit Baginda (the Woman’s Hill) and Bukit Meninda (the Man’s Hill), this site combines scientific importance with local folklore and natural beauty.
Geologically, the hills are made of adamelite, a type of I-type granite that is different from Belitong’s famous tin-bearing granite. Unlike typical granite, which contains abundant quartz (20–40%), adamelite has less quartz (only 5–20%) but is rich in hornblende, a black mineral with large, striking crystals. The rock also contains feldspar, plagioclase, biotite, and secondary minerals such as carbonate, limonite, and iron oxide. These mineral compositions give the hills a distinctive appearance and make them an important representation of I-type granite in Belitong UNESCO Global Geopark.
Beyond its geological significance, the site is steeped in local legend. The two hills are said to symbolize a man and a woman, with stories passed down through generations about their bond and spiritual meaning. This folklore adds cultural depth, making the site not just a natural wonder but also a place of heritage.
Today, Bukit Baginda and Bukit Meninda have become popular natural tourism destinations. Visitors can enjoy hiking trails that lead to panoramic viewpoints, where rolling green landscapes and the blue sea meet in breathtaking harmony. The twin hills are also favorite spots for photography, picnics, and enjoying Belitong’s peaceful countryside.
By blending geological heritage, cultural folklore, and eco-tourism, the Adamelite Geosite invites visitors to experience Belitong’s diversity in a single location. It is a place where science meets story, and where nature continues to inspire both locals and travelers from around the world.
