The study of geoheritage potential in the Northern Bangka Island as future geopark of Bangka Belitung Islands Province

The background of this study is the geological richness in Bangka Island which is geosite that has significance in science, scarcity, aesthetic, and education. Activities in Geopark are not only limited to geological, but also archeological, ecological, historical, and cultural aspects. In the activities to protect natural heritage from destruction or environmental degradation, Geopark area has become the location of the examination of the enforced protection method. Besides, Geopark is also fully open for any activity such as study and research of any science and appropriate technology. The aims of this study are: to inventory the spread of geological sites in the northern Bangka Island, to determine the sites of geological heritage that will be set as sites should be conserved. The data was taken from rock outcrop that was eventually examined using XRD, rock and mineral petrography. This research showed that from 5 locations there were 2 types of dominant rock outcrops metamorphic rock and igneous rock (granite), in addition there are also other types of rock that are quarternary, namely limestone reefs and conglomerates. Its uniqueness and can be used as a geosite location.
