Popis: This paper discusses a research conducted in Dayang Bunting and Tuba Islands, Langkawi, Malaysia, in an effort to promote these islands as educational geosites to explain the process and impact of contact metamorphism to the public. The research activities involves evaluation of microscopic rock samples from the closest to the farthest distance from the metamorphism contact zone. The evaluation involves examining grain size, zonation, shape, and fabric of minerals in rock samples. Pronounced changes were observed from different distances from the contact zone as indicated by the change in grain size, grain shape and zoning in the mineral. These informations are stored in a database that is accessible to the public in the future.
