Abstract: The Sarawak petrified woods occurred within the Tertiary Kayan Sandstone in the vicinity of Bungo Range. They were .preserved for million of years by the process of petrification that transformed the wood into silica (opal or chalcedony). It is unique because of its colour and preservation where the cell structures and grain of wood were clearly retained. These hidden treasures must be preserved for future generations and the government bodies concerned are greatly needed for conservation.

 

Abstrak: Kayu terpetri Sarawak wujud di dalam Formasi Batu Pasir Kayan berusia Tertier terIetak berhampiran dengan Banjaran Bungo. Kayu-kayu telah terawet dalam jutaan tahun melalui proses pempetrian yang menukarkan kayu kepada silika (opal dan kalsedoni). Kayu tersilika amat unik kerana kepelbagaian warna dan pengawetannya di mana struktur sel dan. tekstur asal kayu masih dikekalkan. Usaha badan-badan kerajaan berkaitan amat diperIukan ke arah pemuliharaan khazanah tersembunyi milik negara ini untuk generasi akan datang.
