Review of the Fossil Woods in Vietnam's Territory Hung Nguyen Huu

Fossil woods have been found in many localities in Vietnams territory in geological formations of the Devonian, Triassic, Jurassic, Cretaceous, Paleogene, Neogene, and Quaternary periods. Originally, they were woody plants belonging to phyla Lycopodiophyta, Polypodiophyta, Gymnospermae, and Angiospermae. After death, the plants were buried under specific conditions and the organic components of the wood were replaced by minerals such as agate, opal, calcite, etc. At present, fossil woods are used for decoration in homes and offices and are exhibited in museums and parks. In this paper, we present basic information on fossil woods, their geological ages, research methods used to study them, and their scientific and artistic significance.
