In geology, petrifaction or petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Summary: Petrified fossils result from permineralization, the replacement of once-living matter by minerals. Solutions containing silicates, carbonates, iron or other minerals seep into the gaps and spaces between the cells, first encasing the cells and eventually replacing the cells themselves.
Petrification can provide essential information about ancient ecosystems and climate conditions due to the preserved structures within fossils. Not all organic materials undergo petrification; factors like rapid burial and mineral presence are crucial for this specific type of fossilization.
28 lut 2024 · A fossil is the preserved remains, impression, or trace of any once-living organism from a past geological age. These include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.
25 lut 2019 · What Makes It Petrified? When a fossil organism is subjected to mineral replacement, it is said to be petrified. For example, petrified wood may be replaced with chalcedony, or shells replaced with pyrite. This means that out of all fossils, only the creature itself could be fossilized by petrification.
1 mar 2024 · This study investigates the mineralization processes of the world's longest petrified wood (Koompassioxylon elegans), BT1, located in Tak, Thailand, an extraordinary and rare specimen with significance for scientific, educational, geotourism, recreational, geopark, and geoheritage purposes.
8 lip 2024 · Minerals play a pivotal role in petrification. As the organic matter decays, minerals such as quartz, calcite, and pyrite replace the original material. The type of mineral involved can affect the color, hardness, and other properties of the petrified fossil.
