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.
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.
Petrification typically occurs in sedimentary environments where mineral-rich waters are present, facilitating the replacement process. Petrified wood is one of the most well-known examples of petrification, where tree trunks turn into stone while maintaining their original texture and structure.
15 maj 2012 · Today I found out how things become petrified, rather than just decaying normally. Petrifaction (also known as petrification) is a type of fossilization which leaves living organisms preserved as a type of stone.
Scientists study the facts about each fossil they find to find out clues about where they animal may have lived, what they ate, how old they were and how they died. There are two main types of fossils including mold fossils and petrified fossils.
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.
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.
