Mineral replacement fossils are formed when minerals gradually replace the organic material of an organism, preserving its shape and structure. This process occurs when the organism is quickly buried by sediment, cutting off oxygen and preventing decomposition. Over time, minerals such as silica, calcite, or pyrite gradually infiltrate the spaces left behind by the decaying organic material, creating a replica of the original organism.
What else can I help you with?
What kind of formations can be found inside a rock, such as sedimentary layers or mineral deposits?
Common formations found inside rocks include sedimentary layers, mineral deposits, fossils, and crystal structures. These formations provide valuable information about the rock's history and the conditions under which it formed.
Sedimentary rocks that formed organically typically contain what?
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
What is an example of of mineral replacement?
petrified wood
Is limestone a silicate mineral?
No. Dolomite is formed by the replacement of Calcium in the mineral calcite by Magnesium, giving the chemical formula (Ca,Mg)CaCO3. Rocks formed largely of calcite are called limestones, and those which show extensive Magnesium substitution in calcite are called Dolomitic limestones.
What mineral family can the Mica mineral change to when Gneiss is formed?
The Mica mineral can change to the mineral group known as amphiboles when Gneiss is formed. This transformation occurs due to the high pressure and temperature conditions during the metamorphic process.
The way fossils are formed in very dry places is called what?
Fossils can be formed by:MummificationPetrificationDesiccationRelated question on Answers.com:How are fossils formed?
In terms of fossils what is Replacement?
fossil replacement is when you Suck MY MEAT ! ;D
Would a fossil clam be classified as a mineral?
A fossil is not a mineral.
Is calcite a mineral associated with fossils?
yes
How are gasses formed?
by fossils
What are four ways that organisms can be fossilized?
imprints gastroliths coproliths molds
Does and organism have to be buried to become a fossil?
No, an organism does not have to be buried to become a fossil. Fossils can form through a variety of processes, such as compression, mineral replacement, or petrification, which can occur even without burial.
How would a fossil form through mineral replacement?
Fossils form through the process of mineral replacement beginning when an organism dies and is buried. Groundwater seeps around the organism, and the minerals in the water gradually replace the minerals in the hard parts of the organism. Over time these minerals turn into a stone replica of an organism.
What mineral can fossils be found in?
It depends what fossil you're talking about but normally fossils are found in sedimentary rocks. But diatomaceous earth, and limestones contain fossils, or are made of fossils.
Can fossils be found in quartz?
Fossils are typically found in sedimentary rocks, where the conditions support the preservation of organic remains. Quartz itself is a mineral and does not contain fossils; however, it can occur in sedimentary rocks that also contain fossils. In some cases, fossils may be found encased in quartzite, which is a metamorphic rock formed from sandstone rich in quartz. Overall, while quartz can be associated with fossil-bearing rocks, it does not directly contain fossils.
How do you get the scientist to make fossils come back to life?
You don't. A fossil is not the animal/plant, it is an impression, altered by the replacement of one mineral by another due to burial with usually some pressure/heat involved.
What is a common carbonate mineral that replaces a mineral in fossils?
Calcite is a common carbonate mineral that often replaces the original mineral in fossils during the fossilization process. Calcite can help preserve the structure of the fossil while replacing the original material.
