Which rock type can contain fossils?
Sedimentary rocks are the primary rock type that can contain fossils. These rocks form from the accumulation and compaction of mineral and organic particles, often in water environments, where organisms can be preserved. Common examples of sedimentary rocks that may contain fossils include limestone, shale, and sandstone. Fossils are typically found in layers of sedimentary rock that have preserved the remains of once-living organisms.
Does conglomerate contain fossils?
Conglomerate can contain fossils. Fossils may be trapped within the rock during its formation when sediment accumulates and solidifies. The presence of fossils in conglomerate can provide insights into the age of the rock and the environmental conditions at the time of deposition.
What does it form from when broken pieces of minerals and rock fragments?
When broken pieces of minerals and rock fragments accumulate, they form sediment. Over time, this sediment can undergo processes such as compaction and cementation, ultimately leading to the formation of sedimentary rock. Sedimentary rocks often contain layers and may preserve fossils, providing insights into Earth’s history.
Does marble have a fossil?
Correctly defined, marble is a metamorphosed limestone. This means it has undergone great heat and/or pressure which usually destroys all fossils in it. Commercially available rock for ornamental purposes is sometimes referred to as marble, but it is actually limestone and this will often contain fossils.
Why do the other two main types of rocks not contain fossils?
Igneous rocks form directly from a melt, hence there are no fossils contained within them. Metamorphic rocks are pre-existing rocks (sedimentary, igneous, or even metamorphic rocks themselves) which have undergone significantly increased pressures and/or temperatures. Any structure(s) or fossils which may have been present tend to be destroyed, reworked, or have their character diminished. Additionally, the presence or absence of water can often cause a wide variation in the mineral assemblages.

Which type of rock may contain fossil?
fossils almost allways occur in sedementary rock. this is the only way to get fossils without burning or cruching the fossil. you sometimes get fossils in igneous rock, but this is very rare. igneous rock fossils do not have any actual "fossils" in them, they are just impressions.
Does geolgic have to do with a type of rock may contain fossils?
No, geolgic is not a word in English
Does conglomerate contain fossils?
Conglomerate can contain fossils. Fossils may be trapped within the rock during its formation when sediment accumulates and solidifies. The presence of fossils in conglomerate can provide insights into the age of the rock and the environmental conditions at the time of deposition.
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.

What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
How can I find ammonite fossils?
To find ammonite fossils, you can search in areas where sedimentary rocks are exposed, such as cliffs, quarries, or beaches. Look for rocks with spiral patterns or ridges, as these may contain ammonite fossils. Use a rock hammer or chisel to carefully extract the fossils from the rock. Be sure to follow any local regulations or guidelines for fossil collecting.
Would you be less likely to find fossils in metamorphic rock than a sedimentary rock?
Metamorphic rock can contain fossils, but since these rocks form under intense heat and pressure where stone flows something like taffy, the fossils will be highly degraded and distorted.Sedimentary rock forms when layers of silt are Why_are_you_less_likely_to_find_fossils_in_metamorphic_rock_than_sedimentary_rockon the bottom of a body of water. When conditions are right, layers form quickly and are not disturbed and little oxygen is present, dead creatures that fall on that bottom can become entombed in preserved at the layers are increasingly compressed, eventually cementing into rock.
Where do rocks come form?
Nearly all rocks had their beginning as magma - molten rock. This forms igneous rock that weathers to form sedimentary rocks. Sedimentary rock may be changed by heat and pressure to form metamorphic rock. The exception is limestone which is formed by chemical precipitation or from fossils.
What are the components of limestone rock?
Limestone rock primarily consists of the mineral calcite, which is a form of calcium carbonate. It may also contain varying amounts of other minerals such as clay, dolomite, quartz, and aragonite. Fossils, shells, and other organic materials can also be present in limestone.
Does marble have a fossil?
Correctly defined, marble is a metamorphosed limestone. This means it has undergone great heat and/or pressure which usually destroys all fossils in it. Commercially available rock for ornamental purposes is sometimes referred to as marble, but it is actually limestone and this will often contain fossils.
