Can we find fossils in the granite or marble mines Why?

Can fossils be found in granite?

Most scientists will say it is very unlikely for fossils of any kind of be found in granite because granite forms at great depths, under conditions that would obliterate organic tissue. … It is possible for the native sedimentary rock possessing fossils to be introduced to magma.

Can we find fossils in granite or marble mines?

From a geological point of view, this is impossible if you are looking at a marble or granite slab. Actually, if you are in front of a fossil, the material can neither be marble nor granite. There are other natural stones (often referred to as ‘marble’) that contain fossils of organic or animal origin.

Can marble have fossils?

There are no fossils in marble!

Limestone settles and solidifies slowly, which explains that you can often find beautiful and very well preserved fossils in it. … Limestone that has been “cooked” in this way (the precise term is “metamorphised”), transforms into marble.

Why would you not find fossils in granite?

This means that granite formed by a cooling process where the rock solidifies after it’s molten stage. Due to it’s extremely high temperature, granite has no fossils because during the molten stage it destroys and incinerates practically everything in its’ path.

Is granite a good place to look for fossils?

Plants and fungi, of course, also cannot live in such temperatures. So we don’t find fossils in granite, or any other igneous rock for that matter.

What rocks are likely to contain fossils?

Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils.

What type of rock is granite?

Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.

What is fossilized poop called?

Coprolites are the fossilised faeces of animals that lived millions of years ago. They are trace fossils, meaning not of the animal’s actual body.

How is marble formed?

Marble forms when a pre-existing limestone rock is heated to such extreme temperatures that the minerals grow larger and fuse together. The dark, foliated bands cutting through the marble are a different kind of metamorphic rock, such as slate.

Is limestone cheaper than marble?

Limestone is hands-down the more affordable of the two. Marble happens to be one of the most expensive decorative and expensive stones on the market. The price difference isn’t huge, but it’s definitely there. Also, limestone is much easier to find than marble.

Are marble and limestone the same?

The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. … Marble is usually light colored and is composed of crystals of calcite locked together like pieces of a jigsaw puzzle.

Which is harder limestone or marble?

Marble is a metamorphic rock, and limestone is a sedimentary rock. Limestone is more porous than marble, which is much harder. Limestone has white, gray and black colors, while marble comes in more diverse colors, from green to very light.

How long can it take to prepare a fossil?

However, if you want your remains to become a fossil that lasts for millions of years, then you really want minerals to seep through your bones and replace them with harder substances. This process, known as ‘permineralisation’, is what typically creates a fully-fledged fossil. It can take millions of years.

How do you tell if a rock has a fossil in it?

It is also a good idea to look for signs that the rock contains a fossil before trying to break it, part of a fossil may be visible on the surface of the rock. You can identify the limestone by it’s lighter grey colour and hardness, it should be quite hard to break without a hammer.

What are 2 forces that can expose once deeply buried fossils?
