It's called fossilization, and in particular, replacement and recrystallization.
these rocks are called fossils
There is no material simply called "silicate," so this question does not have an answer. There is a mineral called silica. There is a whole class of minerals called silicates as a group. There is the element silicon. Once you specify which specific material you need the density of, then you can get an answer.
Sedimentary rock
A rock containing minerals is called an ore.answ2. A Mineral is defined as "A naturally occurring, homogeneous solid, with a defined chemical composition and a highly ordered atomic arrangement."An Ore on the other hand, is "A metalliferous mineral or aggregate of metalliferous minerals mixed with a gangue (unwanted material) and that can be exploited at a profit."
It's called 'calcification'
Fossilization
When plants and animals (any living matter) decay, their remains are in the soil, in the material called humus.
It's called fossilization, and in particular, replacement and recrystallization.
