Explanation:
Minerals & their Properties
Minerals are defined as the naturally occurring, solid inorganic chemical compounds. They have an orderly internal structure with definite chemical composition.
Fossils usually contain single or multiple minerals such as Calcite, Quartz, Phosphate etc. Sometimes minerals are visible in the crystalline form in fossils. So, we cannot say that minerals are made of fossils. Instead, fossils can be made of minerals.
According to the prime and standard definition given by scientists, minerals are usually composed of chemical compounds or multiple compounds such a Halite which composed of Sodium and Chlorine elements. But they can be made of just one substance or element.
Now talking about the tiny grains of sand, that are made of minerals. So, instead of saying that minerals are composed of tiny grains of sand, we should say that sand is made of minerals. The most common mineral which forms sand is Quartz. Sand has a versatile mixture of substances besides minerals.
