In some cases, there are minerals possess all the criteria except the internal structure called mineraloid, such as amber, obsidian, opal and etc.To be classified as a true mineral, a substance must be a solid and have a crystal structure.It must also be an inorganic, naturally-occurring, homogeneous substance with a defined chemical composition.The chemical composition may vary between.Read More
Geology - geology - study of the composition of the earth as a discipline, mineralogy has had close historical ties with geology.Minerals as basic constituents of rocks and ore deposits are obviously an integral aspect of geology.The problems and techniques of mineralogy, however, are distinct in many respects from those of the rest of geology, with the result that mineralogy has grown.Read More
