Document Summary

Inorganic (i. e. , no c-h bonds typical of the molecules of life: ex= ice is kind of a mineral since it has a defined chemical formula and a crystal structure, diamond, graphite, Shells are not minerals cuz they belong to live organic organism. Theeth and bones are organic so not minerals. Volcanic glass / obsidian is not a mineral cuz it lacks a atomic lattice ctrucute, so its not a true mineral. Sugar is not a mineral but its has a cystline stutuecre but produces from organic process. Cremation diamond are man-made and contain organic matter. Combination of elements to form minerals depends mainly on three characteristics of atoms of that element: abundance of available elements (w/in crust) big 8. O : 45% si : 27% al : 8% fe : 5% ca : <5% mg : <5% na : <5% k : <5: temperature & pressure at time of formation.
