Structural formula

Structural formula

The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged. The chemical bonding within the molecule is also shown, either explicitly or implicitly. Unlike chemical formulas, which have a limited number of symbols and are capable of only limited descriptive power, structural formulas provide a complete geometric

Graphical Representation of Metamorphic Mineral

Abstract. A correct graphical representation of a mineral paragenesis is possible, only if the number of components, constituting the minerals does not exceed four, because only four components can be represented in space at the corners of a tetrahedron. A two dimensional representation is, of course, greatly desired and,

Gold Mineral Properties   Geology

Gold Mineral Properties Geology

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.

GRAPHICAL REPRESENTATION OF GRAIN AND HILLOCK

For a graphical representation of grain orientations, the three orientation parameters may be assigned to three basic colours that are red, green and blue. Each grain in a micrograph may thus be stained by a unique colour which, on the other hand, can be interpreted in terms of orientation parameters by comparison with a colour legend.
