«Rules and experience of using lithological triangle for constructing facies maps»
Lithological triangles are used in order to construct a geological lithofacies map under the conditions of significant bore-hole mud weight. The placement of these triangles’ points and their triangular coordinates do not always coincide. Gibbs triangle and Gibbs-Rosebom triangle are used in physical chemistry. The second is better developed. The planimetry theorems are the basis for the rules of constructing and using the triangle. When applying nomographic methods it is suggested to use a standard triangle to construct lithofacies maps (maps with a lithological cut).
