A Summary of Geologic Information used by the Intermountain Forest Tree Nutrition Cooperative to Estimate Potassium Content of Rock Item Info

The IFTNC currently classifies parent materials based on four rock types: Basic-Igneous (Basaltic), Acid- Igneous (Granitic), Metasedimentary, and Mixed (glacial till). In order to further clarify health-related issues and their potential association with parent materials, a more specific classification of parent materials according to content of certain critical elements, especially potassium (K) would be helpful. Such a classification system should allow us to categorize the rock types found on geologic maps and publications according to element content and contribution to soil-available nutrient supply. The purpose of this paper is to present a classification of rock types based on K content; the discussion of rock contribution to soil-available K supply will be discussed separately. The following classification system was developed based on a literature review of basic mineralogical, petrographical, geochemical and geological information.
