Munsell Soil Color Book - Carta de Cores Munsell para Solos

For color identification of rocks, archaeological specimens, animal pelage, and other natural products.

 Munsell Soil Color Book was developed with the U.S. Soil Conservation Service for classifying the
color of the soil. This soil color book can also be used with rocks, archeological specimens, and other natural materials. Munsell Charts are a standard tool used by geologists, civil engineers, and soil scientists.

This revised edition features the same colors available in previous books plus additional color charts. Included are a 10Y and 5GY soil chart for glauconite soils, a 5R soil chart for Australia and Southeast Asia, and a 7.5R soil chart for tropical and semi-tropical soils. A Munsell high value, low chroma “white” page shows half steps from 8.5 to 9.5 in value with chromas of 1 and 2 for N, 7.5YR, 10YR, and 2.5Y. Use this page to describe carbonate, silica, gypsum, and soluble salt precipitates and evaporites common to arid and semi-arid environments as well as very light-colored parent materials such as diatomaceous earth and volcanic ash. The book’s light gray pages decrease sun glare. The color chips are recessed into each water-resistant page to allow dirt and debris to be wiped off easily with less effect on the color chips. 2009 Revised Edition, 2022 Production. Chart Size: 6˝ x 8˝.

Openings between chips allow easy visual comparison with soil samples. Illustrations of soil grain structures, charts for estimating proportions of mottles and coarse fragments, color name diagrams, and instructions are all included. Color chips are mounted on neutral gray, 7.25x4.25in (184x108mm) water-resistant pages in an 8x6in (203x152mm) loose-leaf binder.
