Product Description

Munsell Rock Color Chart

Product code: M50315B

The Rock-Color Chart

The pages within this book are cleanable and can be exposed to the standard environmental conditions that are met in the field. This does not mean that the book will be able to withstand all of the environmental conditions that it is exposed to in the field.

For the cleaning of the coloured pages, please make sure not to use a cleaning agent or materials that are coarse in nature. These materials could either damage the surface of the colour chips or cause the colour chips to start to delaminate from the pages.

With the specifying of the rock colour it is important to remember to replace the rock colour chart book on a regular basis so that the colors being specified are consistent from one individual to another. We recommend that you mark the date when you started to use the the book. There is a space provided on the pevious page.

It is recommend that you replace the book after two years of use. This time frame is suggested based upon typical usage patterns and conditions.

Purpose

 

 

 

 

This chart is designed primarily for field use, although it indicates the range of rock colours for all purposes. Names for colours other than those shown on the chart can be found in The Universal Color Language and Color Names Dictionary (publication PB 265-225, available from the U.S. Department of Commerce, National Technical Information Services {NTIS}, Springfield, VA 22161).

Using the chart

The chart is chiefly of value in describing the colors of medium-to fine-grained rocks but is also helpful in working with coarse-grained rocks. In describing very coarse-grained rocks, such as porphyritic granites, it is necessary to give the colour of each mineral. The chart is designed to cover the range of the chief   rock-forming minerals such as feldspar, quartz, mica, and hornblende. If the rock is not too coarse grained, a blending of the individual colours can be secured by spinning the specimen like a colour disc or by looking at the rock from a short distance and thus getting a monotone that can be matched with the chips on the chart. The number and range of colours on the Rock-Colour Chart are based on studies of more than 1,300 selected rock specimen collected from the United States. The colours of these rocks were plotted on the Munsell charts, which served as a basis for selecting the colours to be included. It is believed that the full range of rocks is covered by the chart, except possibly for very rare rocks of high chroma. A neutral mask is included with the chart for isolating individual colours.

 

 

 

Wet vs. Dry

For most rock colours, the chart will serve for both wet and dry specimens. It will usually be found that wetting a rock specimen merely decreases the value, that is, makes the specimen darker, but does not change the chroma. Accordingly, the Rock-Color Chart includes colours as far as possible into the dark range in order to cover wet specimens as well as dry. For the first time, the chart includes glossy chips for some of the dark colours. This was necessary to retain colour accuracy within the system of notation used in the chart.
