BRIEF HISTORY
The IS0 Recommendation R 710/I, Graphical symbols for use on detailed maps, plans and
geological cross sections - Part I : General rules of representation, was drawn up by Technical
Committee ISO/TC 82, Mining, the Secretariat of which is held by the Deutscher Normenausschuss
(DNA).
Work on this question by the Technical Committee began in 1959 and led, in 1963, to the
adoption of a Draft IS0 Recommendation.
In January 1965, this Draft IS0 Recommendation (No. 730) was circulated to ail the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature, by
the following Member Bodies :
Belgium
India Spain
Brazil Italy South Africa,
Chile
Japan Rep. of
Czechoslovakia
Korea, Rep. of Sweden
France
Netherlands Turkey
Germany New Zealand U.A.R.
Greece Poland U.S.S.R.
Hungary Portugal
One Member Body opposed the approval of the Draft :
Yugoslavia
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council
which decided, in April 1968, to accept it as an IS0 RECOMMENDATION.

PART I : GENERALRULES OF REPRESENTATION
FOREWORD
In many spheres of technology, science and economics, data on the geological formations and
structure of the earth’s crust are indispensable. Often, this information is given in the form of maps
and plans annotated by conventional symbols.
Until the present time, different symbols have been used, not only from country to country, but
often for various fields of application within the same country, the result being entirely different
representations of the same facts or geological data. Under these circumstances, it has become
necessary to eliminate these differences as far as possible and to reach some agreement on the use of
a standard set of symbols and ornaments, so that maps and plans can be understood in the same way
in all countries and in all languages.
1. SCOPE
1.1 This IS0 Recommendation is intended to give general rules for the representation of rocks and
minerais on maps, plans and detailed geological cross-sections.
1.2
Other IS0 Recommendations will contain the symbols for rocks and minerals, so that the
complete study will cover the following items :
Part I - General rules of representation;
Part II - Representation of sedi
