Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 958-1989 "Regional Geological Map Legend", this standard and GB/T 958-1989 "regional geological map legend" phase
The main technical changes are as follows.
--- by point, line, face pattern Legend content first, code, symbol legend in the order after the re-arranged;
--- Increased number of geometric point-like elements (see 4.1);
- Atlas of geological structure and geology (phase, band) increased by 165 (see 4.2, 4.3);
The rock pattern legend has increased by 279 (see 4.4);
- an increase of 77 (see 4.5) for the mineral, ore, ore body (layer)
--- map of landform type increased by 72, code 440 (see 4.10);
The geological unit code has increased by.201 (see 4.11);
--- The name of the rock has increased by 525 (see 4.12);
--- mineral, ore name code increased by 177 (see 4.13);
- rock phase code increased by 132 (see 4.14);
--- The method for determining the age of geology has increased by 33 (see 4.15);
- reclassification and merging of the geological point-like elements of the legend, geological structure of the legend, geological causes (phase, with) the legend (see 4.1,4.2,4.3);
--- rock pattern legend, the rock characteristics of the composition, structure, structure and the basic pattern of the three rocks into a chapter, and made a detailed
Classification, especially for metamorphic rocks subdivided into 12 parts (see 4.4);
- veins return to the rock pattern legend, 5 categories of veins using a common style, respectively, by the orange said alkaline veins, dark green that super
The basic veins, the green represents the basic veins, the blue represents the neutral veins and the red represents the acid veins, whose lithology uses the corresponding
Intrusion rock symbols (code) to distinguish (see 4.4);
Geological body unit code from old to new by stratigraphic unit, geological age unit, rock stratum unit (including informal stratigraphic single
Etc.), the age and unit of the invading rock and its order, the code indicates that it is associated with the latest age and geological year
On behalf of the division of content (4.11);
- the name of the rock code by the three rock, made a more detailed system classification (see 4.12);
- the original "mineralization age, genetic type, ore pattern and ore body, ore layer representation method example" "sedimentary construction legend creation and
Application examples "in two parts, from the text to adjust out as a standard data attached to the statement (see Appendix C, Appendix D);
Geological terms English has increased by more than 5,000 articles.

Introduction
With the deepening of geological survey and research in China, database technology, geological information application technology and the rapid development of information technology
Exhibition, geological map reflects and carry the amount of information is increasing, published in 1989, the implementation of GB/T 958-1989 "regional geological map legend" has been
Can not fully meet the current needs of regional geological maps and spatial database construction, for which the China Geological Survey in.2009 to open the project
The revision of the "Regional Geological Map Legend" (GB/T 958-1989) standard was completed and the revision was completed in May.2013. Newly revised "area
Geological map of the legend "to take full account of the regional geological map of the compilation, drawing, publishing and spatial geological map database construction status and needs, the largest
Limit the number of expansion of the legend, including the legend of 4466, the new legend 2165.
The implementation of the standard implementation of China's geological map of the compilation and printing, publishing work of standardization, standardization play a positive push for
Use, to promote computer-aided preparation of geological and mineral maps provide a good foundation.
Regional Geological Map Legend
1 Scope
This standard specifies the code, symbol and pattern of the regional geological map legend, and its representation and principles.
This standard applies to regional geological survey, field mapping and indoor geological map, drawing and publishing; editing other types of thematic geological maps
Can refer to the implementation.
2 terms and definitions
The following terms and definitions apply to this document.
2.1
Legend legend
Geological map on the point, line, surface elements that the geological attributes of the symbol or code of the general term, is the map with symbols, code, pattern and pattern, color
The representation of the method and the description of the method.
2.2
Code code
A set of explicit rules that represent information in discrete form by characters, symbols, or signal symbols.
3 General
3.1 Basic principles
3.1.1 Each legend represents only one geological content to ensure the uniqueness of its geological meaning.
3.1.2 Representation of rocks and minerals, regardless of the use of monochrome or multi-color, the symbol of the symbols and patterns of geological properties meaning
constant.
3.1.3 Illustrations of rocks and minerals, this standard lists only the most common types of basic rock and mineral classification.
3.1.4 on the geological work has been used for many years, agreed routines, such as no principled objections, to retain the original habits.
3.1.5 In the drawing of the standard does not have the standard, the standard can be within the scope of the principles, according to the specific circumstances, to expand the corresponding
New legend, but can not change the existing legend and its meaning.
3.2 Classification and coding rules
3.2.1 The standard code of this standard adopts the compound coding rule, which is expressed in four levels of 10-bit code, as follows (see Figure 1).
