Описание (английский):

Provides a unified series of symbols and ornaments for the representation of sedimentary rocks. The symbols and ornaments may be divided in two groups as follows: principal types; varia. They are reproduced in two tables which, being derived from a logical system, may be completed easily in case of need.

Overview

ISO 710-2:1974 - Graphical symbols for use on detailed maps, plans and geological cross-sections - Part 2: Representation of sedimentary rocks provides a unified, extendable set of graphical symbols and ornaments for depicting sedimentary rocks on detailed maps, plans and geological cross-sections. The standard organizes symbols into two complementary groups (principal types and varia) and reproduces them in tables to support consistent cartographic and geological representation.

Key topics and technical requirements

Two-group classification:

Principal types (Table 1) - diagrammatic ornaments for common sedimentary rock classes (clastic, chemical and organic sediments).
Varia (Table 2) - supplementary rock types, mineral inclusions and special features not suited to principal-type diagrams.

Elementary symbols and composition: basic marks (dots, lines, particles) represent grain size and texture (detritus, sand, silt, clay) and are combined to form ornaments for more complex rocks.

Representation rules:

Irregular arrangement indicates loose (unconsolidated) material; staggered/systematic arrangement denotes consolidated rocks.
Use of adjectives or petrographic qualifiers (e.g., argillaceous, calcareous) to refine rock identity.
Grain-size variations rendered by adjusting symbol size/density (examples: coarse/medium/fine sand).
Mineable deposits may be shown as black or densely cross-hatched areas; where this obscures detail, the underlying ornament is preferred and annotated in a legend.

Special symbols: conventions for dolomite, gypsum, anhydrite, sodium/potassium salts, peat, ferruginous/siliceous character, caverns, concretions, mineral inclusions (feldspar, mica, glauconite), volcanogenic admixtures, fossils, and others.

Extensibility: tables are derived from a logical system and can be completed or adapted to specific mapping needs. Box referencing uses column/line notation (for example, 3/12).

Applications and who uses it

ISO 710-2 is intended for professionals who produce or interpret geological maps, plans and cross-sections, including:

Geological survey organizations and cartographers

Mining and exploration geologists

Environmental and engineering geologists

Academic researchers and students in stratigraphy and sedimentology Using standardized graphical symbols for sedimentary rocks improves clarity, interoperability and legibility across maps and technical reports.
