TS ISO 710-2

TS ISO 710-2 addresses the graphical symbols and ornamentation used to represent sedimentary rocks on detailed geological maps, plans and geological cross-sections. In practice, these symbols help communicate not only the rock type but also the visual cues that make sedimentary units readable and comparable across geological drawings.

Why sedimentary rock notation matters

Sedimentary rocks form from deposited material that is later compacted and lithified. Because units such as sandstone, limestone, shale and conglomerate may differ in texture, layering and origin, geological documents often rely on consistent graphic notation to show them clearly. A unified symbol system supports interpretation of map boundaries, stratigraphic relationships and the distinct appearance of units on different drawings.

What this part covers in general terms

According to the scope, this part provides a unified series of symbols for representing sedimentary rocks on maps, plans and cross-sections. In broader technical terms, such notation may combine line patterns, fills, hatching or other graphic devices so that rock categories can be recognized quickly and consistently. The value of the system is clarity: it allows geological information to be read efficiently while keeping the same visual language across different document types.

• The focus is on sedimentary rocks, not on the full geological symbol system as a whole.
• The same notation family is intended for detailed maps, plans and cross-sections.
• Consistent symbols improve readability and reduce ambiguity in geological graphics.
• The approach supports visual identification of lithological and stratigraphic differences.
