TS ISO 710-7

TS ISO 710-7 covers the graphical symbols used to represent tectonic phenomena on detailed geological maps, plans, and geological cross-sections. It is concerned with the visual language that allows structural relationships, deformation, and displacement to be shown consistently on technical geological drawings.

The role of tectonic symbols in geological representation

In general technical practice, tectonic symbols help express features such as faulting, folding, and other structural conditions in a compact and readable form. They link field observations to map or section geometry by using a shared graphic convention, which makes geological documents easier to compare and interpret across different scales and projects.

According to the scope of this standard, the covered subject is the series of graphical symbols for tectonic phenomena, especially on detailed or large-scale maps, plans, and geological cross-sections. The focus is therefore on drawing conventions rather than narrative description, so that the same structural feature can be depicted in a consistent way.

Why this matters in geological mapping

• Tectonic symbols transfer structural observations from the field into a drawing format.
• A common symbol language improves comparability between maps and cross-sections.
• In cross-sections, symbols help show the relationship between surface data and subsurface geometry.
• They support faster and more consistent communication in detailed geological work.

Geological symbol systems are not just graphical decoration; they are technical tools for preserving the meaning of the data. This standard belongs to that broader family of map-symbol conventions and provides a shared framework for presenting tectonic features in a readable, disciplined way.
