TS ISO 710-2/D1

TS ISO 710-2/D1 is the part of the graphical-symbol system used on detailed geological maps, plans, and cross-sections that deals with sedimentary rocks. In geological drawing, symbols help communicate rock type, bedding, structural relationships, and interpreted features in a compact visual form. Standards of this kind provide a common graphic language so that the same geological information can be read consistently across different documents and by different users.

Why sedimentary-rock symbols matter

Sedimentary rocks form through the accumulation, transport, and lithification of sediments. On maps and cross-sections, units such as sandstone, shale, limestone, and conglomerate are often distinguished not only by color but also by standardized patterns and symbols. This makes detailed interpretation easier, especially where boundaries, lithologic changes, and structural relations need to be shown clearly and compared across documents.

Technical context of this document

• Covers the use of graphical symbols on geological maps, plans, and cross-sections.
• This is Part 2, focused on the representation of sedimentary rocks.
• Supports visual consistency and comparability in geological presentation.
• Provides a shared technical language for drawing and symbol use.

In geology, hydrogeology, mining, and engineering projects, symbol standards are valuable when field observations are transferred into drawings. Technically, the purpose is not to define how geological data are collected, but to harmonize how that information is presented visually. That helps teams produce documents that are easier to read, compare, and interpret.
