Knowra Geological mapping Geological mapping Geological mapping documents the distribution of rock units, structures, and geological relationships across an area, usually on a map tied to a defined scale.
Geological map : A map showing the distribution, age, and relationships of geological materials and structures at the surface. It is the standard product that organizes observations made during geological mapping.
Rock : A naturally occurring solid aggregate of minerals or mineraloids forming part of a planet's crust or mantle. Mapped units are commonly distinguished by their rock composition and texture.
Mineral exploration : The search for mineral deposits through geological, geochemical, and geophysical investigation. Geological maps identify rock settings and structures that may host ore deposits.
William Smith : An English surveyor and geologist who produced an influential geological map of England, Wales, and part of Scotland in 1815. His 1815 map demonstrated how fossils and strata could organize regional geological patterns.
Remote sensing : The acquisition of information about places or objects without direct physical contact, often using aircraft or satellites. It infers geological patterns over broad areas, unlike mapping based chiefly on ground observations.
Geological fieldwork : The direct observation and measurement of geological features in their natural settings. Mapping begins with field observations of rocks, contacts, and structures.
Lithostratigraphy : The classification of rock bodies according to their observable lithologic properties and stratigraphic relationships. It supplies the formal framework for naming and correlating mapped rock units.
Groundwater exploration : The investigation of geological formations to locate and assess usable groundwater. Mapped formations and structures help predict groundwater storage and movement.
Geological Society of London : A scientific society founded in 1807 to advance the study of geology. Its early members helped establish geological mapping as a systematic scientific practice.
Geophysical survey : The measurement of physical properties of Earth materials to investigate subsurface geology. It detects buried structures indirectly, complementing geological maps of exposed materials.
