Chapter 5 Flashcards
It is a special-purpose map made to show geological features.
Geologic map
These are shown by using standardized color or symbols to indicate where they are exposed at the surface.
Rock Units or geologic strata
It is an essential tool in geology, used to understand the composition, history, and structure of an area, providing critical information for various applications, including resource exploration, environmental assessments, and land use planning.
Geologic Map
It provides critical data for understanding Earth’s structure. It represents rock formations and their structural links, aid in understanding a region’s tectonic and depositional history
Geologic Map
It is critical for identifying areas vulnerable to natural disasters including earthquakes, landslides, and volcanic eruptions.
Geologic mapping
Key components of geologic map that has Distinct colors and patterns indicate different types of rocks or geological formations.
Rock Units (lithologies)
Key components of geologic map that faults, folds, and fractures are represented using unique symbols.
Structural features
Key components of geologic map that lines demarcate boundaries between different rock units.
Geologic Contacts
Key components of geologic map that provides explanations for the map’s symbols, colors, and patterns
Legend/key
Key components of geologic map that indicate abbreviations and symbols on the map indicate the age of the rock formations.
Geologic Time Symbols
It is the foundation of geologic mapping
Fieldwork
The process of creating a geologic map where geologists traverse the landscape, making direct observations of rock types, structures, and relationships. They measure the orientation of rock layers, collect samples, and note the locations of key features like faults and folds.
Field Observations
The process of creating a geologic map where modern geologists use satellite imagery, drones, and aerial photographs to map large, inaccessible areas.
Remote Sensing and Aerial Imagery
Tools that allow rapid
identification of broad-scale geological patterns and structural features, which can then been verified through fieldwork
satellite imagery, drones, and aerial photographs
The process of creating a geologic map where Techniques such as seismic surveys, ground-penetrating radar (GPR), and magnetic surveys provide valuable subsurface information.
Geophysical Methods
It has revolutionized geologic mapping by allowing geologists to store, manipulate, and analyze geospatial data.
Geographic Information Systems (GIS)
These methods are particularly useful in areas where rock units are covered by thick layers of soil or sediment, as they can reveal the hidden structure and composition of ine subsurface.
Geophysical methods
platforms that enable the creation of highly detailed maps that can be easily updated and shared
Digital mapping
This facilitates the integration of other datasets, such as topography, hydrology, and land use, providing a more comprehensive understanding of an area.
Geographic Information Systems (GIS)
It is an instrument used for determining direction.
Compass
basic equipment for any geologist as it is the tool used for collecting
samples.
Geological hammer
Tool used to make the first analysis of rock samples in the field before further analysis is performed in the laboratories.
Hand held lens
tools use to do all important observation when reading geologic map
Field notebook, masking tape and marker pens
It is essential for the exploration and management of oil and gas resources.
