How do I find a geological map?

Download digital geologic maps for entire states from the USGS Mineral Resources Online Geospatial Data (MRDATA) website. Scroll down to the "Geologic Data" section. Contact your state geological survey. Many state geological surveys have detailed maps that can be downloaded or purchased.

Why are maps called 7.5 minute quadrangles?

Most USGS map series divide the United States into quadrangles bounded by two lines of latitude and two lines of longitude. For example, a 7.5-minute map shows an area that spans 7.5 minutes of latitude and 7.5 minutes of longitude, and it is usually named after the most prominent feature in the quadrangle.

What is the oldest geological map?

The oldest preserved geological map is the Turin papyrus (1150 BCE), which shows the location of building stone and gold deposits in Egypt. The earliest geological map of the modern era is the 1771 "Map of Part of Auvergne, or figures of, The Current of Lava in which Prisms, Balls, Etc. are Made from Basalt.

What is the meaning of the geologic map?

Geologic maps represent the distribution of different types of rock and surficial deposits, as well as locations of geologic structures such as faults and folds. Geologic maps are the primary source of information for various aspects of land-use planning, including the siting of buildings and transportation systems.

What is the primary definition of a quadrangle?

The first part of the word is 'quad' which means four. The second part of the word is 'angle'. So, the word quadrangle means four angles. A quadrangle is a polygon, or shape, that has four angles. A shape that has four angles will always have four sides so that means a quadrangle is also a quadrilateral.

What is a geologic quadrangle map?

A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad".

What is a quadrangle map?

In the making of topographic maps, the USGS subdivides the United States by using Latitude and Longitude lines to form the boundaries of four-sided figures called “quadrangles”. The maps are often referred to as quadrangle maps (or quad maps).

What map is best for showing detailed geologic information about an area?

Topographic maps are important in geology because they portray the surface of the earth in detail. This view of the surface shows patterns that provide information about the geology beneath the surface.
