A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
The long-term preserved geologic record of a sedimentary basin is a large scale contiguous three-dimensional package of sedimentary rocks created during a particular period of geologic time, a 'stratigraphic succession', that geologists continue to refer to as a sedimentary basin even if it is no longer a bathymetric or topographic depression.

The Roof of the World or Top of the World is a metaphoric epithet or phrase used to describe the highest region in the world, also known as High Asia. The term usually refers to the mountainous interior of Asia, including the Pamirs , the Himalayas , the Tibetan Plateau , the Hindu Kush , the Tian Shan , the country of Nepal , and the Altai ...
The letters A and B at the top correspond to the line labeled A--B on the smaller map. In this example, the vertical scale is exaggerated compared to the horizontal scale. A cross section or cross-section , in geology , is a diagram representing the geologic features intersecting a vertical plane , and is used to illustrate an area's structure ...
The Paris Basin is a geological basin of sedimentary rocks. It overlies geological strata folded by the Variscan orogeny. It forms a broad shallow bowl in which marine deposits from throughout periods from the Triassic to the Pliocene were laid down. Their extent generally decreases with time.
In the essay, titled "The Grace of Water," she traces the river's history, from the geological forces that shaped the basin to today. "I'm in awe of the power of the Columbia," Pearkes said.
Bushveld Igneous Complex geologic map and mine locations. The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion [1] [2] within the Earth's crust. [3] It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.
Imagine life with no humans. One group of researchers has done exactly that -- and they even made a map to show how the world might look sans homo sapiens. SEE ALSO: California drought may ...
