Plummer's Ledge Natural Area in Wentworth, New Hampshire is a 3.5-acre (1.4 ha) plot of land protected by the State of New Hampshire to preserve unique geologic features called glacial potholes. Geologists usually account for the isolated potholes, now high and dry, by the plunging of melt water through vertical cracks or crevasses in the ...
The Seychelles microcontinent underlies the Seychelles in the western Indian Ocean made of Late Precambrian rock.. The granite outcrops of the Seychelles Islands in the central Indian Ocean were amongst the earliest examples cited by Alfred Wegener as evidence for his continental drift theory. [1]
Some of these boundary points are at physical locations, while others are in ice drill core sections, or have been defined chronometrically. The GSSP for the Danian Stage marks the end of the Cretaceous and the beginning of the Paleocene Series. [10] Located in Tunisia, the contact is described as a reddish layer at the base of a dark clay layer.

Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods at the surface of the Earth, such as seismic, gravitational, magnetic, electrical and electromagnetic, to measure the physical properties of the subsurface, along with the anomalies in those properties.
Palaeogeography (or paleogeography) is the study of historical geography, generally physical landscapes. [2] Palaeogeography can also include the study of human or cultural environments. [ citation needed ] When the focus is specifically on landforms , the term paleogeomorphology is sometimes used instead.
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
