Brownstone National Park: dwellings made from blocks of Triassic and Jurassic sandstone populate a n
Apartment buildings made of sandstone from the late Triassic and early Jurassic periods shelter us and comprise some of the most visual environments in New York City. This sandstone is the result of a 200-million-year journey that began when dinosaurs first started to evolve. Blocks carved from what remains of the world of dinosaurs—some housing fossils and dinosaur footprints—create the city's iconic "brownstones." We co-habitate with stone that was once sandy mud trampled by the feet of dinosaurs.

Hydrocarbons: fossilized organic matter, capable of being made into plastics and fuels
New York City taxis are primordial bodies on the move, from the paint that coats their exteriors down to the fossil fuels that power them. A synthetic paint color named DuPont M6284, or "taxi yellow," adorns all NYC taxis....[More]
Hydrocarbons: fossilized organic matter, capable of being made into plastics and fuels
New York City taxis are primordial bodies on the move, from the paint that coats their exteriors down to the fossil fuels that power them. A synthetic paint color named DuPont M6284, or "taxi yellow," adorns all NYC taxis. It is a hydrocarbon amalgamation derived from crude oil that was millions of years in the making. It is the transformed remains of animals and plants that lived in the Devonian, Cretaceous and Permian periods.

Fumarole: a vent that emits hot gases, usually associated with activity of Earth's magma
Vaporous exhalations rising from manholes signal the presence of a powerful subterranean beast: the world's largest commercial steam system. Made from paleowater heated by fossil fuels, the steam is channeled through a labyrinth of buried pipes, heating more than 100,000 establishments....[More]

Vaporous exhalations rising from manholes signal the presence of a powerful subterranean beast: the world's largest commercial steam system. Made from paleowater heated by fossil fuels, the steam is channeled through a labyrinth of buried pipes, heating more than 100,000 establishments. Sinuous clouds billow from manholes for various reasons, including vaporization of rainwater that comes into contact with the system's pipes.

Resource Extraction: the removal of valuable minerals or other geologic materials from an ore body,
Jumbled heaps of metal found in scrap yards can be seen as composed of time travelers that have converged on the planet from unknowable points in deep space. Copper, common to scrap yards, is one of the 94 naturally occurring elements on Earth. It and other elements were formed by various cosmic processes involving supernovae, nucleosynthesis, nuclear fission, alpha decay and cosmic-ray spallation. Later, some of these elements coalesced to form Earth itself. At the scrap yard, geologic transmutation that began billions of years ago continues.

Moraine: a mound of unsorted till, deposited by ice action or melting of a glacier
Up to 215,000 metric tons of salt from the Chilean desert are heaped into piles each year at various storage facilities throughout the city, resulting in 44 desert moraines....[More]
Moraine: a mound of unsorted till, deposited by ice action or melting of a glacier
Up to 215,000 metric tons of salt from the Chilean desert are heaped into piles each year at various storage facilities throughout the city, resulting in 44 desert moraines. These Miocene epoch–aged tons of crystallized time mix with fresh snow and quietly dissolve into meltwater on their way to sewer drains.

Rich Seam: an underground layer of a valuable mineral waiting to be found
In the past 170 years, New Yorkers have lovingly tucked the bones of nearly 600,000 people beneath the glacier-carved hills of Brooklyn's Green-Wood Cemetery. Given the cemetery's current population, more than 655,000 kilograms of calcium have come to rest within its serene Pleistocene epoch landscape.

Dear Sir, Urban Geology seems to be very useful for survival of all the species living on this plant.Your comments and way of viewing things that formed and existed around the spots of urban areas connected to geology look creating a new thinking pattern to save our outer crust at least.In Sri Lanka we see unknown forces with friendly environment gather people around these rock-carved religious monuments.Money as well as many kinds of sources stacking on this places with unseen forces.May be due to geological activities since thousands or millions of years without doing any harm in mass scale for pilgrims.Still we visit and study them.I believe planet's outer crust had have particular spots that always try to keep friendly atmosphere with geology and theology.My best for Scientific American.

Why urban only? This applies to all environments.
