A formation or geological formation is the fundamental unit of lithostratigraphy.

Is it a geological formation, or a man made bridge?

Aquifer Natural water bearing geological formation found below the surface of the earth.

A permeable geological formation has pores that permit liquids or gases to pass through.

Differences in geological resistance in the same geological formation can lead, over time, to the formation of columns and arches like the ones in Moab, Utah and bridges like the Rainbow Bridge, also in Utah.

(a) Aquifer means a permeable water bearing geological formation underlain by a less permeable layer and the water contained in the saturated zone of the formation

A geological formation consists of naturally occurring materials, either consolidated or unconsolidated, such as rock, gravel and sand.

The permeability of the underlying layer is less (lower) than that of the geological formation in the aquifer.

In order to clarify that the formation can consist not only of rock in common usage but also of other materials, the term geological formation is opted for.

The Geological Survey provides geological information and assistance.

As we are currently dealing only with water and not with oil or gas, a modifier, water bearing , is inserted before the words geological formation .

A. Geological studies

11. The geological studies conducted between 1982 and 1992 naturally took into account the abundant existing literature on the geology of the Gibraltar arc as well as long standing theoretical data and general geodynamic concepts concerning the geological evolution and formation of the region.

The Royal Geological Society?

But the fact is, this is evidence of a living body on other bodies, rocks that have been the subject of geological formation, erosion, the action of time on objects.

Yes, I know. Geological sections...

Many more fossils are still in the ground, in various geological formations known to contain a high fossil density, allowing estimates of the total fossil content of the formation to be made.

It's like a geological conveyer belt

Hold formation.

Formation, turn.

Defensive formation.

Squad formation!

Darwin completed his third geological book in 1846.

Climate changes can influence a planet's geological history.

It was an unambiguous pattern, a geological pattern.

But in geological terms, that is staggeringly fast

In subparagraph (b), the expression each associated with specific geological formations is inserted to indicate that an aquifer system could consist of aquifers not only of the same geological formations but also of different geological formations.

D. Family formation

They're maintaining formation.

Yet, it's 3,000 times tougher than its geological counterpart.

So it's the deepest geological bore hole ever drilled.

Gross fixed capital formation.

Interesting driftwood formation too.

The concept of reserves is technical and economic, not geological.

17 President, International Marine Minerals Society United States Geological Survey.

As you can see here, they collapse from a three dimensional formation into planar formation.

IV. FORMATION OF THE GOVERNMENT

Thus the formation of planetary systems is thought to be a natural result of star formation.

The Mesozoic Era is an interval of geological time from about .

We have no geological record prior for the first billion years.

What explains Earth's past, its geological eras and its ancient creatures?
