Aquifer means a subsurface layer or layers of geological strata of sufficient porosity and permeability to allow either a flow of or the withdrawal of usable quantities of groundwater.

The Geological Survey provides geological information and assistance.

Aquifer means a subsurface layer or layers of rock or other geological strata of sufficient porosity and permeability to allow either a significant flow of groundwater or the abstraction of significant quantities of groundwater.

It's like a geological conveyer belt

A zone includes strata characterised by the overlapping range of fossils.

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

The principle is important to the analysis of folded and tilted strata.

In particular, it sought to protect the most vulnerable strata of society.

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.

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

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

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

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

An increase was observed in housing construction. However, this particularly benefited the highest social strata.

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

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

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

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

Therefore, stages can be defined as a group of strata containing the same major fossil assemblages.

Rising sea levels would explain a lot of geological and economic events.

He works for the US Geological Survey (USGS) in Menlo Park, California.

25. The geological model of the area is well known and documented (see paras. 10 22). The evaluation of geological studies has concluded that, although boring a tunnel through the subaqueous rocks should not face major geological problems, the knowledge of those rocks has to be significantly improved.

Identify potentially toxic overburden or exposed strata and screen with suitable material to prevent mobilization of toxins

The incitement to hatred, violence or discrimination between social strata is equally prohibited and punishable by law.

There was no denying that its consequences for the poorest strata of the population must be checked.

This is confirmed in part by figures from the United States Geological Survey.

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

Though average family size has decreased, that decrease is not evident in the lowest strata of the population.

Regarding the right to housing, a rebound in construction has been observed, but largely to the benefit of social strata 4, 5 and 6, whilst for social strata 1, 2 and 3, insufficient availability of house ownership and limited access to subsidies persisted.

Inorganic compounds are traditionally viewed as being synthesized by the agency of geological systems.

The share was originally held by the French Government's mining and geological research department.

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

Other activities in natural disaster reduction have focused on water related and geological hazards.

The Greensat could be used for geological surveys, environmental management and natural disaster assessments.
