Is Granite A Good Aquifer

An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.

Is granite a good aquifer.

An aquifer is a body of saturated rock through which water can easily move. Other rocks can be good aquifers if they are well fractured. Aquifers must be both permeable and porous and include such rock types as sandstone conglomerate fractured limestone and unconsolidated sand and gravel. Unconsolidated and semiconsolidated sand and gravel aquifers sandstone aquifers carbonate rock aquifers aquifers in interbedded sandstone and carbonate rocks and aquifers in igneous and metamorphic rocks.

A very dense granite that will yield little or no water to a well may be exposed at the land surface. Unconsolidated materials like gravel sand and even silt make relatively good aquifers as do rocks like sandstone. This sandy soil cover on or fracture fill in granite and gneiss too serve well as a good aquifer. Aquifers can also be found in regions where the rock is made of denser material such as granite or basalt if that rock has cracks and.

Further the granite and gneiss bear fractures and joints serving directly as voids for groundwater or filled with the sandy soil derived in situ. Fractured volcanic rocks such as columnar basalts also make good aquifers. The principal water yielding aquifers of north america can be grouped into five types. Aquifer types geologic materials can be classified as consolidated rock or unconsolidated loose sediment.

Would be considered an aquifer or aquaclude but. I was trying to search wheather or not those rocks. Consolidated rock may consist of such materials as sandstone shale granite and basalt. Till outwash sandstone shale limestone and granite.

Paleozoic through cenozoic age sandstones that extend northeastward from wyoming form the northern great plains aquifer system which has permeable parts of more than 2 000 meters thick in some places in a deep structural basin. Unconsolidated sediment contains granular material such as sand gravel silt and clay. The saturated zone beneath the water table is called an aquifer and aquifers are huge storehouses of water. What you are looking at in this picture is a well that exposes the water table with an aquifer beneath it.

Photograph shows carbonate rocks of the northern great plains aquifer system. For example the ogallala aquifer a vast. There s no useful site that would help me d. Unconsolidated materials like gravel sand and even silt make relatively good aquifers as do rocks like sandstone.
