Is Granite A Good Aquifer

Further the granite and gneiss bear fractures and joints serving directly as voids for groundwater or filled with the sandy soil derived in situ.

Is granite a good aquifer.

Would be considered an aquifer or aquaclude but. The principal water yielding aquifers of north america can be grouped into five types. In wisconsin and adjacent states three cambrian and ordovician age sandstone aquifers are combined into an aquifer system that is as much as 650 meters thick. Aquifers must be both permeable and porous and include such rock types as sandstone conglomerate fractured limestone and unconsolidated sand and gravel.

Other rocks can be good aquifers if they are well fractured. 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. Aquifer types geologic materials can be classified as consolidated rock or unconsolidated loose sediment. A very dense granite that will yield little or no water to a well may be exposed at the land surface.

Fractured volcanic rocks such as columnar basalts also make good aquifers. An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it. 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. 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.

The saturated zone beneath the water table is called an aquifer and aquifers are huge storehouses of water. 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. An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.

Other rocks can be good aquifers if they are well fractured. Unconsolidated sediment contains granular material such as sand gravel silt and clay. What you are looking at in this picture is a well that exposes the water table with an aquifer beneath it. An aquifer is a body of saturated rock through which water can easily move.

There s no useful site that would help me d. Till outwash sandstone shale limestone and granite. I was trying to search wheather or not those rocks. Unconsolidated materials like gravel sand and even silt make relatively good aquifers as do rocks like sandstone.
