Where is sandstone mined?
Sandstone is typically mined in very dry places. For example, the Sahara desert is one of the most known areas where sandstone is mined. This is because the Sahara produces sand sized minerals.
In some areas limestone is found underneath the soil. In these areas water can wear away limestone and sinkholes may form on the surface. What is responsible for the formation of sinkholes?
physical weathering
What is upper and lower indus basin?
Lower Indus basin:Sulaiman Range and areas to the south constitute prolific gas producing habitat where Dhodak, Rodho, Sui, Pirkoh, Zin, Loti fields in the north, and in the plains Qadirpur, Kandhkot fields are gas producers. These fields produce from Sui Main Limestone (SML, Eocene), Ranikot sands, Dungan limestone (Paleocene) and the Pab sandstone (Late Cretaceous). In Kirthar Range again Sui Main limestone and mostly Pab sandstone is the reservoir. These regions are part of the Indus basin. Badin area and northern part of Sindh province also fall in Indus Basin where Lower Goru Sands (Lower Cretaceous) are the main reservoir for oil and gas. In all these areas, Sembar shales are considered as the source rock. Habib Rahi limestone (Eocene) is the gas reservoir in the giant Mari Field. Ghazij shale is the cap rock for SML while Ranikot shale provides cap rock for Pab. The intraformational shale within Lower Goru provides the seal.In Punjab Platform area the Jurassic Samana Suk formation (Jurassic) and Lumshiwal sandstone (Cretaceous) are the main gas reservoir, where source rock has not been clearly defined. Chicali shale (Lower Cretaceous) provides cap-rock for the reservoir.Upper Indus basin:In Koht-Potwar, where mostly oil is found, the proven reservoirs are Muree formation (Miocene), Sakesar limestone (Eocene), Hangu and Lockhart (Paleocene), Lumshiwal sandstone (Cretaceous) Datta sandstone (Jurassic), Wargal formation and Tobra formation (Permian)and Khewra sandstone (Cambrian). The source rock in Kohat area is probably Chichali formation (Lower Cretaceous), and in Potwar, Patala shale (Paleocene) is considered as the source rock
Are areas of alluvial fans found where groundwater erodes limestone to form valleys sinkholes and caverns?
no
How much is the price per ton of limestone?
The average cost of a ton of crushed limestone is between $27.50 and $38.20. The cost varies in different areas dependent upon the availability of limestone in that area.
What the relationship between groundwater and precipitation?
In limestone and sandstone areas, especially, ground water filtering through the rock and dissolving the limestone or sandstone, creates potholes, caverns and caves.
Would you have a land fill on limestone and sandstone?
both limestone and sandstone are highly permeable to water. As there are often toxic substances which leak from landfill, it is necessary to collect water which falls on the heap. For this reason, permeable rocks like limestone and sandstone are not the ideal basement for a landfill, and may require significant infrastructure to prevent contamination of the water table below the landfill. They are ideal landfills if the need is there for drainage. Permeable rock has many uses in landfill. Landfill in areas that are naturally high in limestone or sandstone content would have no issues with a little more of either material in it.
Which is missing in most areas that do that do not have karst topography?
Limestone
Where is sandstone mined?
Sandstone is typically mined in very dry places. For example, the Sahara desert is one of the most known areas where sandstone is mined. This is because the Sahara produces sand sized minerals.
Why are limestone caves so common?
Because limestone uplands with appropriate internal geology and surface drainage in areas of long-term, suitable climatic conditions are so widespread. Not all limestone areas support caves though.
Do limestone from areas where shelled sea creatures are highly abundant contain more carbonate or not?
Yes, limestone from areas where shelled sea creatures are highly abundant typically contains more carbonate. Shelled sea creatures like mollusks and corals have shells made primarily of calcium carbonate. Over time, as their shells accumulate and get compacted, they form limestone. As a result, limestone from these areas will have a higher carbonate content compared to limestone from areas without such abundant sea creatures.
What type of rock is usually present in areas with a lot of caves?
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
In some areas limestone is found underneath the soil. In these areas water can wear away limestone and sinkholes may form on the surface. What is responsible for the formation of sinkholes?
physical weathering
Is limestone easily accessible?
In some geographical areas, yes. In other areas, no. It depends on the geology of the area.
What areas had a high concentration of limestone from 1890-1920?
northern Michigan
What type of rock is usually present in areas with lots of caves?
limestone
Why does the US have large areas of limestone?
During the Cretaceous period much of the interior of the United States was covered in a warm, shallow sea, which is conducive to the formation of limestone.
