after Jurrasic period it is the Cretaceous period
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
What is the main substance in limestone?
The main substance in limestone is calcium carbonate.
Is limestone magnetic?
No, the limestone is not magnetic due to the magnetic fields in the stone itself.
What is cretaceous stone?
A common Cretaceous stone found in some parts of the world is a limestone we know as chalk.
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.
What is the Acropolis made out of?
The Acropolis is late Cretaceous limestone, and it's part of a ridge of this material that cuts through the area.

Where does the pure white color of limestone come from?
There are different types of limestone rock in the UK which differ in colour. Carboniferous limestone is greyish and hard and made from the remains of corals. Jurassic limestone is yellowish and softer. It is oolitic (made from little eggs of calcite). Cretaceous limestone is very white and chalky. It is made from the skeletal remains of planktonic organisms.
When was the cretacous period?
Cretaceous PeriodThe Cretaceous was about 145 million to 66 million years ago. The Cretaceous gets its name from the latin word for chalk, creta, because it includes the layers of this distinctive pure white limestone. It is the last period of the Mesozoic ("middle life") Era.
What county in Ireland has no limestone?
Wicklow in the Republic of Ireland and Antrim in Northern Ireland.
What stone is the Acropolis made out of?
The Acropolis is late Cretaceous limestone, and it's part of a ridge of this material that cuts through the area.
When was Cretaceous Research created?
Cretaceous Research was created in 1980.
Did the dinosaurs died at the end of the cretaceous Jurassic or triassic period?
Cretaceous.
What type of landforms were in the cretaceous time period?
There was a lot of chalk because a large area of the continents was covered by warm shallow seas, as a result of that there was a lot of marine limestone. You can also find chalk with many types of algae that flourished during the cretaceous period. An example of a landform would be the white cliffs of dover. There are also landforms in Sussex, the isle of Wright and East Dorset
What period was after the cretaceous?
The Paleogene Period followed the Cretaceous.
