How are the Pindus Mountains formed?
The Pindus Mountains are located on the mainland of Greece. This mountain range was formed due to the succession of cretaceous and Jurassic limestone.
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

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.

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.
How are the Pindus Mountains formed?

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?

The period after the Cretaceous is the Paleogene period, which is part of the Cenozoic era. It includes the Paleocene, Eocene, and Oligocene epochs.
