Strange, tiny structures have been found in the rocks around the deserts of southern Africa and the Arabian Peninsula.

In the desert areas of Namibia, Oman, and Saudi Arabia, research work has revealed unusual structures that are probably due ...

Mysterious tunnels in desert rocks may be the work of unknown microbes, hinting at a hidden world inside marble and limestone ...

It is assumed that microorganisms may have bored the tunnels to use nutrients present in the calcium carbonate, the main component of marble. The fine powder remained behind. Passchier also found ...

One of the most common chemicals connected to calcium is called “carbonate”, and together they make calcium carbonate. Calcium carbonate is in eggshells, seashells, a rock called marble, and in ...

The discovery has sparked interest among scientists studying endolithic microorganisms, unknown life forms inside rocks.

Led by Balqees bint Nasser al Khayaliyah, Maiyar bint Ahmed al Jahwariyah and supervised by Dr Amal bint Salim al Rahbiyah of the University of Technology and Applied Sciences-Muscat, the research ...

In the vast and arid landscapes of Namibia, Oman, and Saudi Arabia, a team of researchers has identified a series of peculiar structures in marble and limestone formations, whose origin does not seem ...

The making of stone paper involves the process of grinding leftover mined marble into a fine powder, adding calcium carbonate and a resin mixture and bringing it to boil at around 160 degrees ...

Millions of shells of tiny sea creatures fell to the ocean floor after death. Compaction built up all these Calcium Carbonate shells into a 'blocky' rock called Carbiniferous Limestone.

Whilst the rate of reaction can be investigated in several ways there are typically three classic experiments used with students. These are the reactions between: calcium carbonate (marble chips) and ...
