🇮🇳🚩🇮🇳 ITACOLUMITE 😘:- the flexible sandstone or quartzite from the WONDERLAND INDIA @ GEOLOGICAL MUSEUM IIT (ISM) DHANBAD with Dr. P. R. Sahoo (Assistant Professor) Dep. Of APPLIED GEOLOGY & ADI GEO DHANBAD ⚒️ 🙏. Itacolumite is a naturally occurring porous, yellow sandstone that is flexible when cut into thin strips. It was first reported from Mt. Itacolumi in the southern portion of Minas Gerais, in Brazil (hence named Itacolumite, after locality of its first reporting) .
Itacolumite is known from various countries, namely, Brazil, USA, FRANCE, MADAGASCAR AND INDIA etc. In India, itacolumite is known from Penganga, Maharashtra, Raj Nandgaon, Chhattisgarh , Jabalpur, Madhya Pradesh and Kaliana, Haryana.
🤔Reasons for the flexibility of itacolumite :- (1) mineralogical composition (e.g. presence of clay Min. as Kaolinite & mica..) and (2) presence of intergranular void spaces among Quartz grains.
