Gyrolite

Extract
The mineral gyrolite was discovered in Skye by T. Anderson in 1851. He showeditto be ahydratedcaleiumsilicateofapproximate composition 2CaO.3SiO2.3H2O. Subsequently gyrolite has been found in other localities, and has been prepared hydrothermally by Flint, McMurdie, and Wells. The ratio of lime to silica found by Anderson appears well established, but various values of the water content have been reported and more recent analyses approximate to 2CaO.3SiO2.2H2O. X-ray powder measurements were given by McMurdie and Flint, a but no crystallographic or other investigations of a detailed character have been reported.
