The radiolarian chert rocks are one of the most important indications of the existence of ophiolites because they are a source of silica supply.These rocks have been studied to refute and reject the idea that ophiolites do not existed.The Si/(Si+Al+Fe+Ca) ratio in the radiolarian chert indicates that the silica is of biogenic origin and adds SiO2 f… Read More
