 ... the following rules may be taken as a rough guide: 1. Massive or crystalline rocks, such as granite, gneiss and schists, will transmit water less freely than those of sedimentary origin. • 2. Stratified rocks will transmit water much more readily...  Waterways and irrigation - Page 6831916Full view - About this book
