Introduction,is book the concept of Walther (1893/94), based on Gressly and recently reiterated by Murawski (1972), Middleton (1973) and Woodford (1973), is followed, in which facies encompasses all the physical, chemical and biological characteristics of an areally defined geological body in its present state. 作者: 流動(dòng)才波動(dòng) 時(shí)間: 2025-3-23 16:08 作者: 不連貫 時(shí)間: 2025-3-23 21:15
