前言本文主要探讨了有关沉积相、岩相的概念、分类、研究意义和研究方法,并列举了在矿产的予测、普查勘探中的应用实例。一、沉积相、岩相的概念最早把“相”这个术语用于地质文献是在1669年,丹麦地质学家斯丹诺(N.Steno),他认为:“相”是“时期”和“阶段”的意思。也就是说,“相”是地质年代的单位。瑞士地质学家格列斯利(A.Gressly)在1847年,把“相”用于沉积岩石学中。他 Preface This paper mainly discusses the concepts, classification, research significance and research methods of sedimentary facies and lithofacies, and also lists some examples of application in mineral prospecting and census exploration. First, the concept of sedimentary facies, lithofacies The term “facies” was first used in geological literature in 1669 by Danish geologist N.Steno, who argued that “facies” is “period” and “ Stage ”means. In other words, “phase” is the geologic age unit. The Swiss geologist A. Stressly used “facies” in sedimentary petrology in 1847. he
