Lassi Korhonen,Keijo Ruotsalainenare controlled partly by the environment of deposition. In the same way, the maximum grain size, grain-size distribution, fabric, etc., are also controlled by the hydrodynamic conditions existing at the time of deposition. There have been repeated attempts to use such grain parameters as environment革新 发表于 2025-3-28 22:18:43

Anne Bouillard,Claude Jard,Aurore Junierlizations regarding distribution of bedding types are made. However, the critical reader is referred to Part I, where their distribution and genesis have been described. The utility of such models would be proved by critical study of such models in the light of study of ancient environments.领巾 发表于 2025-3-29 03:13:35

Introductionlithosphere by volume, they occupy 75% of the exposed land area (Pettijohn 1957). Thus, the study of sedimentary rocks is the major problem of geology. An obvious question arises in the study of sedimentary rocks: Under what conditions and by which processes were the sedimentary rocks in question deposited.巧思 发表于 2025-3-29 22:28:42
Physical Parametersnd textures of a sediment are the major features that provide information about the medium and mode of transport (by ice, water, or wind) and energy conditions at the time of deposition. Energy conditions include depth of water, velocity of flow, turbulence, wind velocity, etc. The study of physical parameters can be divided into two groups.Petechiae 发表于 2025-3-30 01:19:45
