| Mineralogical Symptoms of Warm Spring Sedimentation and Researches on Depositional Facies in the Jimo Warm Spring, Qingdao |
| Based on field sampling,XRD data and mineralogical symptoms of warm spring sedimentation,the authors divided the warm spring sedimentation into eruptive-flow depositional facies,leaky depositional facies and vent-channelway depositional subfacies,and described in detail the basic concept,the formation mechanism,and the depositional model for warm spring sedimentation.Mineralogical symptoms of the eruptive-flow depositional facies and the vent-channelway depositional facies are set up,being the series of opal-gypsum-halite-zincobotryogen-hematite.The significance of the above study is reflected in the following aspects:① the defining of the concept of warm spring sedimentation and the division of genetic types of warm spring sedimentation;② the construction of the symptoms in search for hidden warm springs and ancient geothermal activities and the delineation of geothermal centers for guiding the exploitation of geothermal resources;③ the formulation of analogous surroundings for ocean floor hydrothermal sedimentation and ore-forming process. |
