| 中文摘要:经野外取样和XRD测试技术,根据温泉沉积物的矿物学标识,将即墨Cl-Na型温泉沉积物划分为喷流相、越流相沉积和喷口-通道亚相沉积,并阐述其基本概念、成因以及"盆下源"沉积模式;建立起蛋白石-石膏-岩盐-锌铅铁矾-赤铁矿喷流沉积相和通道-喷口沉积亚相的矿物学标识.上述研究有以下几方面意义:①界定温泉沉积物的概念和划分成因类型;②建立盲温泉与古地热活动寻找标识,圈定地热中心,指导现代温泉地热资源开发;③提供现代海底热水沉积作用、成矿作用的模拟环境. |

| Mineralogical Symptoms of Warm Spring Sedimentation and Researches on Depositional Facies in the Jimo Warm Spring, Qingdao |

| Abstract: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. |
