摘　　要：本文应用XRD测试技术和岩石地层学方法、生物地层学方法,将即墨温泉地热区第四系划分为层Ⅰ、层Ⅱ1、层Ⅱ2和层Ⅲ,根据沉积物中所含石膏、岩盐等与温泉地热水相关的自生矿物的空间分布和以直隶小旋螺(Gyraulus chihliensis)为代表的腹足类陆生软体动物化石,以及以土星介(Illyocypris sp.)为代表的节肢动物介形虫化石的空间分布,确立Ⅱ1层为温泉喷流沉积,是第四纪活动断裂控制的地球化学异常的产物,以此建立起温泉喷流沉积模式。The Quaternary deposits are divided into Layer I, Layer II1, Layer II2 and layer III by means of XRD determinnation, stratigraphy and biostratigraphy. According to the spatial distribution of autogenetic minerals (gypsum and salt rock), Quaternary cmollusa (Gyraulus chihliensis)and microfossils( Illyocypri s sp. )in the sediments and the spatial distribution of these sediments, Layer II1 is considered to be the eruptive flow sediments of the warm spring formed through the erosion, transportation and deposition of Layer I and Layer II2 under the action of high mineralized thermal water at the eruptive flow area of the warm spring. According to spatial distribution of the sediments, the depositional model of the sediments in Jimo warm spring is established.
