地质流体与流体地质填图

地质流体是地质作用过程不可缺少的介质，以不同产状和表现形式广泛发育在造山带和沉积盆地的不同演化阶段，是油气和成矿物质形成、运移和定位成矿（藏）的直接载体。流体地质填图作为一种专题地质填图，是在基础地质研究程度较高的地区，为解决与流体形成、运移、聚集过程有关的地质和成矿（藏）问题而进行的地质调查和填图工作。通过对流体地质特征和表现形式的论述，认为流体填图单位应以流体活动类型（同源）和期次（同期）为划分依据，以流体野外宏观地质要素和流体地球化学要素为主要调查内容，填图范围和比例尺灵活多样，成果图应为以反映流体宏观分布特征、流体地球化学性质变化、流体动力学、流体成矿（藏）作用及其分布规律等为内容的一系列图件。流体地质填图为地质科学研究和找矿提供了创新性的地质工作方法和思路。

Geofluid and geological mapping for geofluid

Geofluid played an indispensable role in almost all geological processes and was widely developed in different evolutionary stages of orogeny and sedimentary basin with different occurrences and various forms. Geofluid is considered to be the direct carrier of oil/gas or metal to form reservoir or deposit by migration and accumulation. The aim of geological mapping for geofluid is to solve special geological problems related to geofluid or to investigate natural resources formed along with geofluid formation, migration and accumulation. This paper discusses basic issues of geological mapping for geofluid for detecting features and forms of geofluid both in field outcrop and under microscope. It is proposed that the unit of geological mapping for geofluid should be divided by source and episode of geofluid itself. The essential work of geological mapping for geofluid is mainly to investigate geological features in field outcrop and determine geochemistry of the geofluid. The scale and scope of geologic mapping for geofluid could be flexible and be dependent on the aim and task of the work. Map representation should be a series of maps to reflect field distribution characteristics, variation of geochemistry, geodynamic history, active pathway and mineralization of geofluid. Geological mapping for geofluid provides new methods and ideas for geological research and prospecting work.
