Introduction

This standard is for plains, basins, tidal flats, coastal waters, lakes, wetlands, grasslands, loess plateaus and hilly mountains developed in China's Quaternary. Developed by regional, basic resources and environmental geochemical surveys conducted in the regions. Multi-target regional geochemical survey specification (1.250000)

1 Scope

This standard specifies the nature of the multi-target regional geochemical survey work, the purpose of the task, the design of the design book, the field work method, the analysis refers to Standards, sample testing, abnormality verification and evaluation, quality management, drawing compilation and report preparation. This standard is applicable to the development of multi-target regional geochemical surveys in the Quaternary developmental areas and coastal waters of China.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Multi-target regional geochemical survey multi-purposeregionalgeochemicalsurvey The basic geological survey work carried out in the Quaternary development zone is mainly based on soil geochemical measurements, and near-shore seabed sediment measurements and The sediment measurement at the bottom of the lake is supplemented by a systematic investigation of the characteristics and spatial distribution of elements and compounds, and the development of basic geology and land resources. Applied research on sources and ecological environment. 3.2 Geochemical survey of sediments in coastal waters. coastlinemarinesedimentgeochemicalmeasurement The system collects nearshore seabed sediments, systematically investigates the content and spatial distribution of elements and compounds, and develops the basic land. Applied research on quality, land resources and ecological environment. 3.3 Lake sediment geochemical survey lakesedimentgeochemicalmeasurement The system collects the sediments at the bottom of the lake, systematically investigates the characteristics and spatial distribution of elements and compounds, and conducts basic geology and Applied research on soil resources and ecological environment. 3.4 Soil geochemical reference value soilgeochemicalbaseline The magnitude of the soil geochemical background is reflected in the geochemical characteristics of deep soil within a certain range. 3.5 Soil geochemical background value soilgeochemicalbackgroundvalues The magnitude of the geochemical background of the soil reflects the geochemical characteristics of the surface soil within a certain range.
