I. Project Basic Information

1、Secondary Project Name: Multiscale Geochemical Mapping and Integrated Application in Southeast Asia and Central Asia

2、Primary Project Name: Basic Public Geology and Mineral Survey

3、Project Leaders: Wang Xueqiu, Nie Lanshi

4、Responsible Organization:Institute of Geophysical and Geochemical Exploration, Chinese Academy of Geological Sciences

5、Project Duration: 2016-2018

II. Overall Objectives and Tasks

Relying on the UNESCO Global Geochemical International Research Center, this project focuses on multiscale geochemical mapping along the "Belt and Road" initiative. The goal is to establish a global geochemical baseline network covering one-fifth of the Earth's land area and create a global geochemical map platform. The project will compile geochemical maps of key metallogenic belts along the "Belt and Road" and integrate geochemical data for potential evaluation of major minerals such as copper, gold, uranium, platinum group elements, and rare earths. This will provide a decision-making basis for resource planning along the "Belt and Road" and offer follow-up mineral exploration areas (at least five) for enterprises.

III. General Work Content

1、Establishment of a Global Geochemical Baseline Network and Resource-Environmental Comparative Analysis

Relying on the Global Geochemical International Research Center, a multiscale geochemical mapping technical guideline will be developed. Geochemical mapping training and quality control will be organized for foreign projects. The project will focus on multiscale geochemical mapping along the Belt and Road, establishing a geochemical baseline network covering one-fifth of the Earth's land area. Global geochemical maps will be gradually drawn, with resource and environmental analysis and comparison conducted in mapped areas.

2、Geochemical Mapping and Dynamic Monitoring of Major River Estuaries

Geochemical samples will be collected from major river estuaries and their tributaries worldwide, with analysis of 76 elements. A global geochemical map of river estuaries will be preliminarily drawn, and a global geochemical dynamic monitoring network will be established.

3、Geochemical Mapping and Resource Strategic Target Area Prediction in China, Mongolia, Russia, and Kazakhstan

Geochemical data from China, Russia, Kazakhstan, and Mongolia will be systematically collected, and additional sampling will be conducted. A preliminary 1:5 million geochemical map or anomaly map will be created for China, Mongolia, Russia, and Kazakhstan. A 1:1 million geochemical map will be completed for the remaining 470,000 square kilometers in cooperation with Mongolia, and collaboration with geological survey organizations and enterprises will be undertaken to guide mineral exploration both domestically and internationally.

4、Geochemical Mapping of the Tethys Metallogenic Belt and the Middle East, Iran, Turkey, and Pakistan Economic Corridor

Data on the geochemical mapping of the Tethys Metallogenic Belt will be collected, with a focus on geochemical mapping cooperation with Iran, Turkey, and Pakistan. A 1:5 million geochemical map of the Middle East, Iran, Turkey, and Pakistan Economic Corridor will be compiled, comparing geochemical characteristics and trends to provide foundational geochemical data for the development of the Silk Road economic zone.

5、Low-Density Geochemical Mapping Cooperation between China and Laos

Through cooperation with Southeast Asian countries on low-density geochemical mapping, the geochemical mapping level of Southeast Asia will be improved. A geochemical mapping guideline for Southeast Asian countries (CCOP/ASEAN) will be developed, and geochemical mapping training for CCOP and ASEAN member states will be conducted. The 1:1 million geochemical map of Laos will be completed, covering 69 elements.

6、Global Multiscale Geochemical Mapping Results Integration and Compilation of a Unified Map

Comprehensive research will be conducted on the global multiscale geochemical mapping results. A global database will be created by collecting and integrating previously completed global geochemical mapping data and newly obtained data. A "Chemical Earth" platform, similar to Google Earth, will be established, and a unified global geochemical map will be compiled.
