GB/T 42637-2023Specification for oceanic polymetallic sulfide resources survey (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

Introduction

Over the past ten years, a series of solid mineral exploration standards, laws and regulations have been promulgated both internationally and domestically, including the "Deep State of the People's Republic of China" Seabed Area Resources Exploration and Development Law", "Classification of Solid Mineral Resources and Reserves" (GB/T 17766-2020), "Regulations for Geological Exploration of Solid Minerals" "General Regulations" (GB/T 13908-2020), "International Reporting Template for Public Reports on Exploration Targets, Mineral Resources and Ore Reserves" (November 2013 version), the International Seabed Authority Standards for the Assessment of Mineral Exploration Targets, Mineral Resources and Mineral Reserves Reporting and the Standards for Polymetallic Sulphides in the Area Prospecting and Exploration Regulations (hereinafter referred to as the Regulations), etc. In the past 40 years, my country has carried out exploration of solid mineral resources on the international seabed, except for "Ocean Regulations for Exploration of Polymetallic Nodule Minerals (GB/T 17229-1998), Specifications for Exploration of Oceanic Polymetallic Nodule Resources (GB/T 35571-2017), "Oceanic Cobalt-rich Crust Resource Exploration Specifications" (GB/T 35572-2017), there is no relevant oceanic polymetallic sulphide resource exploration. specification.

The "Regulations" promulgated and implemented by the International Seabed Authority divide the exploration activities of international seabed polymetallic sulphide resources into two stages. prospecting and exploration. stage, where the prospecting stage is the investigation activities carried out by the contractor before obtaining the exploration contract, and part of the investigation work will also be carried out in the early stage of the exploration stage.

The exploration phase refers to the exploration activities carried out by the contractor in the contract area for the commercial development of minerals. At the same time, depending on the degree of exploration The exploration stage is further divided into general exploration and detailed exploration. As the contractor of polymetallic sulphide mineral resources in the international seabed area, the proposed The relevant reports submitted shall comply with the relevant standards of the International Seabed Authority. In addition, the "Resource Exploration and Development of Deep Seabed Areas of the People's Republic of China" In the meaning of terms in Article 27 of Chapter VII of the Law, the activities in the early stage of deep sea resource exploration are defined as "resource investigation". The resources of this document The source investigation stage is equivalent to the general survey stage in the "General Rules for Geological Exploration of Solid Minerals" (GB/T 13908-2020), which is equivalent to but not limited to Prospecting phase in the Regulations. This document divides the stage of resource investigation into three steps. prospect area investigation, mineralization area investigation and exploration target area investigation.

These steps are applicable to the first stage of mineral exploration, and can be extended to exploration specifications when the practical experience in the later stage matures. Specifications for investigation of oceanic polymetallic sulphide resources
