DZ/T 0419.2-2022 - Standards for Evaluation of Mineral Resource Potential (1:250 000) Part 2: Research on the Geological Background of Mineralization

Scope: This document specifies the requirements for the research content, research methods, map preparation and report writing of sedimentation, volcanism, intrusion, metamorphism, large-scale deformation structure and geotectonic phase in the mineralization geological background research work of mineral resource potential evaluation. This document is applicable to the mineralization geological background research in the national, provincial and regional mineral resource (excluding oil and natural gas) potential evaluation work, with a scale of 1:250000 as the main scale, and other related mineralization geological background research can be implemented as a reference.
