Geological and Geochemical Characteristics of the Pac Lang Gold Deposits, Northeastern Vietnam and Their Potential Prospects

Abstract

The Song Hien Rift basin, located in northeast Vietnam, has been identified as an important region for gold deposits, including the
Pac Lang deposit. Several methods like petrographic observations, elemental analyses, and geochemical elements and vertical zoning
models of primary halo have been used to describe geological characteristic of this deposit. The investigation focused on examining the
geological events that occurred both before and after the formation of the ore. The use of ICP-MS analysis and element concentration
contrast enabled an effective assessment of the relative degrees of denudation that occurred at the Pac Lang deposit. The findings of this
study were consistent with prior research on ore deposit geology, geochemical primary-halo, and examination of geochemical indicator
zoning patterns for gold ore bodies. The study's application of singularity analysis for evaluating the degree of denudation provides
important geological information that can aid in data interpretation. The results of the study can also have significant reference value
in furthering our understanding of the post-ore deformation of deposits and in the investigation of unknown orebodies in northeast
Vietnam. There indicate that, the research's findings suggest that the use of singularity analysis to evaluate the degree of denudation
is a valuable tool for exploring potential gold deposits and enhancing our knowledge of gold deposit geology in northeast Vietnam.
Overall, this study contributes to the existing body of knowledge on gold deposits in the Song Hien Rift basin and can serve as a useful
reference for future research in the area.
