Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper analyzes the increasing global demand for mineral resources, particularly non-ferrous metals, and the growing challenge of finding new deposits as easily accessible ones are depleted. The study focuses on copper-porphyry deposits, which are crucial for meeting this demand. It highlights the importance of improving exploration methods and integrating various geological, geophysical, and geochemical techniques. The research emphasizes the unique metallogenic potential of Kazakhstan, specifically the Dzungar-Balkhash folded region, which hosts significant copper deposits like Kounrad, Bozshakol, Koksai, Aktogay, and Aidarly. The study uses the Koldar massif as a reference site to analyze the geological and mineralogical characteristics of these deposits. The methodology involved field studies, sample collection, and macro- and microscopic mineralogical analysis. A key finding of the study is the identification of widespread kalishpatization and argillitization zones within the Kyzylkiya deposit, which were confirmed through both spectral analysis and micromineralogical studies. The research also details the mineralogical and geochemical characteristics of different types of copper-porphyry ores, linking them to specific petrological features of the ore-bearing plutonism. The paper concludes by presenting prospect and prospecting signs for copper-porphyry deposits in various geological settings.
