摘要

摘要欧亚大陆北部斑岩系统的金品位较高（0.1-1 克/吨），尽管矿化量通常较小，铜品位较低，但仍可与安第斯斑岩相媲美。结论是，欧亚大陆北部的斑岩系统与西太平洋的斑岩一样，都发生在岛弧环境中，与安第斯大陆岩浆弧相反。论文考虑了欧亚大陆北部斑岩群的结构和构造控制，以及估计斑岩系统侵蚀深度的实际问题。

Porphyry Deposits of Northern Eurasia: Practical Aspects of Tectonic Control, Structural Features and Estimates of Depth of Erosion from the Urals to the Pacific

Abstract

Higher gold grades (0.1–1 g/t) in porphyry systems of northern Eurasia make them competitive with the Andean porphyries despite usually smaller volumes of mineralization and lower copper grades. It is concluded that porphyry systems of northern Eurasia occurred in island arc settings as did the porphyries of the West Pacific, contrary to the Andean continental magmatic arcs. The paper considers structural and tectonic control of porphyry clusters in northern Eurasia, as well as practical aspects to estimate the depth of erosion in porphyry systems.

期刊介绍： Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
