Abstract

In the south of the Russian Far East, a new promising type of source of strategic and critically important metals (titanium, gold, platinum, niobium, hafnium, copper, antimony, etc.) has been discovered: these are complex ores and placers that are spatially and genetically related to the Late Mesozoic (Cenomanian?) synorogenic intrusions of ultramafic–mafic rocks of the Sikhote-Alin orogenic belt. One example is the Ariadnensky massif of ultramafic, mafic and granitoid rocks with gold-titanium mineralization in its mafic part, gold-antimony mineralization at the exocontact, and gold-copper mineralization in the circum-intrusive zone. The main mineralogical and geochemical features of these ore formations have been determined. The typomorphic properties of native gold from ultramafic rocks have been revealed. It is shown that mantle and crustal processes were involved in the formation of different types of ore. The materials we obtained provide new opportunities for the reassessment of potential of strategic metal resources in Primorye.

超镁铁质、镁铁质和花岗岩类晚中生代 Ariadnensky 地块（Sikhote-Alin 造山带）的矿石潜力

摘要

在俄罗斯远东南部，发现了一种新的有前景的战略性和极其重要的金属（钛、金、铂、铌、铪、铜、锑等）来源：这些是复杂的矿石和砂矿，在空间和成因上与锡霍特-阿林造山带的中生代晚期（塞诺曼阶？）超镁铁质-镁铁质岩石的同造岩侵入有关。一个例子是 Ariadnensky 地块，由超镁铁质、镁铁质和花岗岩组成，其镁铁质部分有金钛矿化，外接触带有金锑矿化，侵入带周围有金铜矿化。这些矿层的主要矿物学和地球化学特征已经确定。超镁铁质岩石中天然金的标型特性已被揭示。研究表明，地幔和地壳过程参与了不同类型矿石的形成。我们获得的材料为重新评估滨海边疆区战略金属资源的潜力提供了新的机会。
