以杰尔图拉克矿化特征为例研究了阿穆尔河流域碳酸盐岩中金的成矿作用 ,并将碳酸盐围岩和矿石与美国内华达州卡林金矿床进行了地球化学和岩石化学的比较分析 .查明了含有粘土—水云母 (K、Al)组分及多种成矿元素的白云岩的矿化富集趋势 .矿体为条带状或角砾状白云岩 ,它具有脉状金—多金属、透镜状金—磁铁矿—磁黄铁矿及浸染状金—黄铁矿—毒砂等矿化 .矿化在碳酸盐岩层剖面中占据一定的层位 .矿石特征是金以不同粒度的、成色高的游离金存在 ,并与辰砂共生 .杰尔图拉克矿床金—黄铁矿—毒砂成矿作用与卡林型金矿床相似 ,特别是与乌拉尔的沃龙佐夫矿床碳酸盐岩金矿石相似 .总结了阿穆尔河流域碳酸盐岩地层中金矿的找矿远景 .
Taking the mineralization feature of Gyur Turak as an example, the gold mineralization in Carbonate rocks in the Amur River Basin has been studied and the carbonate rock and ore have been geochemically and petrochemically studied with the Carlin gold deposit in Nevada, USA The trend of mineralization and enrichment of dolomite containing clay-water mica (K, Al) and various ore-forming elements was identified.The ore body is a banded or brecciated dolomite with Vein gold - polymetallic, lenticular gold - magnetite - pyrrhotite and disseminated gold - pyrite - arsenopyrite, etc. Mineralization occupies a certain horizon in the profile of the carbonate rock ore The feature is that gold exists in free gold with different grain sizes and high quality and coexists with cinnabar.The gold-pyrite-arsenopyrite mineralization in the Gyrturra deposit is similar to the Carlin-type gold deposit, especially with the Urals The Dragonfold deposit is similar in carbonate gold ore, and the prospect of prospecting for gold deposits in Carbonate strata in Amur Basin is summarized.
