Abstract—

The Central Kolyma region is the main gold-bearing part of the Verkhoyansk–Kolyma fold-and-thrust belt. Analysis of the developed geodynamic models of fold and thrust belt formation mechanisms, the Verkhoyansk–Kolyma belt in particular, suggests the leading role of subhorizontal movements on the detachment zone (decollement) at the base of an orogen as the “sole,” on which nappes detached at an early stage and with which major reverse strike-slip listric faults were directly associated at the collisional stage. In our opinion, the role of a detachment fault, the most important regional structure, is obviously underestimated in predictive metallogenic models. The detachment fault zone is complicated by transverse NE-trending faults, where its thickness and the fluid permeability can occur. The paper proposes a variant that links previously discovered gold deposits and occurrences in five gold mineralization strips along the inferred paleofluid flow routes. Here, the paleofluid flow route is the horizontal projection of the most probable migration pathway of released fluids from their generation zone to the ore deposition zone, which is drawn across the largest ore accumulations.

分离断层在科雷马中部地区含矿古流体空间分布中的作用：预测成矿模型的非常规方法

摘要-

中科雷马地区是维尔霍扬斯克-科雷马褶皱逆冲带的主要含金部分。对褶皱和逆冲带形成机制的已开发地球动力学模型的分析，特别是 Verkhoyansk-Kolyma 带，表明在造山带底部的滑脱带（滑脱）上的亚水平运动作为“唯一”，在其上的主导作用。推覆在早期阶段分离，在碰撞阶段与主要的反向走滑断层直接相关。我们认为，在预测成矿模型中，滑脱断层这一最重要的区域结构的作用显然被低估了。滑脱断裂带因NE向的横向断裂而复杂化，其厚度和流体渗透性都可能出现。该论文提出了一种变体，该变体将先前发现的金矿床和沿推断的古流体流动路线的五个金矿化带中的矿点联系起来。这里，古流体流动路径是释放流体从其生成带到成矿带的最可能运移路径的水平投影，该路径跨越最大的矿藏。
