Sediment‐hosted gold (SHG) deposits are becoming more widely recognized in the Southeast Asian region. They are characterized by very fine‐grained gold, typically occurring in stratabound jasperoid replacement and structurally controlled orebodies in calcareous or carbonaceous sedimentary rocks, which are commonly distal to porphyry copper–gold deposits. Gold mineralization is associated with anomalous As‐Sb‐Hg‐Tl and is normally concentrated in the arsenic‐rich rims of pyrite and arsenopyrite grains (commonly refractory). The examples discussed in this paper are located in Southeast Asian countries, and all occur in island or continental arc terrains. SHG deposits have many features comparable to the Carlin deposits in Nevada; however, they differ in tectonic setting, their shallow level of emplacement, fluid composition, and probable metal source. As such, the Southeast Asian examples described in this compilation may be classified as “Carlin‐like” but not “Carlin‐type.” Furthermore, they appear to represent a subclass of low‐temperature epithermal deposits, with most occurrences showing late‐stage colloform quartz vein events. Indeed, they are better described as sediment‐hosted epithermal gold deposits.

沉积物在东南亚的金矿床

沉积物托管的金（SHG）矿床在东南亚地区得到越来越广泛的认可。它们的特征是金的粒度非常细，通常出现在钙质或碳质沉积岩中，通常位于斑岩型铜金矿床的远处，在地层约束的碧玉置换和结构受控的矿石中发生。金矿化与异常的As-Sb-Hg-Tl有关，并且通常集中在富铁的黄铁矿和毒砂晶粒（通常是难处理的）边缘。本文讨论的示例位于东南亚国家/地区，并且都发生在岛屿或大陆弧形地形中。SHG矿床具有许多与内华达州Carlin矿床相当的特征；然而，它们在构造背景，浅埋入水平，流体成分，和可能的金属来源。因此，本汇编中描述的东南亚示例可能被归类为“类卡林”，而不是“类卡林”。此外，它们似乎代表了低温超热沉积的一个子类，大多数事件都显示了晚期共沸状石英脉事件。确实，它们被更好地描述为沉积物超热金矿床。
