The Shwe Min Bon Cu–Au skarn deposit lies within one of the largest Au–Cu belts in Myanmar. The deposit is situated along the Shan scarp zone, which marks the boundary between the Myanmar central basin to the west and the Shan plateau to the east. The Shwe Min Bon deposit comprises skarn‐type metasomatic alteration, and the Cu–Au mineralization occurs along the contact face between the Nwabangyi Dolomite and Shweminbon Formation and the Cretaceous dioritic rocks. The metasomatic process resulted in pro‐ and retrograde mineral assemblages in exoskarn. Hydrothermal activities in the Shwe Min Bon deposit are classified into prograde, retrograde stage I, and retrograde stage II. The prograde skarn is classified into a proximal garnet skarn with minor clinopyroxene and a distal wollastonite skarn. Chlorite, epidote, and tremolite–actinolite were formed during the retrograde stage I. Cu–Au mineralization mainly occurred in retrograde stage I, which was characterized by moderate temperatures (260–320 °C) and fluid with a moderate salinity (5.0–6.0% NaCl equiv.). Low temperature (180–200 °C) and low salinity (2.0–3.0% NaCl equiv.) were responsible for retrograde stage II. Au mineralization is mainly associated with chalcopyrite and tennantite in retrograde stage I and with tellurobismuthite in retrograde stage II.

缅甸南部Shan邦Kalaw乡瑞敏邦地区的地质和Skarn Cu–Bi–Au矿化

Shwe Min Bon Cu–Au矽卡岩矿床位于缅甸最大的Au–Cu带之一内。该矿床位于Shan山陡坡带上，该区域标志着缅甸西部盆地与东部the邦高原之间的边界。Shwe Min Bon矿床包括矽卡岩型变质作用蚀变，并且Cu-Au矿化发生在Nwabangyi白云岩与Shweminbon组与白垩纪闪长岩之间的接触面上。交代过程导致了外骨骼的前向和逆向矿物组合。瑞敏邦矿床的热液活动分为逆行，逆行阶段I和逆行阶段II。渐进矽卡岩分为近端石榴石矽卡岩和次要斜辉石，而远端硅灰石矽卡岩。亚氯酸盐，附子，在逆行阶段I形成了透闪石-阳起石。Cu-Au矿化主要发生在逆行阶段I，其特征是温度适中（260-320°C）和盐度适中（5.0-6.0％NaCl当量）。 ）。低温（180–200°C）和低盐度（2.0–3.0％NaCl当量）是第二阶段的逆过程。金矿化主要与逆行阶段的黄铜矿和钙钛矿有关，而与逆行阶段的碲锌锰矿有关。
