Low saline aqueous carbonic fluids are considered to be the ore forming solutions for orogenic lode gold deposits. Phase separation/fluid immiscibility of the ore fluid is quite common and is one of the major reasons for deposition of gold in these deposits. Abundant carbonic fluid inclusions have been observed in quartz grains of Hira-Buddnini Gold Deposit. Theoretical estimation indicates that more volume of H₂O compared to CO₂ is likely to be trapped in inclusions at different P-T conditions. Preferential loss of H₂O from fluid inclusions during ductile deformation of quartz grains have been attributed as the suitable reason for abundance of carbonic fluid inclusions.

印度Hutti-Maski绿岩带Hira-Buddini金矿床中碳流体包裹体的丰富度：岩相学和流体成分体积比估算的推论

低盐含量的含水碳酸流体被认为是造山矿金矿床的成矿溶液。矿石流体的相分离/流体不溶混性很普遍，并且是在这些矿床中沉积金的主要原因之一。在Hira-Buddnini金矿床的石英晶粒中观察到大量的碳流体包裹体。理论估计表明，在不同的PT条件下，与CO ₂相比，更多的H ₂ O可能被夹杂在夹杂物中。石英颗粒的延性变形过程中，流体包裹体中H ₂ O的优先损失已被认为是碳流体包裹体丰度的适当原因。
