产于陆相火山岩系中或者是相邻岩石中,而且是形成温度低于300℃,在这其中成矿流体必须是大气降水与岩浆热液所形成的混合热液,这一类型的金矿床被称之为浅层低温热液金矿。随着近些年来对浅成低温热液金矿的不懈研究,其大量的研究成果突破了浅成低温热液金矿只在新生代火山岩系中形成的概念理解,打破这一概念的是在石炭纪陆相火山岩中也同样发现了浅成低温热液金矿。通过大量实践证明和研究浅成低温热液金矿一般情况下,只在岛弧环境和大陆边缘环境中,还有酸性陆相火山岩系以及相邻岩石中形成产生。
Produced in continental volcanic rocks or adjacent rocks, and the formation temperature is below 300 ℃, in which the ore-forming fluid must be a mixture of hydrothermal hydrothermal precipitation and the formation of this type of gold deposit Is called a shallow low temperature hydrothermal gold. With the unremitting research on epithermal gold deposits in recent years, a large number of research results have broken through the concept understanding that epithermal gold deposits only formed in the Cenozoic volcanic rock series. Carboniferous continental volcanic rocks are also found in shallow epithermal gold deposits. Through extensive practice, it has been proved and studied that epithermal gold deposits are generally formed only in the arc environment and continental margins, acidic continental volcanic rocks and adjacent rocks.
