摘要
通过矿床地质特征、遥感图象解译、隐伏岩体预测、包体成分、成矿温度及稳定同位素等研究,认为老厂银铅锌矿床与金铜系列隐伏岩体有关,成矿时代为 50~86 Ma,成矿溶液以初始岩浆水为主,伴有雨水参与,成矿物质具多来源性,矿床属中温略偏高温的热液矿床。
On the basis of the study on deposit geology characteristics, remote sensingimage interpretation, prediction of hidden intrusive bodies, compositions ofinclusions, ore-forming temperature and stable isotope, it is considered thatthe Laoehaug Ag-Pb-Zn deposit is related to hidden intrusive bodies of theAu-Cu series, its ore-forming epoch is 50~86Ma, ore-forming hydrothermalsolutions consist largely of the original magmatic water coupled with themeteoric water, ore-forming substances are of multiple source and the oredeposit should be attributed to the mesothermal towards slightly deviatianto high-temperature hydrothermal one.
