人们普遍认为,金在大多数低温热液矿床中的极低含量几乎难以用物探方法来直接发现它。本文通过分析热液蚀变造成的岩石物理性质变化表明,物探方法有助于圈定蚀变带的深部范围,并借此阐明产生热液蚀变的地热系统的原水文学以及指出贵金属矿化的有望区。但是所有的低温热液系统不见得会有一组相同的物探异常,这些异常是由热液流通过岩石时形 It is generally accepted that the extremely low levels of gold in most low-temperature hydrothermal deposits are almost impossible to detect by geophysical methods. The analysis of changes in petrophysical properties caused by hydrothermal alteration shows that geophysical methods can help to delineate the deep extents of altered zones and to clarify the hydrology of geothermal systems that produce hydrothermal alteration and indicate the promise of precious metal mineralization Area. However, all cryogenic hydrothermal systems do not necessarily have the same set of geophysical anomalies that are caused by the hydrothermal flow through the rock
