Unfortunately, hydrothermal zircons that grow directly from mineralizing fluids and inherited magmatic or metamorphic zircons from wall rocks may .

Detailed studies on zircons from the Jianfengling granite in the Baolun gold deposit indicate that the zircons can be divided into magmatic and hydrothermal zircons.

In this paper, we report U-Pb age and Hf isotope composition of hydrothermal zircons from a quartz vein within an UHP eclogite outcrop from the Hong’an area, western Dabie orogen.

14C dating and carbon isotopic tracing of hydrothermal petroleum in the Guaymas Basin show that the hydrothermal petroleum is generated in recent epochs.

The paper briefly introduces the forming temperature and migration of hydrothermal petroleum in order to prove there exists paragenetic relationship between hydrothermal petroleum and ore-forming fluids by some evidence examples.

The writers have studied the Pb isotopic composition of quartz in hydrothermal quartz veins in the Zoige uranium deposit, and regard Pb isotopic ratios of quartz as a bridge linking up the Pb isotopic of the composition parent rocks with that of ores to determine the source of U.
