Data analysis of the U-Pb geochronology and Lu-Hf system in zircon and whole-rock Sr, Sm-Nd and Pb isotopic systems for the granitoids of Thailand.

This data article provides zircon U-Pb and Lu-Hf isotopic information along with whole-rock Sm-Nd, Sr and Pb isotopic geochemistry from granitoids in Thailand. The U-Pb ages are described and the classification of crystallisation and inherited ages are explained. The petrography of the granitoid samples is detailed.

Genesis and preservation of a uranium-rich paleozoic epithermal system with a surface expression (Northern Flinders Ranges, South Australia): radiogenic heat driving regional hydrothermal circulation over geological timescales.

The surface expressions of hydrothermal systems are prime targets for astrobiological exploration, and fossil systems on Earth provide an analogue to guide this endeavor. The Paleozoic Mt. Gee-Mt.
