Objective Among globally known industrial helium-enriched natural gas reservoirs, associated helium is dominantly crust-derived helium(4He), which is generated by the radioactive decay of uranium(U) and thorium(Th) in crustal rocks. These rocks with old ages are also defined as helium source rocks.Published accumulation models for helium have revealed that granite is the main and effective helium source rock in the crust(Li YH et al., 2018).展开更多
