Ultra-pure natural hydrogen discovery redefines China's energy potential

Chinese researchers report record natural hydrogen purity up to 98.24% in the Sichuan Basin, suggesting an inorganic deep-Earth source and rapid ascent along faults, challenging previous ideas that hydrogen is too leaky to be a reliable resource. The finding shows cratonic basins can host high-purity deposits, and if just 2% of underground natural hydrogen could be harvested, it would exceed energy from all proven natural gas reserves. The study outlines steps to map deep rocks, trace migration pathways, and use isotope tests to quantify ongoing production.

Massive Jurassic Sauropod Unearthed at Chinese Construction Site

Construction workers in Tongnan District, Sichuan Basin, China uncovered a partial, exceptionally well-preserved sauropod skeleton dating to about 147 million years ago (Late Jurassic). Scientists named Tongnanlong zhimingi, estimating the full animal at 23–28 meters (roughly 92 feet) long, with a large shoulder girdle and well-preserved vertebrae. The fossil’s preservation result from rapid burial in ancient mud and sandstone; the remains are housed at the Chongqing Museum of Natural History. The find sheds light on the size and distribution of giant Asian sauropods and suggests broader ancient connections across continents.

Milankovitch cycles reveal where ancient shale oil formed

Researchers link Milankovitch orbital cycles to the formation of shale oil in the Sichuan Basin, showing that wetter periods during high orbital eccentricity produced organic-rich lake muds that later became shale reservoirs. By combining crust/mantle data, rock cores, and Jurassic lake-mud gamma-ray records, they align sediment layers with orbital timing to better predict where high-quality shale oil formed. The study, published Sept. 30, 2025, notes shale oil’s extraction via fracking and related environmental concerns, but the method could improve exploration targeting.
