An experimental investigation on the damage mechanisms of red glutenite in the Mount Wuyi cultural and natural heritage site subject to acid rain and wet-dry cycles: a macro-to-micro approach

Heritage Science
The safety of rock landscapes in Mount Wuyi is significantly impacted by acid rain and wet-dry cycles. In this paper, the decay characteristics of the physical–mechanical properties of red glutenite were investigated under acidic wet-dry cycles.

Prediction of glutenite reservoirs using an adaptive Bayesian seismic inversion in the slope zone of Mahu Depression in Junggar Basin, NW China

Unconventional Resources, 2022
The slope zone of Mahu Depression in Junggar Basin contains the largest glutenite oilfield discovered over the world so far. However, because of the mechanism of near-source sedimentation and rapid facies transition, the glutenite reservoirs are strongly
