Preserving the impossible: conservation of soft-sediment hominin footprint sites and strategies for three-dimensional digital data capture. [PDF]

, 2013
Human footprints provide some of the most publically emotive and tangible evidence of our ancestors. To the scientific community they provide evidence of stature, presence, behaviour and in the case of early hominins potential evidence with respect to ...

Three-Dimensional Structural Geological Modeling Using Graph Neural Networks [PDF]

Mathematical Geosciences, 2021
AbstractThree-dimensional structural geomodels are increasingly being used for a wide variety of scientific and societal purposes. Most advanced methods for generating these models are implicit approaches, but they suffer limitations in the types of interpolation constraints permitted, which can lead to poor modeling in structurally complex settings.

Numerical simulation of geothermal field in a three-dimensional multi-fractured geological model of Zhuolu Basin

, 2021
The prediction of the geothermal field is an important prerequisite for the evaluation of geothermal resources. Much attention has been paid to the research on coupled temperature field of percolation-heat transfer in deep fractured rock mass. The Zhuolu
