Dr. Behnam Sadeghi, from EarthByte Group (USYD), has published a new review paper in “Ore Geology Reviews”. Sadeghi et al. (2015) proposed simulated-fractal models for the first time, which is based on the combination of geostatistical simulation models and mathematical fractal/multifractal modeling to classify geochemical anomalies. Based on that research, several other models have been … Read more…
Dr. Behnam Sadeghi, in 2020, was introduced as the first recipient of the “Founders Scholarship” award of the International Association for Mathematical Geosciences (IAMG), now being presented annually to the most outstanding student or post-graduate scientist in the field of Mathematical Geosciences. This award is given in honor and memory of the individuals who participated … Read more…
GPlates is a free desktop software for the interactive visualisation of plate-tectonics. The compilation and documentation of GPlates 2.3 data was primarily funded by AuScope National Collaborative Research Infrastructure (NCRIS).

Behnam Sadeghi has published this paper in the Iranian Journal of Earth Sciences. In this research, he has developed an algorithm to down-scale the maps, to reduce the simulation time and the required memory, but to keep the same geostatistical performance and accuracy. This model strongly helps with huge and time-consuming simulations. Abstract In geochemical … Read more…
Weighting of BLEG data with drainage and catchment properties to enhance Au anomalies Dr. Behnam Sadeghi with Profs.

A paleo-digital elevation model (paleoDEM) is a digital representation of paleotopography and paleobathymetry that has been “reconstructed” back in time. This report describes how the 117 PALEOMAP paleoDEMS (see Supplementary Materials) were made and how they can be used to produce detailed paleogeographic maps. The paleoDEMS describe the changing distribution of deep oceans, shallow seas, … Read more…
