EFFECT OF PEBBLE SIZE ON GOLD DISTRIBUTION IN THE BANKET SERIES OF THE STRATIGRAPHY IN TARKWAIAN SUPERGROUP [PDF]
Geological Behavior, 2022 The purpose of this research is to establish the relationship between the gold grades and the various pebble sizes from a mine. This objective was reached by choosing parameters of interest from the logging and sampling data, lithological data and assay ...

PETROGRAPHY AND THERMODYNAMIC REACTIONS OF SOME OF THE ROCKS IN THE BANKET SERIES OF THE TARKWAIAN SUPERGROUP [PDF]
Geological Behavior, 2023 The Banket Series, which is a paleoplacer deposit, is the third formation in the stratigraphy of Tarkwaian Supergroup. This project seeks to study petrographically; the lithologies in the banket series to confirm the rocks identity as already known or ...

Dielectric properties and stratigraphy of regolith in the lunar South Pole-Aitken basin: Observations from the Lunar Penetrating Radar [PDF]
A&A 661, A47 (2022), 2022 We examine data obtained by the Lunar Penetrating Radar (LPR) onboard the Chang'E-4 (CE-4) mission to study the dielectric properties and stratigraphy of lunar regolith on the far side of the Moon. The data collected from January 2019 to September 2020 were processed to generate a 540 m radargram.

Stochastic resetting by a random amplitude [PDF]
Phys. Rev. E 103, 052123 (2021), 2021 Stochastic resetting, a diffusive process whose amplitude is "reset" to the origin at random times, is a vividly studied strategy to optimize encounter dynamics, e.g., in chemical reactions. We here generalize the resetting step by introducing a random resetting amplitude, such that the diffusing particle may be only partially reset towards the ...

Sensitivity of isochrones to surface mass balance and dynamics
Journal of Glaciology, 2023 The interior of an ice sheet consists of layers of accumulated snow, which contain important information on accumulation and ice dynamics that are imprinted on layer shapes over time.
