... of the fastest erosionally exhuming mountain belts on Earth. Exhumation of the Bonar Range in Westland just to the northwest of the Alpine Fault is orders of magnitude slower. We report apatite and zircon fission-track ages from samples that were collected along an ENE–WSW profile across the central Bonar Range...

...Ismael Vera Rodriguez; David Bonar; Mauricio Sacchi ABSTRACT Noise contamination is an important problem in microseismic data processing, due to the low magnitude of the seismic events induced during fluid injection. In this study, a noncoherent noise attenuation technique based on a constrained...

... is much more susceptible to change as a result of metabolic activity, particularly because of the large surface area of the apatite crystals in contact with extracelluar fluid. For example, Pb and Cd (both toxic elements) can accumulate in bone ( Driessens and Verbeeck 1990 ), as well as a range of bone...

This is deduced from the age of the sedimentary sequence that postdates the major emplacement of the Guadalquivir units, which ranges from <9.5 Ma in the easternmost part of the basin ( García-García et al., 2014 ; Pérez-Valera et...

... ( a , b ) , b ) . Similar to BP, we also test the Ricker and Morlet wavelets for the SST. We set the number of voices per octave to a high value of 64. The octave number corresponds to the frequency range considered by the CWT, and the voice number is the scale number within each octave. The high...

These two effective filters were first applied to eliminate seismic random noise by Bonar and Sacchi (2012) and Amani et al. (2017) , respectively...

The Radon transform is an early random noise attenuation method that is used in denoising by truncating the energy in the Radon...

NLM is a random noise filter that uses the structure similarities (some kind of redundancy) between the small patches of the image itself. Bonar and Sacchi (2012...

Diminishing random noise arising during field-data acquisition is a long-term challenge in seismic data processing. In the past few decades, a wide range of methods have been introduced for seismic incoherent...

For example, sparse optimization methods are used to suppress random noise ( Wang and Geng., 2020 ); band-pass filtering is applied for high-frequency noise attenuation ( Yang et al., 2023 ); and median filtering is used to attenuate checkerboard, horizontal, and fading noise ( Bonar and Sacchi, 2012...
