It was a wise decision. On the geological time scale, human presence on the planet can represent, at most, an event, not an epoch. This type of discussion/decision should stick to strictly geological criteria without being influenced by socio-political issues and pressures. https://lnkd.in/d_paADxC

Regional petrophysics: Paterson Orogen 2022-23: https://ow.ly/Cnl750Qi9bY This dataset includes petrophysical analyses on 1180 samples from 18 diamond holes located across the Great Sandy Desert. The drillholes penetrate Phanerozoic sedimentary sequences (Canning Basin) and basement rocks of the Paleoproterozoic igneous and metamorphic units of the Paterson Orogen. Released as part of an EIS-funded petrophysics project to sample diamond drillcore from across Western Australia. Petrophysical datasets can assist with the planning and interpreting of geophysical data, including characterizing the physical property response of stratigraphic units, alteration and mineralization styles, and constraining geophysical models of the subsurface. #EISfunded #ExplorationIncentiveScheme #Petrophysics #Phanerozoic #Paleoproterozoic

The Geological Society of America section meetings can be similar to the best focused conferences. Please consider submitting to one we are sponsoring in March (2025) in Arkansas: Session T22. The Value of Core and Cuttings in Obtaining Information on Basement Rocks of the Midcontinent that will take place at the South-Central meeting in Conway, Arkansas on March 9-11, 2025.   Session Description: Well core offers a unique opportunity to obtain valuable information on basement rocks that are normally restricted to the deep subsurface. Analysis of basement rock can enhance our understanding of the tectonic, and geochemical history of the Midcontinent. Core repositories archive this information and allow researchers to study basement rock. Abstract submission close on December 17, 2024 https://lnkd.in/gwGQ6ser

Join EEGS for the May TAG webinar “Passive Seismic Approaches for Active Geophysicists”  Tuesday, May 28, 2024  Register at: https://lnkd.in/ez5JvE4D Resonance frequencies are intrinsic properties of elastic media: they depend on their stiffness and mass distribution, and on their constraints.  In geological and geophysical applications, resonance frequencies are traditionally assessed by means of the microtremor H/V seismic method.  Resonance frequencies can quite easily be converted into the corresponding depths of seismic reflectors responsible for the occurrence of those resonances, in the presence of a Vs estimate. Since 1999, this has led to several interesting images of the main reflectors in the soil achieved by means of passive single station approaches.  However, resonances, being intrinsic properties, are expected to change only in amplitude and not in frequency with the measurement point, in a same medium. "How can we reconcile the fact that, as an example, a basin cross-section is a geological medium with characteristic and unique modal frequencies that do not change along the cross-section, with the fact that the H/V peak frequencies shift from the sides to the center of the basin? To answer this question, we’ll explore what we call 1D and 2D resonance and H/V or H&V approaches and provide some hints on how to discriminate and exploit the two cases. 

This week, as we celebrate Geophysics Day from Argentina, we extend our congratulations to all professionals in this exciting and valuable field of science. We also take this opportunity to invite you to join us for the April session of our 2024 webinar series titled "Shaping Your Seismic": Exploring Exclusion Zones in PaleoScan with Jake Marson. 🔗 Register >> https://lnkd.in/exTQ6WnP #subsurface #geoscience #geophysics
