Here is a link to our paper we published this year in the online journal Geosphere. https://lnkd.in/gTmV9mCJ This paper discusses audio magnetotelluric (AMT) and magnetotelluric (MT) data collected across the highly mineralized, San Juan and Silverton caldera’s, San Juan County, Colorado. The data augments shallow resistivity measurements (~ 0 to ~350 m) from a 2019, helicopter-borne electromagnetic survey. Information on the resistivity of surficial deposits can be used to infer possible low resistivity ground water with high specific conductance pore water and having geoenvironmental implications. Deep resistivity derived from MT data images resistivity of caldera structures and mineralized areas within the calderas from (0 - 1km; AMT) and (0 - 10km, MT). The area was mined from 1872-1991 for Cu-Pb-Zn-Ag-Au. The image is of hydrothermal alteration along the Silverton caldera margin, South Silverton mining area.

An insightful study by Elizabeth Turner et al focused on validating “topographically driven fluid model for carbonate-hosted Zn deposits using direct and highly nuanced evidence derived from a suite of entirely in situ, mutually informing and constraining geochemical approaches” comes highly recommended for geologists interested in Cu-Zn paragenesis in late Devonian and Cenozoic units.

The geological compass – clinometer is used to measure: (1) the orientation of geological planes and lineations with respect to north; and (2) the angle of dip of geological features with respect to the horizontal. This allows an accurate record of the geometry of the features to be constructed. The compass – clinometer can also be used in conjunction with a topographic map to accurately determine location. https://lnkd.in/erFSnsyZ

Our recent application note delves into how NMR characterises the porosity, permeability, and pore size distribution of rocks, which in turn are some of the key properties used to establish possible reservoir and cap rocks for carbon storage. NMR can be used to see how carbon dioxide will react with the rock and other fluids within the reservoir system. GeoSpec, our TD-NMR solution for geological applications, has a method for determining capillary pressure, delivering faster and more reliable results than traditional measurement systems.

Did you know about sediment-hosted copper in Victoria? The research was carried out in collaboration between the Geological Survey of Victoria and #CSIRO Mineral Resources. #copper #criticalminerals #sedimentarybasins #sedimentology

Practical Geostatistics & Mineral Resource Estimation (Zambia Edition) with Dr Isobel Clark 9th - 13th September 2024 This course will be an interactive and participative workshop where participants will be encouraged to discuss their practice and compare it to others and recognised best practices. Real projects and case studies will form an important part of the workshop and participants will be encouraged to discuss and reflect on their organisations practices and ways to improve them.

Have you read the new report that examines the geochemical characterisation and interpretation of magmatic rocks from the poorly understood and underexplored Loch Lilly-Kars Belt in western New South Wales? Acquired as part of the Darling-Delamerian project, these geochemical data give new insights into the geodynamics of the Delamerian Orogen and its potential to host undiscovered minerals. The Loch Lilly-Kars Belt in particular, may have the potential to host copper-zinc-silver-gold deposits and critical minerals like cobalt. Results from this study will provide an improved evidence-base to guide decision-making for industry, government and academia.
