Geothermal Resource Assessment on Sumatra Island: Estimating Thermal Gradient and Heat Flow Based on Aeromagnetic Data via Curie Point Analysis

Journal of Applied Science and Engineering
Geothermal exploration on Sumatra Island is gaining momentum as Indonesia undergoes the shift to the use of sustainable energy resources. Exploration is nevertheless hindered by the limited deep boreholes and the tectonic and geological complexity of ...

Basic characteristics and metallogenic potential of banded iron formation(BIF) in the southern Prince Charles Mountains, East Antarctica

Dizhi lixue xuebao, 2021
Banded iron formation(BIF) occurs in the lower part of the Paleoproterozoic Ruker Group at Mount Ruker, southern Prince Charles Mountains in East Antarctica. Of all depositional sequence of the Ruker Group, at least 400 m is of iron-bearing formation and

Aeromagnetic data workshop

Eos, Transactions American Geophysical Union, 1983
A workshop on aeromagnetic data, sponsored by the National Geophysical Data Center (NGDC) of the National Oceanic and Atmospheric Administration, was held in Boulder, Colo., November 16–18, 1982, to evaluate the requirements for a national aeromagnetic database. The following recommendations were developed by J . R.

Magnetic Dual‐Layer Equivalent Sources on the Sphere

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The equivalent source method is widely used for processing and interpolating magnetic data, particularly in airborne surveys. However, implementations based on Cartesian coordinates present limitations at regional and global scales, where Earth curvature introduces geometric inconsistencies that affect data integration and modeling accuracy ...

A high-resolution aeromagnetic survey over the Cape Roberts Rift Basin: Correlations with seismic reflection and magnetic susceptibility log data

, 2007
A high-resolution aeromagnetic survey (altitude 125 m asl, spacing 500 m , area 800 km2) was carried out in 1994 offshore of Cape Roberts by the GITARA (German ITalian Aeromagnetic Research in Antarctica) Group.

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Why Does the Broken Hill Deposit Sit in Resistive Crust? Magnetotelluric Evidence for Metamorphic Decoupling of a World‐Class Mineral System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The spatial association between electrical conductors and ore deposits underpins the widespread use of magnetotellurics (MT) in mineral exploration, yet not all mineral systems preserve a diagnostic conductive signature. Here, we present a high‐resolution MT study of the region hosting the world‐class Broken Hill Pb‐Zn‐Ag deposit (NSW ...

Aeromagnetic Compensation Algorithm Based on Principal Component Analysis

, 2018
Aeromagnetic exploration is an important exploration method in geophysics. The data is typically measured by optically pumped magnetometer mounted on an aircraft. But any aircraft produces significant levels of magnetic interference.

The Parguera Fault System: Possible Quaternary Reactivation of Bedrock Faults in Southwest Puerto Rico

Tectonics, Volume 45, Issue 9, September 2026.
Abstract We present evidence of a previously unrecognized east‐west‐trending normal fault, named the Parguera Fault, in southwest Puerto Rico. The fault is located at the northwestern edge of seismicity from the southwest Puerto Rico seismic sequence that began in 2019, near the coastal town of La Parguera.
