Abstract:

The Arabian-Nubian Shield (ANS) is a complex Neoproterozoic tectonic mosaic whose lithospheric structure and geothermal regime remain poorly constrained. Here, for the first time across the entire ANS, we integrate S-wave tomography, seismic velocity models, lithospheric density from Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite data, and Land Surface Temperature (LST) derived from Moderate Resolution Imaging Spectroradiometer (MODIS) imagery to map crustal and upper mantle architecture. Results show stark lithospheric contrasts: the stable Arabian Platform has thick, cold lithosphere (Moho depth ~ 32.5 km, lithosphere-asthenosphere boundary (LAB) > 200 km) and low heat flow (40-50 mW/m²), whereas the Arabian Shield and Red Sea rift exhibit thin lithosphere (Moho 25-30 km, LAB 60-120 km) with high heat flow (70-90 mW/m²). These areas display low S-wave velocities (≤ 3920 m/s), reduced mantle density, and high-temperature anomalies indicative of active mantle upwelling and lithospheric thinning. This multi-parametric framework identifies zones of pronounced lithospheric thinning as prime targets for geothermal exploration across the ANS and provides new insight into its Cenozoic geodynamic evolution.

Isothermal Processes

Isothermal Processes

A thermodynamic process that occurs at constant temperature is called an isothermal process. Heat slowly flows into the system or out of the system to maintain thermal equilibrium. Processes involving phase changes like water evaporation into steam or freezing water into ice at a constant temperature are examples of Isothermal Processes.
An ideal gas can also undergo isothermal expansion or compression.
For example, consider 1 mole of an ideal gas inside an isolated cylinder at initial volume V...

Modeling and Similitude

Modeling and Similitude

Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...
