Crustal thermal models that incorporate thermo-barometric data have been developed for estimating depth to 1300 ºC isotherm in two xenoliths provinces: Southeast Paraguay and Andean domain, in South American Platform. Uncertainties in model results has been minimized by imposing reasonable bounds on some of the key model parameters. Considering only the best fit results it is possible to infer average values for geothermal parameters at the surface. This imply heat flow of 86 mWm-2, radiogenic heat production of 1.8 µWm-3. Besides at Moho depth: heat flow of 21 mWm-2, radiogenic heat production of 4.5x10-3 µWm-3, temperature of from Southeast Paraguay. For the Andean Domain, we have the following values for the geothermal parameters: heat flow, 72 mWm-2, radiogenic heat production, 1.0 µWm-3 in surface and heat flow of 33 mWm-2, radiogenic heat production of 2.0x10-3 µWm-3 and temperature of 785ºC in Moho depth. The heat flux estimated for the southeastern Paraguay is higher than that for the Andean domain. This result is in agreement with differences in geological ages between these sites, since the age value for Paraguayan region is approximately 20% lower than the Andean one.

The area which transcends the Precambrian basement complex onto the Sokoto sector of the Iullemme-den basin in northwestern Nigeria presents a unique prospect for geothermal exploration research in the absence of regional heat production data, despite its tectonic history and depositional characteristics. In this study, geophysical exploration employing radiometric technique was adopted to classify the petrologic units within the fringes of the Iullemmeden basin and the adjoining crystalline basement complex so as to estimate the radiogenic heat potential within the terrain that may support geothermal considerations. Airborne radiometric measurements acquired over the area were digitized and processed to obtain radioelement concentration maps and the K/Th/U ternary map. Results show that the ranges of measured concentrations of 40K, 238U and 232Th are 4.6 to 18.9%, 0.7 to 4.9 ppm and 4.6 to 18.9 ppm respectively. Radiogenic heat estimation derived from radioelement data within eight petrologic units comprising quaternary sediments, schist, carbonates, shale/clay, younger granites, older granites, gneissic rock and migmatite showed that the lowest radiogenic heat production estimates ranging from 0.27–0.66 μW∙m−3 were recorded in the sedimentary terrain within the quaternary sediments while the highest radiogenic heat production values of between 2.04 to 2.34 μW∙m−3 were recorded in the basement com-plex within gneissic rocks. The spatial distribution of radiogenic heat in the area showed an increased heat gradient within the basement complex and a diminishing heat gradient over the Iullemmeded basin.

A recently released open file study of the depth-to-basement and basement heat flow is presented, which covers the Queensland portion of the South Nicholson Basin and includes basins underlying the Lawn Hill Platform and Georgina Basin. The present-day basement heat flow model is derived from an analysis of basement composition, structure and history, with the crustal radiogenic and mantle heat flow assessed separately. Resulting from an integrated, iterative interpretation and analysis of a wide range of publicly available spatially continuous geophysical and geological datasets, the heat flow model reproduces faithfully sharp and high-amplitude variations of the published heat flow at small distances. Variations are replicated through the integration of interpreted basement composition and a geologically driven determination of heat production within the radiogenic crustal layer. The values of mantle heat flow based on lithosphere thickness derived from seismic tomography models are consistent with published stable mantle heat flow under terranes of similar age. The long-wavelength regional variations can be attributed to the change in the thickness of the lithosphere. Regionally, the highest values of heat flow are found where radiogenic crust is the thickest and the composition is interpreted to comprise radiogenic intrusives.

The purpose of this study was to determine the analysis of radiogenic heat production, density and seismic velocity of the outcrops of the South Bangka Nyelanding geothermal rock. The X-ray Fluorescence (XRF) method is applied to obtain heat-carrying radioactive elements in the form of Uranium, Thorium and Potassium and other oxides which are useful for studying seismic density and velocity. The main oxides used in this study were SiO2, TiO2, Al2O3, MgO, CaO, K2O and P2O5. The results showed that the density increased from the composition of the mineral felsic (acid) - mafic (base). Conclusion, as for the relationship with heat production, the SiO2 and P2O5 elements experienced a significant decrease compared to other oxides. As for seismic velocity, the results show that seismic velocity has a strong correlation with density. Keywords: Radiogenic Heat Production, Seismic Velocity, Density, Oxides

This thesis presents research on high-temperature metamorphic processes. A recent development in petrological modelling of granulite facies rocks is reintegration of melt generated and lost during metamorphism. The aim of melt reintegration is to create bulk compositions suitable for modelling prograde subsolidus evolution. Melt reintegration methodology was applied to a low-pressure granulite assemblage containing unambiguous textural evidence for subsolidus andalusite. Melt reintegration methodology resulted in a bulk composition that stabilised subsolidus and modally correct andalusite, providing validation of this petrological modelling technique. Melting and melt loss modifies rock chemistry and a long-standing paradigm is that melting depletes rocks in heat producing elements (HPEs). However, comprehensive K–U–Th datasets taken from a number of terranes show that in metapelites, melting and melt loss does not deplete U–Th concentrations, with overall terrane averages suggesting bulk heat production partitioning between melt and residuum is essentially 1:1. Modelling of HPE concentrations derived from terrane-scale elemental mapping in central Australia show that low-pressure (150–175 °C/kbar) granulite-facies metamorphism was driven by elevated crustal heat production. This energy source resulted in extremely long-lived (> 150 Ma) low-P–high-T metamorphism. High thermal gradient metamorphism driven by this energy source is characterised by contractional structures, kinematically late temperature maxima, and tight clockwise P–T loops. Petrochronology (the nexus between the isotopic age of a mineral and its compositional controls) is being increasingly used to interrogate the thermobarometric record contained in metamorphic rocks. Combined zircon and monazite REE-isotopic U–Pb compositions from interlayered metapelite and metabasic granulites show essentially identical peak metamorphic assemblages were achieved by substantially different P–T–t paths. The metabasic rock composition reached peak conditions at least 30 Ma before the metapelite. While speculative, the thermal delay recorded by the metapelite may reflect thermal buffering associated with partial melting and persistent structurally focussed melt streaming.
