摘要

这项研究利用机载伽马射线光谱仪确定了巴西中部戈亚斯锡矿省（GTP）A 型花岗岩的辐射热产生情况。Pedra Branca块岩和Serra Dourada花岗岩富含锡和稀土元素，它们表现出异常的辐射热（5.5-15 µW/m³）。因此，它们被归类为高产热花岗岩（HHPG）。通过整合放射热数据、RGB 成像、磁力测量、密度模型和地质信息，我们将异常放射热与 GTP 发现的花岗岩中存在的矿化区域联系起来。我们使用地质信息、密度模型和全球其他花岗岩验证了我们的方法。事实证明，该方法可有效锁定高热值花岗岩。

Investigation of radiogenic heat production in granites of the Goiás Tin Province, Central Brazil

This study defines the radiogenic heat production of A-type granites in the Goiás Tin Province (GTP), Central Brazil, using airborne gamma-ray spectrometry. Pedra Branca Massif and Serra Dourada Granite are rich in tin, rare earth elements, and they exhibit anomalous radiogenic heat (5.5–15 µW/m³). They are therefore classified as high heat production granites (HHPG). By integrating radiogenic heat data, RGB imaging, magnetometry, density model and geological information, we associated anomalous radiogenic heat with mineralized regions present in the granites found in the GTP. Our methodology was validated using geological information, density model and other granites worldwide. It proved to be effective for targeting HHP granites.

期刊介绍： Geothermics is an international journal devoted to the research and development of geothermal energy. The International Board of Editors of Geothermics, which comprises specialists in the various aspects of geothermal resources, exploration and development, guarantees the balanced, comprehensive view of scientific and technological developments in this promising energy field. It promulgates the state of the art and science of geothermal energy, its exploration and exploitation through a regular exchange of information from all parts of the world. The journal publishes articles dealing with the theory, exploration techniques and all aspects of the utilization of geothermal resources. Geothermics serves as the scientific house, or exchange medium, through which the growing community of geothermal specialists can provide and receive information.
