Basalt is well known as an extrusive igneous rock erupts on land by volcanic eruption. It is darker, denser and finer grained compared to the familiar granite of the continents. The study reveals the thermoluminescence properties (TL) of basaltic rocks which collected in southeastern region of Turkey. With this study, the variations of glow curve of the basalt at the different grain sizes, different annealing temperature and different annealing time have been investigated. This study also includes, dose response and heating rate experiments. As a result, the basalt sample shows thermoluminescence properties with a wide peak about 200°C. The best TL sensitivity was observed at samples whose grain size is ~100µm. The basalt sample has a wide TL glow curve. A linearity for the values up to 155Gy and supralinearity between 155Gy and 615Gy in dose response are observed and it reaches to saturation beyond 615Gy. Thermal treatments at higher temperatures decrease the TL sensitivity.
玄武岩是一种众所周知的喷出型火成岩，通过火山喷发在陆地上形成。与大陆上常见的花岗岩相比，它颜色更深、密度更大且颗粒更细。该研究揭示了在土耳其东南部采集的玄武岩的热释光特性（TL）。通过这项研究，研究了玄武岩在不同粒度、不同退火温度和不同退火时间下发光曲线的变化。该研究还包括剂量响应和加热速率实验。结果表明，玄武岩样品在约200°C处呈现出一个宽峰的热释光特性。在粒度约为100μm的样品中观察到最佳的热释光灵敏度。玄武岩样品具有较宽的热释光发光曲线。在剂量响应方面，观察到高达155Gy的值呈线性，在155Gy至615Gy之间呈超线性，超过615Gy则达到饱和。较高温度下的热处理会降低热释光灵敏度。
