Radiometric Grid of Australia (Radmap) v4 2019 unfiltered pct potassium

The unfiltered potassium grid is a derivative of the 2019 radiometric grid of Australia. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data are collected on airborne geophysical surveys conducted by Commonwealth, State and Northern Territory Governments and the private sector. The 2019 unfiltered potassium grid has a cell size of about 100 m (0.001 degrees) and shows potassium element concentrations of the Australia region. Potassium is the seventh most abundant element in the Earth's crust. The potassium concentration grid can be used to locate minerals and compounds containing potassium.

未滤波钾元素网格是澳大利亚2019年放射测量网格的衍生数据集。放射测量法，亦称伽马射线能谱法，通过检测地球表面附近的伽马射线，来反映钾（K）、铀（U）以及钍（Th）的天然放射性衰变所引发的自然变化。该数据集由澳大利亚联邦、各州、北领地政府以及私营部门开展的航空地球物理调查采集所得。2019年版未滤波钾元素网格的单元格分辨率约为100米（0.001度），展示了澳大利亚全域的钾元素浓度分布情况。钾是地球地壳中丰度排名第七的元素。该钾浓度网格可用于定位含钾矿物及含钾化合物。
