Unfiltered Potassium Element Concentrations Grid of Australia 2019

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年辐射测量网格（radiometric grid）的衍生数据集。辐射测量法（又称伽马射线能谱法）可测量地球表面附近探测到的伽马射线的自然变化，此类变化源于钾（K）、铀（U）与钍（Th）的自然放射性衰变。该数据由澳大利亚联邦、各州及北领地政府与私营部门开展的航空地球物理调查采集。2019年未滤波钾元素网格的单元尺寸约为100米（0.001度），展示了澳大利亚区域的钾元素浓度分布。钾是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与化合物。
