Mt Webb Wilson Webb percent potassium grid geodeticg

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 collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.This radiometric potassium grid has a cell size of 0.00083 degrees (approximately 89m) and shows potassium element concentration of the Mt Webb-Wilson-Webb merge, 1995-1998 in units of percent (or %). The data used to produce this grid was acquired in 1995 by the WA Government, and consisted of 89949 line-kilometres of data at 400m line spacing and 80m terrain clearance.

辐射测量法（又称伽马射线能谱法）通过探测地球表面附近的伽马射线自然变化，量化钾（K）、铀（U）与钍（Th）的天然放射性衰变产生的辐射信号。所采集的数据将通过标准流程开展处理，以确保记录的响应仅源自地下岩石的辐射信号。最终生成的数据集可通过解译分析，揭示地下地质构造特征。经澳大利亚地质调查局（Geoscience Australia，以下简称GA）地球物理学家开展质量核验，确保GA发布的最终数据符合使用要求。
本次发布的辐射测量钾元素网格数据，网格单元尺寸为0.00083度（约合89米），展示了1995-1998年Mt Webb-Wilson-Webb合并区域的钾元素浓度分布情况，单位为百分比（%）。用于生成该网格的数据由西澳大利亚州政府于1995年采集，原始数据总线长89949线公里，测线间距为400米，地形离地高度为80米。
