Glengarry Peak Hill Robinson Range Areas ABCD potassium grid geodetic

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 88m) and shows potassium element concentration of the Glengarry, Peak Hill, Robinson River(pt), GSWA,1994 in units of percent (or %). The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 118765 line-kilometres of data at 400m line spacing and 60m terrain clearance.

放射性测量法（radiometric method），又称伽马射线能谱法（gamma-ray spectrometric method），测量地球表面附近探测到的伽马射线自然变化，这些变化源于钾（K）、铀（U）和钍（Th）的自然放射性衰变。所采集的数据通过标准方法处理，确保记录的响应仅来源于地下岩石。处理结果生成的数据集可通过解释揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以保证GA发布的最终数据符合预期用途。
该放射性钾栅格的单元格大小为0.00083度（约88米），展示了1994年GSWA区域内Glengarry、Peak Hill、Robinson River（部分）的钾元素浓度，单位为百分比（%）。该栅格的数据由西澳大利亚州政府（WA Government）于1994年采集，包含118765线公里的数据，线间距400米，地形净空高度60米。
