Corona Fowlers Gap 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 0.00021 degrees (approximately 21m) and shows potassium element concentration of the Fowler's Gap, Corona, NSW, Broken Hill Exploration Init., 1995 in units of percent (or %). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 47943 line-kilometres of data at a line spacing between 100m and 200m, and 60m terrain clearance.

辐射测量法（radiometric method），或称伽马射线光谱法（gamma-ray spectrometric method），用于测定地球表面附近探测到的伽马射线的自然变化，这些变化由钾（K）、铀（U）和钍（Th）的自然放射性衰变引起。采集的数据通过标准方法处理，以确保记录的响应仅源于地下岩石。处理结果生成的数据集可通过解译揭示地下地质结构。处理后的数据由GA地球物理学家进行质量检查，以确保GA发布的最终数据符合用途要求。
该辐射测量钾网格的单元大小为0.00021度（约21米），显示了1995年新南威尔士州（NSW）科罗纳（Corona）地区布罗肯希尔勘探计划（Broken Hill Exploration Init.）中福勒缺口（Fowler's Gap）区域的钾元素浓度，单位为百分比（%）。生成该网格所用的数据由新南威尔士州政府于1995年采集，包含47943测线公里的数据，测线间距为100米至200米，地形净空为60米。
