Placer Gravity Laverton Sheet (P199135), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Placer Gravity Laverton Sheet (P199135) contains a total of 396 point data values acquired at a spacing of 1000 metres. The data is located in WA and were acquired in 1991, under project No. 199135 for None.

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力变动。所采集的数据均采用标准方法进行处理，以确保记录得到的重力响应仅由地下岩石引发。经处理得到的数据集可通过解译，用以揭示地下地质构造。经处理的数据由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用要求。本普莱瑟重力拉弗顿图幅（Placer Gravity Laverton Sheet，编号P199135）共包含396个测点数据，测点间距为1000米。该数据采集区域为西澳大利亚州（Western Australia，WA），采集工作于1991年完成，隶属于编号为199135的项目，委托方为无。
