East Cobar (P200029), 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 East Cobar (P200029) contains a total of 3505 point data values acquired at a spacing between 1000 and 4000 metres. The data is located in NSW and were acquired in 2000, under project No. 200029 for New South Wales Department of Mineral Resources (NSWDMR).

重力测量数据可用于表征地球地表下方岩石密度变化所引发的微小重力场变化。所采集的数据将采用标准化流程进行处理，以确保所记录的重力响应仅源于地下岩石。经处理后得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量质控，以确保GA发布的最终数据满足实际应用需求。本次东科巴数据集（East Cobar，项目编号P200029）共计包含3505个测点数据，测点布设间距介于1000米至4000米之间。该数据集的采集区域位于新南威尔士州（New South Wales，简称NSW），数据采集工作于2000年完成，隶属于新南威尔士州矿产资源部（New South Wales Department of Mineral Resources，简称NSWDMR）的200029号项目。
