Northeast Coalfields - Tas Mines Dept (ECCP) (P197451), 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 Northeast Coalfields - Tas Mines Dept (ECCP) (P197451) contains a total of 473 point data values acquired at a spacing of 550 metres. The data is located in TAS and were acquired in 1974, under project No. 197451 for Mineral Resources Tasmania (MRT).

重力数据用于观测地球表层下方岩石密度变化所引发的微小重力场变化。采集所得的数据将采用标准方法进行处理，以确保记录到的响应信号仅源自地下岩石。经处理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核查，以确保GA发布的最终数据符合使用要求。本数据集为东北煤田-塔斯马尼亚矿业部（Tas Mines Dept, ECCP）（编号P197451），共包含473个测点数据，测点间距为550米。该数据采集于塔斯马尼亚州（Tasmania，简称TAS），采集时间为1974年，对应塔斯马尼亚矿产资源局（Mineral Resources Tasmania, MRT）编号为197451的项目。
