Lineaments interpreted from Gravity Data

This dataset comprises lineaments interpreted from 250m gridded gravity data. The data is presented as Bouguer gravity using an industry standard reduction (continental crust) density of 2.67 T/m3 for the density of bedrock . Analysis has focussed on interpreting structural trends not addressed closely by the work completed by the former Department of Primary Industries (DPI) - specifically NNE-SSW, ENE-WSW and WNW-ESE trends. \n\nThe dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.

本数据集包含从250米网格状重力数据中解译得到的线性构造（lineaments）。该数据以布格重力（Bouguer gravity）形式呈现，采用行业标准校正流程，以2.67吨/立方米的大陆地壳密度作为基岩密度。本次分析聚焦于解译原初级产业部（Department of Primary Industries, DPI）此前相关工作未细致涉及的构造走向，具体包括北北东-南南西（NNE-SSW）、东北东-西南西（ENE-WSW）以及西北西-东南东（WNW-ESE）走向。

本数据集由GHD编制，用于为DEPI的未来权益保障分配（Secure Allocation Future Entitlements, SAFE）项目的报告《地质构造对地下水流动系统的潜在影响》提供支撑。
