Galilee Upper Permian coal measures gas contents from WCR

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement.\n\nThe processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nDry Ash Free Gas content and gas isotope data from drill core samples from various geological units were for the Galilee subregion. The geological units are the Upper Permian coal measures, Aramac Coal Measures of the Galilee Basin, and the Winton Formation which is a part of the Eromanga Basin. The gas content data was utilised to show the distribution of gas in the Upper Permian coal measures and to look at variation in gas contents with depth below surface. The gas isotope data provides an indication for the source of the gas.\n\n## **Dataset History** \n\nDry ash free gas contents and gas isotope data from coal seam samples were compiled by the Galilee BA team from well completion reports held in the QDNRM database.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) Galilee Upper Permian coal measures gas contents from WCR.

## **摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多份源数据集衍生而来，源数据集的相关信息已在本元数据声明的「谱系（Lineage）」字段中列明。

本衍生数据集的生成流程已在本元数据声明的「历史（History）」字段中予以说明。

针对加利利次区域（Galilee subregion），研究人员采集并整理了不同地质单元岩芯样品的干无灰基气体（Dry Ash Free Gas）含量与气体同位素数据。涉及的地质单元包括：上二叠统煤系（Upper Permian coal measures）、加利利盆地（Galilee Basin）内的阿拉马科煤系，以及隶属于埃罗曼加盆地（Eromanga Basin）的温顿组（Winton Formation）。气体含量数据用于表征上二叠统煤系内的气体分布特征，并分析气体含量随地表埋深的变化规律；气体同位素数据则可指示气体的成因来源。

## **数据集历史**
本数据集的煤层样品干无灰基气体含量与气体同位素数据，由加利利BA工作组从QDNRM数据库中收录的完井报告中整理汇编而来。
