L174 Broken Hill 2D Seismic Survey , NSW, 2005 Stacked and Migrated seismic data and images for lines 05GA-BH1 and 05GA-BH1EXP

The 2005 Broken Hill High Resolution 2D Seismic Survey, contracted to Terrex Seismic Pty Ltd for ANSIR (Australian National Seismic Imaging Resource) and New South Wales Department of Primary Industries - Mineral Resources. The survey operation was located approximately 6km north east of the town of Broken Hill in western New South Wales. The high resolution 120 fold seismic reflection survey was carried out in August 2005 along a 12 km portion of the seismic line 96AGS-BH1B in the Broken Hill region that was recorded by the Australian Geological Survey Organisation (AGSO) in 1996-97. The purpose of the new survey was to compare high resolution seismic data with low fold explosive seismic data along the same line and to image geological structures at shallow crustal levels. Two HEMI-60 Vibroseis trucks were used as sources. A total of 12.2 km of 120 fold seismic reflection data were acquired to 16 s TWT, except for the last 2 km of the profile where the fold was decreased to 60.Raw data for this survey are available on request from [e-mail]

2005年布罗肯希尔高分辨率二维地震勘探项目由特雷克斯地震私人有限公司（Terrex Seismic Pty Ltd）承揽，服务于ANSIR（澳大利亚国家地震成像资源库，Australian National Seismic Imaging Resource）与新南威尔士州primary产业部矿产资源部门。本次勘探作业区域位于新南威尔士州西部布罗肯希尔镇东北约6公里处。该高分辨率120次覆盖地震反射勘探于2005年8月实施，沿布罗肯希尔地区1996-1997年由澳大利亚地质调查组织（Australian Geological Survey Organisation，AGSO）采集的96AGS-BH1B地震测线的12公里段开展。本次新增勘探的核心目标为：沿同一测线对比高分辨率地震数据与低覆盖度炸药震源地震数据，并对浅部地壳尺度的地质构造进行成像。本次勘探采用两台HEMI-60型Vibroseis可控震源卡车作为震源，共采集12.2公里的120次覆盖地震反射数据，采集记录时长可达16秒双向旅行时（Two-Way Travel Time，TWT）；仅测线剖面最后2公里段的覆盖次数降至60次。本项目的原始数据可通过邮箱[e-mail]向客户服务部门申请获取。
