A ground gravity survey, conducted in two parts between 23 August - 5 September 2013 and between 16-24 May 2014, was undertaken on pastoral leased Crown Land within the Alcurra, Agnes Creek and Tieyon 1:100 000 mapsheet areas in South Australia. A total of 821 gravity station readings were collected, comprising 689 readings made at new stations plus 88 done as repeats and 44 included as network base station measurements. The survey data acquisition was performed in conjunction with the ongoing Geological Survey of South Australia (GSSA) Musgrave Province mapping programme. The survey readings and associated particulars have been assigned a unique identity code 2014A1 to allow their incorporation into the South Australian government geoscience database SA_Geodata. The new gravity stations were read at ~2 km station spacings along many irregularly distributed access tracks and fencelines, the aim being to infill the BMR's original, 1970s vintage, 7 km x 7 km regional gravity coverage. The survey work was conducted by two GSSA staff: Philip Heath and Mark Flintoft. A Scintrex CG5 Autograv instrument (serial no. 050800135) was used for the duration of the survey, and gravity station position information was obtained using the Sokkia GRX1 Real Time Kinematic system. This survey was undertaken with the aid of 4WD vehicles. A decision was made to use 4WDs for the duration of the survey, however, for future surveys elsewhere in the Musgrave region where road/track availability is reduced, it is recommended that all available types of GSSA field transportation resources be used for this type of survey, perhaps starting with 4WDs and then using quadbikes once some areas of interest have been defined. No accidents or incidents occurred during this survey. Two days’ work had to be repeated due to differential GPS instrument issues. These issues were resolved, and a Standard Operating Procedure (SOP) document has been constructed to ensure smooth field operation of the instruments in the future (see Appendix 1 for details). The GSSA's Musgrave Province mapping team plans to soon continue mapping to the west of the currently mapped area, after gaining final approval for entering into the APY Lands. The geophysics team intends to continue collecting gravity data as part of this ongoing field project.
