Subject: [SEGMIN]: Another Airborne Gravity Gradiometer Development: The
Crowded Skies?
> More activity on the airborne gravity front by our antipodean colleagues.
> -----------------------------------------
> CSIRO in Australia made the following announcement last week - see

>
> The gravity gradiometer project at CSIRO is quite separate from the
> "Falcon" system which BHP is now flying on two continents, and would
> appear to be three years from general commercial application.

> The discovery of giant new mineral deposits, invisible to present
> exploration methods, is a step closer with the formation of an
> international research consortium to develop a revolutionary precision
> airborne instrument.
>
> CSIRO Exploration and Mining, AngloGold Australasia, Anglo American and
> De Beers announced today that they have signed a
> collaborative agreement to develop an airborne gravity gradiometer
> suitable for detection of buried orebodies and geological
> structures.
>
> The new contract is for AU$7.4M with AU$6.4M being provided by the
> industry partners and AU$1M from CSIRO. The project is
> scheduled for completion in 2003.
>
> "Anglo American, De Beers and AngloGold have a long and successful
> track record of high powered Research and Development and
> a continued commitment to leading edge technologies to ensure their
> competitive advantage in minerals prospecting" said Eddie
> Kostlin, Vice-President: Geophysics at Anglo American.
>
> "We have looked at all available options for airborne gradiometry and
> are looking forward to collaborating with CSIRO on this
> project which has such broad application for exploration in Australia
> and elsewhere.
>
> The investment is seen as part of our recent commitments to the
> exploration and mining industry in Australia," said Mr Kostlin.
>
> Over the past four years, a proof of concept system has been developed
> by a team of ten CSIRO scientists and engineers led by Dr.
> Mike Gladwin, Dr. Rhodes Hart and Dr. Craig P. Smith at the Queensland
> Centre of Advanced Technologies. The initial research was
> fully internally funded by CSIRO.
>
> "For the gradiometer application, we have extended technology we
> previously developed for precise measurements of the earth that
> are associated with earthquake deformation processes," said Dr.
> Gladwin.
>
> "With the gradiometer, we measure movements as small as one thousand
> millionth of a millimetre. This new system avoids many of the
> problems of instruments developed elsewhere."
>
> "Ultimately, the system will provide the industry with enhanced mapping
> of the geological structures.
>
> "This is part of CSIRO's "Glass Earth" Initiative which aims to
> visualise the structure and mineralogy up to one kilometre deep into the
>
> Earth's surface," said Dr Bruce Hobbs, CSIRO's Deputy Chief Executive
> for Minerals and Energy.
>
> Airborne gravity has been an unexploitable tool in geological mapping.
> Till now, airborne exploration has been based on combinations
> of data from magnetics, electromagnetics, natural gamma spectrometry
> and infrared surface spectrometry.
>
> Gravity gradiometry completes the essential set of technologies needed
> to turn the top kilometre of the Earth's crust "transparent" for
> mineral exploration and geophysical purposes.
>
> "CSIRO has played an important role in development of all of these
> technologies, and expects to do the same in measurement and
> interpretation of airborne gravity gradiometry," said Dr. Hobbs.
