Geological Survey of Tanzania (GST) and Ministry of Energy and Minerals of Tanzania have organized the Workshop “Launching High Resolution Airborne Geophysical Data at Julius Nyerera Convention Center (17 January, 2014, Dar es Salaam, Tanzania). Around 150 delegates have attended the workshop from government and private sectors.
Permanent Secretary (PS) of Ministry of Energy and Minerals Mr.Eliakim Maswi said – the surveys were carried out under the Sustainable Management of Mineral Resources Project, saying the purpose of the survey was to identify potential zones of mineralization. “The main objective of the project is to improve the socioeconomic impacts of mining for Tanzania and Tanzanians and therefore enhance local and foreign investments”, said PS.
GST Chief Executive Officer , Prof. Abdulkarim Mruma said: “geophysical data acquired through the high resolution airborne geophysical surveys allow fast and accurate delineation of mineralised targets and when augmented with geological and geochemical datasets are highly effective in attracting new exploration ventures.” Prof. Mruma noted that the availability of the modern geo-scientific data will stimulate investments into mineral and other sectors and will improve the effectiveness of exploration programs.

“Despite a steep appreciation in exploration spending over the past decade, the number of greenfield discoveries is falling every year. Narrowing this gap will require harnessing the power of big data and cloud computing, according to a presentation by Rio Tinto’s exploration chief Stephen McIntosh at the International Geophysical Conference in Melbourne.
“In a lot of cases, we have the data but we haven’t got the most out of it because of time constraints and our ability to find or “discover” this data,” Amanda Butt, McIntosh’s colleague and former manager of exploration and geophysics, said in a follow-up interview with Earth Explorer. “Now that we can do things more quickly, and efficiently we can get more effective information out of the data.”
Geophysics, in particular, has become an increasingly important exploration tool as the depth of the average discovery moves from close to surface in the 1950s to hundreds of metres deep. Indeed, geophysics contributed significantly to nine of the 16 greenfields discoveries Rio Tinto has made since 1996, including the Diavik diamond mine in Canada and more recently at the La Granja copper project in Peru.”

Delineation of regional and local fault networks, which gravity and magnetic data enable, is crucial in both conventional and unconventional exploration and production. In frontier regions, these data help to delineate the raised and subsided crustal blocks and depocenters, as well as the distribution of igneous rocks.
The course reviews all stages of gravity and magnetic survey design, as well as data acquisition and geological interpretation. These steps are put in the context of designing and executing overall exploration programs for both conventional and unconventional targets.
A complete set of course materials and lunch is included in this course.

“New depths of insight from the 3D earth imagery delivered by 3D DC data acquisition systems: field case examples from Nevada, New Zealand and British Columbia”
Date: Tuesday 14 May, 2013 @ 4:00PM
Venue: ESC 2093, Department of Earth Sciences, 22 Russell Street (2nd floor), University of Toronto
Abstract: The acquisition of a uniformly-distributed, all-directional, dense and deep-sensing (“true 3D”) DC geo-electric data set can provide the field observations needed to guide and constrain a 3D data inversion to a model earth result that is as objective and as subtly resolved as is practically possible. Whether the field acquisition technology is distributed or tethered, it is the data set itself that counts, and all 3D systems today (E-SCAN, ORION, NEWDAS) deliver the optimized true 3D field data sets as characterized above.
Having providing the hard-data basis for an enhanced level of trust in subtle image patterns, the new 3D imagery can help to understand both the anomalous targeted features and the often-subtler alteration envelopes or settings that may accompany them. These previously-unseen alteration patterns may themselves represent new resource targets. They can also provide guidance as to the probable location of otherwise non-responsive targets of interest, resource zones that are perhaps too small in volume or too weak in response to be directly identifiable with any geophysical technology.
We show how 3D alteration pattern imaging indirectly locates the otherwise geophysically-invisible Gwenivere ore veins at Great Basin Gold’s Hollister mine, and how that signature leads to nearby targeting. Another Hishikari-like setting in New Zealand and an answer to narrow-vein mapping problems in the Toodoggone (BC) district illustrate the new opportunities to understand not just ore signatures, but the imprinted patterns of entire hydrothermal signatures on host lithology.
This is a 2-day workshop consisting of 1 day of lectures (April 24th) followed by a 1 day hands-on workshop (either April 25th or 26th). Delegates can register for just the lectures or both the lectures and workshop.

Land seismic is currently undergoing what, in a generally slowly evolving field, amounts to a revolution. This revolution involves the use of a variety of new technologies but is principally concerned with reduction. The introduction of high channel-count recording systems has enabled reliable point-receiver acquisition. Coupled with advanced data processing techniques this enables a reduction in the number of sensors required on the crew. This in turn results in reduction in the number of crew members and thus survey cost, including the environmental cost. Acquisition cost can also be reduced through the use of advanced source acquisition methodologies that reduce the source cycle time (the time taken between the acquisition of records). An increase in the size of vibrators has also allowed a reduction in the number of vibrators on the crew and their related logistic burden.
An area of particular interest currently is the recording of data with enhanced the low-frequency content of the data. Increased low-frequency content has a variety of benefits, it helps overcome the high-frequency attenuating effects of the earth, improves vertical resolution, enhances inversion results, and improves: velocity analysis, minimum phase deconvolution and wavelet estimation. Acquiring such data involves lowering both the minimum frequency transmitted by the source as well as the ability of the sensors to record such frequencies.

MATT HALL: “This year is the 20th anniversary of the release of Seismic Un*x as free software. It is six years since the first open software workshop at EAGE. And it is one year since the PTTC open source geoscience workshop in Houston, where I first met Karl Schleicher, Joe Dellinger, and a host of other open source advocates and developers. The EAGE workshop on Friday looked back on all of this, surveyed the current landscape, and looked forward to an ever-increasing rate of invention and implementation of free and open geophysics software.
Rather than attempting any deep commentary, here’s a rundown of the entire day:..”
