One of the fastest ways for humans to store information in their long-term memory is to pair concepts with meaningful images. Visual learning has been found to have cognitive effects which stimulate imagination, therefore, enabling users to process the information faster. Neuroscientists from MIT (1) have found that the human brain can process entire images the eye sees for as little as 13 milliseconds (Figure 1).
This suggests the eyes allow the information to get into the brain rapidly enough to know where to look next, calibrating our eyes to move as quickly as it takes to understand what we’re seeing (1). This trait allows the ability to detect salience in cluttered scenes.
Take 2 minutes to view the video footage below and try to determine what the gold is associated with. When trying to communicate your scientific research to non-experts it is critical to be able to keep the listener engaged. This may mean cutting out scientific jargon, using illustrations, or creating a narrative with the data. This video simply rotates elements over an Fe and Si distribution maps. After viewing all the elements present, using a custom selection of overlayed distribution maps the user to draw off their knowledge to provide a more detailed interpretation. Depending on the viewer expertise this could be simply identifying that Al and K are associated with each other or that Si cross cuts the two. Further to this, that there are multiple deformation events occurring or just trying to determine where all the gold (Au) sits. The ability to be processing images as we look at them allows us to create a narrative with our knowledge, regardless on the viewers prior experience.

In the context of spatial data handling, the visualization process is the translation or conversion of spatial data from a database into graphics. Geologists utilizing the non-destructive, rapid analysis techniques of the Bruker M4 TORNADO micro XRF, provides the ability to create element distribution map overlays in minutes. Using these databases in real time, more maps can be created, many of them to convey a single idea or target a single mineral feature. These maps are changing from being final products presenting spatial information to interim products that facilitate visual thinking. The M4 TORNADO PLUS can convert sample datasets and translate them into to live knowledge bases to create or improve mapping tools that drive exploration.
Figure 3. Element distribution map overlay to distinguish distribution and interactions between Au with elemental distribution within a
phase or phase boundary.
Figure 3 highlights the structural evolution of the sample while also displaying the interaction gold (Au) and mercury (Hg) have with the system. It can be highlighted that the large gold clusters are associated/in proximity and orientated with quartz veining (pink) while there is also disseminated Au found within the Al-K bearing mineral phase. The M4 TORNADO PLUS offers the unique ability to pair concepts with meaningful images in real time, allowing us to create a narrative with our knowledge.
