Different Types of Geological Maps can be used quickly to view the Geology of any area, as well as where gold and other minerals have been found before.
Geological Maps are maps that just show the surface outcrops in the map area or interpretive maps that show the subsurface geology beneath the thin surface layers.
Finally the maps can be interactive so you can add extra layers to show just about anything you need to know about the Geology of a location.
Here is some examples of the many different types of Geological Maps of Western Australia that are available and they are usually downloadable free from the Department of Mines in WA (DMIRS).
How you do this is shown on the Download Free Geological Maps page or in other pages such as the Using Tengraph Web page that explains the use of Tengraph Web.
These factual simple Geological Maps of WA are downloadable free as a PDF or can be bought as a Paper copy. See this page Free Geological Maps of Western Australia.
This is and Interpretive Geological Map created using Geoviewer 1:500000 Geology Polygons over a Satellite view around Cue/Big Bell WA. Interpretive Geological Maps show the Interpreted Bedrock geology under the outcropping layers shown in a factual Geological Map.
There are many products and mapping software provided by the Department of Mines (DMIRS) in WA that enables you to use a number of sources to obtain information that you can layer over maps or configure maps to understand:
For example this next map which shows
Maps can be downloaded as tiled maps for complete mining areas such as Meekatharra Zone 50 1:100000 or 1:250000 maps and then data added and configured to show what you want to see.
This can be done on GeoMap.
This is a view of what a series of tiled Maps look like for the Meekatharra Mining District (shown in GeoMap).
In this view the tiled Geology map is overlaying a topographical map and then the 1:250000 and 1:100000 map boundaries are outlined over the top of them.
The difference between these maps that are joined together to get a seamless large maps used in the GeoMap software and the Factual Individual Geological map charts is the tiled maps do not include an Index or symbols legend.
A 1:250000 map tile in GeoMap - Cue SG50-15 (Geology layer is 50% Overlaying Topographic Map information)
The same 1:250000 map tile in GeoMap - Cue SG50-15 with layers for Goldmine occurrences (gold stars) and a interpretive Geoviewer 1:500000 layer showing the subsurface geological rocks and structures.
With GeoMap you can create interactive maps with different types of Geological Maps and all the Geological Information you require in the field.
If you use GeoMap while you travel in the bush you can see exactly what geology you are passing over and where the gold has occurred or found in the past.
You can also see tenements so you know where you can go prospecting.
GeoMap is a DMIRS product that you use offline in the field.
How to user GeoMap is provided in our training at GeoMap Training WA website which has some free training as well - just sign up for the free training there.
In Tengraph Web you can add any layer that you want to view information.
This includes; Topographical Maps, Geological Maps, Geological Polygons, Mines, Cadastre, Land use, Pastoral Stations, Native Title, Tenements, WAMEX exploration Reports - the list is almost endless. You can also interrogate that information.
The key point is that you can see the Geology where Gold occurs to they are effectively gold maps (link to page).
