K2 from map to mountain
A bit of fun playing with real elevation data and combining textures. Animation made in Blender with Evee, but I needed a lot of World Machine help, a bit of Substance Painter and Designer and of course mapping software, in this case Surfer.
Feldspars are one of the most common minerals on Earth. There are two solid solution series of feldspar minerals: alkali feldspars and plagioclase feldspars. The end members of these solid solutions are potassium feldspar (orthoclase, microcline) (KAlSi3O8) – albite (NaAlSi3O8) – anorthite (CaAl2Si2O8). So, the alkali felspars range from orthoclase and microcline to albite. Accordingly, chemical formula of these minerals ranges from KAlSi3O8 to NaAlSi3O8 (because of K-Na substitution). And plagioclase feldspars range from albite to anorthite, so from NaAlSi3O8 to CaAl2Si2O8 (because of NaSi-CaAl substitution). Intermediate blended minerals are present for both sequences.

Garnet minerals are great group of silicate minerals with general chemical formula X3Y2Si3O12. X stands for divalent Ca, Mg, Fe and Mn cations and Y – for trivalent Al, Fe and Cr cations. There are two main groups of garnet minerals. One group is Uvarovite (Ca3Cr2Si3O12) – Grossular (Ca3Al2Si3O12) – Andradite (Ca3Fe2Si3O12) group. This group is called Ugrandite (based on the beginnings of garnet minerals names within this group). This group has calcium in X position and chromium, aluminum or iron in Y position. Uvarovite, Grossular and Andradite are end members of this group, but mixed compositions (example: Ca3(Al, Fe)Si3O12) are also common.
Another group: Pyrope (Mg3Al2Si3O12) – Almandine (Fe3Al2Si3O12) – Spessartine (Mn3Al2Si3O12). This group is called Pyralspite group. This group has aluminum in Y position and magnesium, iron or manganese in X position. All these three minerals can also blend with each other and form mixed minerals. Also, minerals of this group can blend to Grossular through calcium – magnesium, iron or manganese cations exchange. (Read more about illustration: https://strike-dip.com/garnets/)

This is why procedural environments should be loved! This desert is done on the base of the Green Mountain (posted below) node setup in World Machine. Offset area, some differences in roughness and colors, Blender Cycles lighting – and you get totally different look.
If you want PBR maps of this environment for your project you can get them there: https://gum.co/lLZic
Made with Geoglyph in World Machine and Blender. Base – elevation, erosion textures and coloring done in World Machine. I used Blender only for final image to get better lighting controls.
Color, elevation and normal PBR maps are shown at the lower picture. If you want these maps for your project you can get them there: https://gum.co/AVivj
QAPF, Gabbroic and Ultramafic Rock Classification Schemes
The idea with these pictures was to color them by using the colors (most common) of each corner mineral and blend these colors as the percentage of mineral changes. QAPF diagram represents only the normalized felsic (light colored minerals) part of the rock, so for this illustration I avoided adding mafic (dark colored) minerals. But after posting it on few social platforms, I realized that people naturally miss mafic minerals when they see granite, diorite or any other, especially gabbro. Similar situation with other schemes I posted there: https://strike-dip.com/rock_classification/. I have some ideas how to improve them. So, if you plan to copy these schemes and use them, either wait until I post improved versions or make sure you really understand why they are colored this way 😊
Formation Depth, Thickness and Cross Section Example
The task of this project was to show the thicknesses of two layers (the thickness maps not shown here). I called them Formation1 and Formation2 in this adapted public version. The data based on which it needed to be done was well logs (again, not all logs shown) and 3D seismic based depth map. The cross section with one of the depth maps is shown here. The same data, and more, is shown in 3D view. The top surface is cut so that the data below would be visible.
Water Pollution Plume
The task with this project was simple: create geological cross sections, interpolate polluted groundwater flux data and visualize it. I received the lithology and pollution concentration data of few wells. There were few pollutants each of which had to be interpolated and visualized.
For this picture I used the results of the study but made some adaptations and give no identification of the exact pollutant so that the data stays confident. The pollutant plume model is cut, and the outermost zero concentration surface and satellite map is cut as well so that the inner iso-concentration surfaces would be better visible.
Lithological-Micropaleontological Well Data
This was done long time ago as part of my final study thesis. I was working on detailed carbonate rock description in couple of wells. And beside that needed to define the stratigraphic boundary more precise. In these few wells this could be done by using conodonts (microfossils) so I had to sort hundreds of conodonts under the microscope. My poor eyes 😊
