Geology Toolkit Lite

Contains Ads

Geology Toolkit is a complete android application which allows geologists to examine and explore minerals and rocks features under microscope or hand-specimen properties.

Geology Toolkit makes mineralogy and petrology to be easier to examine a thin section and to understand the characteristic properties of each mineral/rock without a petrographic microscope, which is known to be very expensive. It is mainly addressed to geoscience students/geologists as a guide in individual or supervised laboratory work.

Made by a Geologist for Geologists.


β–Ί Premium design and Ad free
The interface is user-friendly, ad-free and very intuitive, the main menu can be accessed every time by swiping your finger horizontally across the screen or by pressing the 'hamburger' icon in the top left corner.

β–Ί GeoQuizzes - Learn by doing!
Test your geology knowledge of the material on this application or from the class / laboratory/field with these GeoQuizzes.
