OTHER SERVICES

Due to the nature of our work, and a variety of tools we use in the development of each of our projects, we offer specific services in thematic cartography; description of geological samples and training, as well as the rental of our petrographic microscope and sale of Geological compasses.

Remote sensing analysis

By carrying out a muti temporal interpretation of aerial photographs, satellite images, and DEM it is done a characterization, and mapping of geological attributes (units, structural layout, guidelines, etc.), geomorphological units and processes, and hydrogeological features such as springs, wetlands, recharge areas, etc.

Elaboration of maps and cross sections

Through the use of software such as QGis, ArcGis, or AutoCad, spatial information (identified in field trips and in the analysis of remote sensors) is digitized to generate maps where each element is characterized by its respective attributes.

Microscopic description

of geological samples

Thin sections are classified according to their compositional and textural characterization. The analysis is done by point counting. It also includes aspects of microdeformation to support tectonic analysis.

Macroscopic description

of geological samples

The hand samples are classified according to their textural and compositional characterization. It includes the description of parameters such as porosity, permeability, plasticity, consistency, among others (when applicable). It is done by using magnifying glass 10X, 20X, 50X and binocular loupe.

Macroscopic description

of cores

Core analysis includes a sedimentological, stratigraphic, structural and geotechnical characterization.

It is identified sedimentological properties such as granulometry, mineral composition, fossils composition, pore count, etc.

Stratigraphic attributes such as lamination, layers, bioturbation, imbrication and diagenetic characteristics such as dissolution, dolomitization, cementation and nodule development, etc.

Structural features like solution seams, recognizable stylolites, etc.

Geotechnical characterization is done as percentage of recovery and RQD.

TRAINING

Water quality monitoring

It is taught how to use multi-parameters and reagents to measure water quality conditions (pH, Eh, dissolved oxygen and temperature).

This information can be used by the communities to obtain an environmental base line or environmental initial reference values. Through monitoring, those values can be used as early contamination alerts and the objective selection of water sampling points for deeper chemical analysis. 

Remote sensing analysis

It is taught how to carry out the multi-temporal interpretation of aerial photographs and DEM as a tool for tectonic deformation and morphodynamic (landslides and erosion) characterization.
