We apply the Fission Track Analysis technique in apatites and zircons (AFTA / ZFTA) to obtain datings. The results derived from this technique allows the reduction of oil and gas exploratory risk, specifying:
In most analytical centers that offer commercial services, the final product refers to the numerical data of the age and the thermal evolution of the samples (numerical modeling).
In LA.TE. ANDES, we go further and comprehensively develop the interpretative analysis of the results, framing it in the geological knowledge and valutation of factors that intervene in quantifying the resources potential of the region.
The key element that allows this qualitative difference is the close collaboration and interaction with Geomap S.A., both in the sampling phase and in the analytical and interpretative phase. His experience and deep knowledge of the Sub-Andean System of North of Argentina and Bolivia through more than 25 years of activity are thus incorporated into our final product.
Heavy minerals concentration
Through physical methods of crushing and grinding of the rock sample provided, its subsequent sieving and the use of Franz magnetic separators in addition to dense liquids, to achieve the desired result.
Preparation of mirror polished samples
For different microscopic studies, among which are the petrography of opaque minerals, fluid inclusions and fission tracks in apatites and zircons.
Obtaining the Central Age and Closing Temperatures
Fission tracks dating in apatites and zircons, using Trakkey software.
With apatites or zircons, once a minimum measurement was obtained in 100 crystals, and the measurement of confined track lengths.
Neutron irradiation of minerals.
In minerals such as apatite and zircon and/or synthetic materials, glass, etc.
Numeric modelling of the fission tracks evolution
The data are modeled with HeFty and Pecube software, obtaining information about temperature-time path, in addition to temperature ranges, burial and exhumation ages or tectonic events. As a result, interpretation and final report are obtained.
Modeling of organic matter thermal evolution
Through the Petromod sofware (Petrotrack module) the degree of maturation reached by organic matter is obtained, which implies the range within the generation window in which a formation is.
Content of CI - F in apatites
Using Raman Spectrometry.
Composition of fluid inclusions
Determined with the help of Raman spectrometry.
