Laboratory

Thin sectioning, petrography, geochemistry and magnetic susceptibility for the characterization of meteorites and related materials. We also provide curation, identification, restoration, and the management of official classification in the Meteoritical Bulletin when applicable.

Submit samples

What is done with the sample?

All positive samples (which is why complete rocks are not allowed, only samples of them) will be deposited in the repository as a means of determining the documentation that is delivered to the client and that is extensible to the complete part that they have in their possession. These samples, devoid of commercial value, are the testimony of the legal validity of the documentation that will be issued after studying them. The remains of negative samples are discarded or destined for research and educational purposes.

How long does the study of a sample take?

This question is a serious one, and we are asked it very often. The time it takes to complete the analysis of one or more samples will depend on several factors. Generally, it is usually finished within a period of between 20-60 days after receiving the sample. But if there is backlog of work in the lab, it will be queued until it can be processed. Times are variable, and not conclusive. The times are marked by laboratory work, and external pressures will not exert any benefit. Please, be patient. Don't be continually emailing to find out about your results. When they are ready they will be notified. Check your spam or spam folder.

In the case of geochemical analysis, or classification processes, they can often be concluded between 90-180 days, however there are classifications that take many months, even years. It is important to be patient, since any news in the progress of the processes will be communicated to the client without delay at the time they occur. We appreciate your maximum patience. The laboratory has its times.

Services

Thin Sectioning

High-quality petrographic thin sections for rocks, fossils, and meteorites. Discounts for batches.

Analytical & Curation

Evaluation of suspect meteorites under meteoritics standards, recovery treatments, conservation protocols and handling procedures.

Documentation

Technical reports and scientific imaging for private and institutional collections.

Official Classification

Complete management of the Meteoritical Bulletin submission for new finds when the requirements are met.

Types of analysis and scope

Choose the right technique for your goal, and request the PDF protocol with the full information (procedures, prices, shipping address, payment methods)

Petrography (thin section)

Polarized-light microscopy to identify minerals, textures, shock features and weathering. It does not provide bulk chemistry. Essential for proper meteoritic classification.

XRF (X-ray fluorescence)

Major/trace elemental composition of the bulk sample (oxides/elements). It complements petrography with quantitative chemistry.

Magnetic susceptibility

Induced magnetic response; widely used for classification and for discriminating terrestrial materials. Recommended with other analyses.

Documents, links & protocols

Reaching official meteorite listings, institute correspondence, and practical information before you ship samples or request a study.

Important: Request the ANALYSIS AUTHORIZATION FORM and acceptance of conditions before sending samples to the laboratory. Sample analysis will not be performed without this form.

Laboratory in practice

From classification to curation

Examples of real workflows: new submissions, petrography, controlled storage, and recent fall material prepared under the same standards applied to client studies.

Meteorite classification documentation at the laboratory bench — Classification workflow: documenting incoming meteoritic material before analysis and reporting.

Petrography and sample preparation workspace — Petrography workspace for thin sections and polarized-light microscopy.

Lunar and astromaterials in curated storage — Curated storage for sensitive astromaterials, including lunar-related samples.

Sample handling and conservation — Handling and conservation steps prior to analysis or repository deposit.

Asteroid 2024 BX1 fall material in the laboratory — Recent fall (2024 BX1 Asteroid): material prepared for scientific study under laboratory protocols.
