Laboratory Description
Research Lines
- Formation of chondrules.
- Survival of organic material during the entry of micrometeoroids into the earth’s atmosphere.
- Formation of fusion crusts in meteorites.
- Identification of micrometeoroids.
Collaborations
- Dr. Karina Elizabeth Cervantes de la Cruz (School of Sciences, UNAM)
- Dr. Alfred U’ren (Institute of Nuclear Sciences, UNAM)
- Dr. Héctor Cruz Ramírez (Institute of Nuclear Sciences, UNAM)
- Dr. Alejandro Heredia Barbero (Institute of Nuclear Sciences, UNAM)
- Dra. Patricia Hernández Reséndiz (Research stay - Institute of Nuclear Sciences, UNAM)
Infrastructure
- Stereo microscope for transmitted and reflected light (Motic SMZ168): used for identifying morphological and textual aspects in hand specimens.
- Petrographic polarizing microscope with transmitted light (Motic BA310-Pol): used for identifying rocks and minerals in thin sections from their optical properties.
- Citlalmitl: an experimental device designed and created for simulating quick high-temperature phenomena to which meteorite components or micrometeorite precursors might have been subjected. This device is located at the Quantum Optics Laboratory (Institute of Nuclear Sciences, UNAM).
