The
MOON
Rocks
To touch the Moon, you needn't to be an Astronaut.
The formation of our satellite, the Moon, has always been the subject of debates and theories, so fierce at times, that it was not until 1969 that humans came to it and brought samples of its surface, we did not begin to see the light at the end of the tunnel.
And so it was that after the arrival of the more than 380 kilos of rocks collected on the surface of the Moon by the crew of the Apollo missions, scientific interest in their research has grown, and this has allowed us to unravel interesting mysteries, including the of the existence of a group of strange meteorites whose origin was, until then, unknown. It was finally revealed that they were lunar meteorites.
Due to its proximity to our planet, the lack of lunar atmosphere and the size of the Moon, we suspect that the largest number of meteorites that arrived on our planet come from our satellite, but the fact that they are materials that are very similar to terrestrial ones and their high speed of integration into the ground, they make them rare to find, and this has positioned them as true gems for science and collectors.
Lunar Science
The lunar meteorites are, together with the Apollo and Lunik samples, the main source of scientific and geological information we have about the satellite, and through them we have revealed not only the origin and formation, but the evolution of the Moon and its importance for our planet.
Deep Lunar knowledge
Since then, the investigation of lunar meteorites has allowed us to discover textures, compositions, anomalies, and many chemical and structural details formed in their particular environment. Practically all types of meteorites have also been identified among the samples from space missions, and this point is interesting because we have a large amount of lunar materials in the form of meteorites that allow us to carry out in-depth investigations.
Analyzing and classifying lunar meteorites is an important milestone. Science is endowed with very valuable material for scientific research, and at the same time the value of rocks found in the desert is greatly increased. Are lunar meteorites worth analyzing and classifying? Yes, always.
Complex Rocks
When we look at the Moon one night during its full phase, we can clearly perceive two well differentiated regions, a bright and white part, which we call Highlands, and another dark area that we call Seas. The Lunar Highlands are pristine, their radiometric ages place them at the very origins of the Solar System, while the seas are younger lands formed from basaltic lava flows arising from the interior of the satellite.
Over the millions of years, the geology of the lunar surface has been profoundly altered by the collision of asteroids and micrometeorites, which have turned the bedrock into a thick layer of crushed materials we call Regolith.
Large impacts on this regolith produced the compaction of its materials and ejected them into outer space in the form of Brechas.
Lunar Breccias
Lunar Breccias are compact rocks, as their name suggests, brecciated, composed of broken anorthosite clasts in a feldspathic matrix, in which we can also find other components such as vitreous spherules, basaltic or gabbroic clasts, troctolytic, or even exterior asteroidal contaminants, such as metallic iron, sulphides or eucritic clasts.
They are rocks present great complexity in their study, precisely due to the multiplicity of components and their particular geological histories. But they are authentic history books that reveal the transformation the Moon has undergone throughout its geological history.
Mare Basalts
Lunar Basalts are rocks of volcanic origin, formed from lava flows and have revealed that their magmatic sources are different, thus producing basalts rich in titanium, and poor in titanium. This particularity also influences the size of the grain. Basalt or lunar grabro type meteorites are very rare materials, and really coveted by collectors.
Lunar basalts can be breccias or unbrecciated, and sometimes showing glass spherules.
The search for lunar meteorites in desert is a true adventure, especially since it is full of stones that may perfectly look like moon rocks, and they are not. In this task of identifying lunar meteorites, the finders always have the support of laboratories and professionals who will shed the necessary light to identify them and certify the authentic ones.
Preserving Lunar Rocks
Lunar meteorite recovery is extremely important to lunar science. They have become delicate jewels of vital relevance in collections around the world, and have allowed scientific research to advance in a surprising way. For this reason they are, perhaps, one of the main research assets in our laboratory.
If you think you have found a lunar meteorite, do not hesitate to contact us. The identification of these meteorites will allow to apply the necessary care to protect and preserve them in the best conditions, and prevent their loss and deterioration over time.

Sampling a sample
Different lithic clasts in lunar regolith
Lunar regolith is an amazing source book of science. Different types of lithic and minerals clasts allow to the science, know the history of the lunar surface. This soil is the important layer where the Moon and the Outer Space interact between them.
Analysis of lunar thin sections reveal the complex history of a lot of debris from the pristine bedrock.
The Moon under the microscope
A wide variety of lunar clasts were documented in meteorites.
The Moon is a star that has proven to be very heterogeneous, both in its original components and in those altered by continuous impacts. This has allowed researchers to document a wide variety of lithic and mineral clasts that offered valuable information about lunar geology.
Some Lunar Specimens in our Laboratory
We currently have numerous lunar specimens preserved in the laboratory repository. Specimens preserved for scientific research as hand rocks and thin sections, also small untouched fragments for analysis.
CAZADORES de METEORITOS
En busca de la Geología fortuita del Universo.
En Enero sale a la venta mi nuevo libro, con el que espero que todos disfruten, y mucho. Una interesante reflexión sobre los tipos de meteoritos, haciendo un recorrido por sucesos y momentos cruciales en la historia de la meteorítica. Chladny, Plinio, la extinción de los dinosaurios, los buscadores del Sahara, coches y personas colisionados por meteoritos, Chelyabinsk, Meteoritos en los juzgados, y buscadores en la cárcel. Meteoritos vistos por la Inteligencia artificial. Los más grandes, y los más valiosos... Creo que nadie debería dejar de leer este libro en el que analizaremos todas estas cuestiones, y mucho más... Quizás después también tú quieras convertirte en un CAZADOR DE METEORITOS.
