AGUAS ZARCAS Hammer Stone Meteorite 1,071g I Carbonaceous Chondrite CM2 I Pre-rain with CRUST
On Offer: 1,071g Aguas Zarcas Hammer Stone - Carbonaceous Chondrite pre-rain meteorite, piece of the roof and tables that were also hit for display of this historical event from the April 23rd, 2019 fall in Costa Rica.
Description: Pre-rain 1,071 gram Aguas Zarcas carbonaceous chondrite hammer stone. This is the meteorite that ripped through a metal roof in Aguas Zarcas and started it all. The meteorite comes with the metal roof panel that was holed, as well as all other items the meteorite hit or damaged. A unique opportunity for an institution or private collection to acquire an exceptional piece of meteorite history with unique scientific significance.
The meteorite is classified as a CM2 carbonaceous chondrite. This CM2 carbonaceous chondrite is from Costa Rica's recent fall on April 23, 2019 and is arguably the most important meteorite fall since Murchison fell in Australia in Sept 1969.
Type: CM2 Carbonaceous Chondrite
CM2: The "C" designates carbonaceous and the "M" indicates Murchison-like. The numeral "2" after the CM indicated the level and type of: "equilibration 3 - 7" or "aqueous alteration 1 - 2". For this meteorite the designation of 2 indicates it has been altered by water after its formation. Pretty amazing!
What does "pre-rain" / "post-rain" mean? - This is a term being used for Aguas Zarcas meteorites that were recovered within the first 48 hours after the fall event, but prior to the start of local rains. These specimens are believed to be less contaminated with terrestrial water, which is significant because the CM2 is known to have considerable amounts of native H2O. Those specimens recovered after the rains started "post-rain" specimens, seem to have ubiquitous oxidation marks, while the "pre-rain" specimens seem to have little or no areas of oxidation.
The Recovery Expedition: Aguas Zarcas was probably the most exciting and successful meteorite recovery expedition I have ever been involved in. I was fortunate to personally recover approximately 633 grams of this CM2 meteorite, and was able to purchase or trade for another ~ 3 kilograms of the meteorite. My team and I were also fortunate enough to recover some of the "Marina" hammer stone fragments that went through the Marina community center's green tin roof. It was an adventure that lead us deep into the Costa Rican rain forest, through vast tracks of farmland cut from jungle, up mountain roads muddy and impassable even by 4x4 on the worst days. Dashes into a bull filled field, risky crossings of raging rivers. Pleasant walks and breathtaking views. Amazing animals and wildlife everywhere you turn. It introduced us to the beauty of the local people, their generosity and hospitality. We came to recover a fall, and fell in love with it all. Aguas Zarcas, is forever in our hearts.
What you get: 1,071 gram AGUAS ZARCAS Hammer Stone Carbonaceous Chondrite Meteorite Specimen as shown, piece of the roof that was hit and broken, and tables that were also broken by the impact of the stone. Signed Certificate of Authenticity.
