Some chondritic meteorites often contain spinel in the calcium-aluminum rich inclusions (CAI’s) so spinel is an extra-terrestrial mineral as well! The ROM is fortunate to have a fabulous array of spinels on display and the most significant being this lovely lavender pear shaped 61.45 carats spinel from Myanmar (formerly Burma).

Carbonaceous chondrites represent the most primitive rock samples of our solar system. This rare (less than 5% of all meteorite falls) class of meteorites are a time capsule from the earliest days in the formation of our solar system. They are divided into the following compositional groups that, other than CH (High Metal) and C-UNG (Ungrouped), are named after the first or most prominent

16/4/2014· Calcium-Aluminum Inclusions (CAIs) A very different inclusion is prominent in CV3 chondrites. They are non-igneous (interpreted as evaporative residues or gas-solid condensates by uniformitarians) or igneous (interpreted as possibly melted condensates by uniformitarians) objects rich in Ca, Al, and Ti giving their name Ca-Al inclusions, or CAIs (Krot et al. 2009; MacPherson 2005).

CAIs are found in a majority of chondritic meteorites, from undifferentiated parent bodies, and range in size from cm- to micron-scale. As a whole, chondrites have very similar and rather uniform chemical compositions (isotopic characteristics vary to some degree between types).

13/8/2020· Last year, an unusual meteorite crashed in a Costa Rican rainforest. Rich in the building blocks of life, it has captivated collectors and researchers. As the fiery emissary streaked across the skies of Costa Rica, an unearthly mix of orange and green, Marcia Campos Muñoz was in her pajamas, watching TV on the couch. It was 23 April 2019, a bit past 9 p.m., when she heard a foreboding rule

A third class of components consists of refractory and mafic inclusions (e.g., calcium-aluminum–rich inclusions; Grossman, 1975) that are more abundant in carbonaceous than in ordinary chondrites. These unique objects emerged from high-temperature melting-evaporation-condensation processes in the earliest episodes of the solar nebula ( Grossman et al., 2002 ).
