Efremovka is a reduced CV3 carbonaceous chondrite found in Kazakhstan in 1962. It contains well-preserved chondrules and calcium-aluminum-rich inclusions, among the earliest solids known to have formed in the Solar System, as well as presolar grains inherited from material predating it. These compon...

Indarch is an EH4 enstatite chondrite that fell near Shusha in present-day Azerbaijan in 1891. Its highly reduced mineral assemblage includes abundant enstatite, iron-nickel metal, and sulfide minerals, with little iron bound into silicates. Researchers study Indarch to investigate the formation of...

Leoville is a CV3 carbonaceous chondrite found in Kansas and assigned to the reduced subgroup of CV meteorites. It contains chondrules, calcium-aluminum-rich inclusions, metal, and fine-grained matrix that retain evidence of early Solar System processes. Its comparatively limited thermal and aqueous...

EL6 enstatite chondrite that fell in Finland in 1901, a key reference sample for the low-iron (EL) enstatite chondrite group in geochemical classifications.

EL6 enstatite chondrite found in Pakistan in 1873, one of the most-studied low-iron enstatite chondrites and an important reference for the EL chondrite group.

EH5 enstatite chondrite that fell in Florida, USA in 1937, a well-characterized member of the high-iron enstatite chondrite group used in comparative studies.

Aubrite (enstatite achondrite) found in the Northern Cape, South Africa in 1868, one of the few aubrites recovered from the African continent.

Chondrite that fell in Bihar, India, in 1942, studied for its primitive mineral assemblage as a record of early solar system chemistry.

Minichess is a category of chess variants played on smaller boards, most commonly 5x5 or 6x6 grids, designed to create faster games with immediate tactical engagements from the start.
