Semarkona is an LL3.00 ordinary chondrite that fell near Semarkona, India, in 1940. Its minerals experienced exceptionally little thermal metamorphism on their parent asteroid, preserving chondrules, fine-grained material, and other evidence from the early solar system. Researchers use it to investi...
Bishunpur is an LL3.1 ordinary chondrite that fell in India in 1895. Its very low petrologic subtype indicates that it experienced relatively little thermal metamorphism on its parent asteroid, allowing primitive components such as chondrules and fine-grained matrix material to remain comparatively...
Chainpur is an LL3.4 ordinary chondrite meteorite that fell in India in 1907. Its low petrologic type indicates that it experienced relatively little thermal metamorphism on its parent body, allowing many chondrules and other early solar-system materials to remain distinct. Researchers study it as a...
Krymka is an LL3.1 ordinary chondrite meteorite associated with a 1946 fall in Ukraine. Its very low petrologic subtype identifies it as a highly unequilibrated specimen whose components underwent comparatively little thermal alteration after accumulation on its parent body. The preservation of dist...
Qingzhen is an EH3 enstatite chondrite meteorite that fell in Guizhou, China, in 1976. The EH designation places it among high-iron enstatite chondrites, while petrologic type 3 indicates comparatively limited thermal equilibration and the preservation of primitive textures. Its highly reduced miner...
Tieschitz is an unequilibrated ordinary chondrite that fell in 1878 near Těšice in Moravia, now part of the Czech Republic. It is commonly classified as H/L3.6, reflecting characteristics intermediate between the H and L chemical groups and a relatively low degree of thermal metamorphism. Its abunda...
Sharps is an H3.4 ordinary chondrite meteorite that fell in Virginia in 1921. Its classification places it among relatively unequilibrated H-group chondrites, which contain abundant metal and preserve chondrules and other early solar system textures more clearly than strongly heated ordinary chondri...
H4 ordinary chondrite found in the United States, classified among moderately equilibrated H-group chondrites and studied for thermal metamorphic history.
