Introduction: Traditionally, the diogenite meteorites have been viewed as orthopyroxenite cumulates with small amounts of olivine [1]. Several olivine-rich, harzburgite diogenites have recently been recognized and may provide insight into the occurrence of olivine on Vesta and in the HED meteorite suite [2,3]. In both the harzburgite and orthopyroxenite diogenites, olivine has been interpreted ...

We review the radiometric ages of the 16 currently known Martian meteorites, classified as 11 shergottites (8 basaltic and 3 lherzolitic), 3 nakhlites (clinopyroxenites), Chassigny (a dunite), and the orthopyroxenite ALH84001. The basaltic shergottites represent surface lava flows, the others magmas that solidified at depth. Shock effects correlate with these compositional types, and, in each c...

Introduction: Twelve Martian meteorites that have been recovered so far are classified into five groups (basalt, lherzolite, clinopyroxenite, dunite, or-thopyroxenite) mainly from petrology and chemistry [e.g., 1]. Among them, the dunite and orthopyroxenite groups consist of only one meteorite, respectively (dunite: Chassigny, orthopyroxenite: ALH84001). The basalt group is the largest group an...

The lopolithic Pados-Tundra layered complex, the largest member of Serpentinite belt–Tulppio belt (SB–TB) megastructure in Fennoscandian Shield, is characterized by (1) highly magnesian compositions comagmatic dunite–harzburgite–orthopyroxenite, with primitive levels high-field-strength elements; (2) maximum values Mg# olivine (Ol, 93.3) and chromian spinel (Chr, 57.0) Dunite block (DB), which ...

A comprehensive study of a 340 m thick lenticular-sheet body ultramafic composition penetrated by structural well M-1 at depth about 2.2 km was accomplished. Its main volume is composed plagioharzburgite; fine-grained rocks norite and orthopyroxenite chilling zones are preserved on endocontacts. The the similar in to near underlying ore-bearing layered intrusion – Monchepluton. age 2510 ± 9 Ma ...
