Diogenites are recognized as a major constituent of the howardite, eucrite and diogenite (HED) meteorite group. Recently, several papers (Mittlefehldt, 1994; Fowler et al., 1994, 1995) have identified trace- element systematics in diogenites that app

The lunar crust, down to a depth of ∼65 km, is composed of older (>4.5 Ga) ferroan anorthosites and younger (4.43-4.17 Ga) Mg-suite lithologies which include dunites, troctolites, and norites. The anorthosites are generally inferred to represent fl

Impact is a dominant process acting on the surfaces of planetary bodies and is the major process that modifies the physical and chemical nature of planetary materials on atmosphere-free bodies once volcanic activity has ceased. Elements with relative

The lunar Mg-suite, which includes dunites, troctolites, and norites, makes up to 20–30% of the Moon's crust down to a depth of ∼ 60 km. The remainder is largely anorthosite. This report focuses on norites (which consist mostly of orthopyroxene a

Eucrite, howardite, and diogenite members of the achondrite meteorites are considered by many to be genetically related. Therefore, each provides a piece of the puzzle for reconstructing magmatic processes on the eucrite parent body (EPB). The interp

The Lodran primitive achondrite is thought to represent some of the earliest events in the differentiation of chondritic asteroids. Most researchers who studied Lodran believe that it is a restite from which a melt, enriched in the incompatible trace

Diogenites appear to be cumulates formed from one or more igneous reservoirs in the interior of asteroid 4 Vesta. Magmatism in this parent body gave rise to a series of related lithologies designated howardites, eucrites, and diogenites or “HED.”

Recognition of prolactin-secreting microadenomas has led to renewed interest in normal variations in sellar contour that may mimic pathologic changes. A study of sphenoid bones obtained at autopsy from 100 patients who had histologically normal pitui
