and yellow chondrodite from Tanzania.
Clinohumite is an uncommon member of the humite group, a magnesium silicate with the chemical formula (Mg,Fe)9(SiO4)4(F,OH)2, which is essentially a hydrated olivine.

Jentsch Minerals and Rough Stones (email@example.com) was just beginning to develop a contact-metamorphic deposit near Morogoro, Tanzania where crystals of clinohumite, graphite and other unusual species accompany good octahedral crystals of spinel.
The Afghan clinohumite crystals are lenticular and face-rich, reach 2.5 cm, are gorgeously colored and in a few cases are even gemmy; they rest in matrix of flaky greenish muscovite and/or talc, making for very attractive, mostly thumbnail-size specimens which were in evidence all over Tucson this year.
Next, there is an intriguing new discovery of spinel and clinohumite
crystals embedded in a "dirty" white marble from a contact-metamorphic deposit near Morogoro, Tanzania, these specimens having been brought to the new Executive Inn show by Jochen Hintze of M.

In addition to the W and Mo ore minerals scheelite (occurring in white, gray, black, and yellow crystals) and molybdenite, the skarns also host a number of interesting accessory minerals including: allanite, anhydrite, chalcocite, chalcopyrite, clinohumite
, covellite, ilmenite, bismuthmite, marcasite, pyrite, pyrrhotite and scapolite.
All four of the classic members of the humite group - humite, clinohumite
, chondrodite and norbergite - are found at Monte Somma/Vesuvius.
