Name:
In allusion to its chemical composition and crystal structure as the HYDROXYL-dominant, monoCLINic member of the group and its relationship to humite which was named after Sir Abraham Hume (1749-1838), English connoisseur and collector of gems, minerals and artwork.
Isostructural with:
Hydroxylclinohumite is a monoclinic member of the humite group. It forms a continuous series towards clinohumite. The name "clinohumite" has commonly been used as a default when the F/OH ratio has not been determined. Since hydroxylclinohumite was approved as a separate mineral (1998), it has become apparent that hydroxylclinohumite is much more common than indicated in the literature and locality entries in Mindat. It should also be noted that some of the published analyses (Luc Yen, Vietnam and Kukh-i-Lal,Tajikistan) are very close to the borderline between the two minerals, and both of these minerals are probably present at many localities.
Hydroxylclinohumite often contain some Ti and the varietal name titanoclinohumite (older literature uses the name "titanolivine" for this variety) is commonly used. Zambonini (1919) came to the conclusion that "titanolivine" from Ala Valley (Piedmont, Italy) is a titanian clinohumite very rich in OH and pratically F-free; therefore, he proposed, unsuccessfully, to substitute the name "titanolivine" with "titanhydroclinohumite" or "hydroclinohumite titanifère" (the species hydroxylclinohumite has been instituted in 1998 only). Humite group minerals found in metamorphosed serpentinites are often hydroxylclinohumite.
It is difficult to distinguish minerals in the humite group, as they largely occur in the same environments and localities. Their physical and optical appearances are also similar, as is the occurrence as rounded crystals or anhedral grains. A quantitative chemical analysis (electron microprobe) combined with structural analyses (XRD) seem to be required to identify individual humite-group species with absolute certainty. It is therefore quite possible that some of the locality entries and photos may be incorrectly identified as hydroxylclinohumite.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure
- the conoscopic view for a grain cut perpendicular to the acute bisectrix, using
this mineral's 2V. The two small white dots mark the melatopes - the points
where the two optic axes emerge - and are shown only when they fall within the
field of view. The coloured bands are isochromatics, and the dark bands are
isogyres.
Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
