The photo to the left and the above text describing it are taken from a paper entitled "Zoned contact-skarns of the Broadford area, Skye: a study of boron-fluorine metasomatism in dolomites." C.E. Tilley; Mineralogical Magazine, 1951, Vol. XXIX. It appears that the acicular opaque mineral is ludwigite and magnetite, and most of the clear areas are fluoborite, both magnesium-iron borate minerals.
