\997a,b), scapolite occurs in assemblages with anhydrite, amphibole, pyroxene,
garnet, plagioclase and pyrites, and is associated with baryte-hyalophane-
sulphide ores of submarine exhalative origin. The scapolite is a sulphate-rich
meionite ...

Gems: Their Sources, Descriptions and Identification
Despite low levels of barium being present in most K-feldspars the barium-rich
feldspars, hyalophane and celsian, are rather rare and gems even rarer. The
optical and physical properties vary considerably; generally increasing linearly
with ...

show close to 4% of BaO present, proving this material, at least in part, to be
hyalophane. Hyalophane, as a distinct feldspar mineral, was discovered and
identified in Pennsylvania by W. H. Tomlinson (Corundum in a dike at Glen
Riddle, Pa.; ...

The result approximates the composition of a sodium- rich hyalophane but is
deficient in silica. The optical data are thus supported by the analysis. An attempt
was made to purify some of the material, finely ground, in a heavy solution, but it

U.S. Geological Survey professional paper
The normal mineral composition of the average lava of the region will evidently
be very similar to that of the andesites of the second period of eruption. It is as
follows : « Orthoclase contains 0.35 per cent of hyalophane. Pyroxene eoasists of

Radiogenic Isotopes in Geologic Processes
The latter plateau value, younger than the Rb-Sr age, demonstrated partial reset

Volcanic feldspars are represented by sanidine and minor hyalophane (BaO >2
wt%). Na-feldspar and rare K-feldspar may have been derived either from the
Cenomanian-Turonian bedrock clastites or by aeolian transport. The majority of ...
