Brown, of Challis, Idaho, sent a specimen of a very fine cottony mineral of snow white color to the United States National Museum for identification. This mineral, which was thought to be asbestus, was said to be available in considerable quantity. Upon examination in the Museum laboratory this was found to be a fibrous zeolite, and optical examinations by Wherry and Larsen showed it to have properties similar to those of the rare mineral ptilolite. Chemical examination by Koch supported this conclusion, although the mineral was so mixed with small grains of quartz that it was not suitable for analysis. In 1921 a box of some 50 pounds of specimens of the zeolite and associated minerals from this locality was… Leer más

"The locality of Westfield, Massachusetts, has within the past 18 years produced datolite crystals in such abundance and of such unusual size and perfection of form that the specimens have become well known and are now widely distributed in mineralogical collections. While a resident at Springfield, Massachusetts, between February, 1918 and April, 1919, the present writer had opportunity at intervals to visit the quarries which yield the datolite. The modes of occurrence of the datolite and associated minerals were carefully observed with a view of describing the locality, and the crystallographic and other characters of the several minerals, with a discussion of their paragenesis and origin." .
