Study of the structural properties of strontianite
SrCO3 under pressure," Universite/Laboratoire de Genie Civile, Algeria;
3 m bentonite, represented by several magmatic (magnetite, Ti-oxide, albite) and authigenic (pyrite, strontianite
, goyazite-florencite, kaolinite and illite) grains.
Also the Watzls had a few specimens, found in 2003, of another Austrian classic; strontianite
from the magnesite mine at Oberndorf-an-der-Laming, Styria.
Some chapters, such as the one on celestite and strontianite
, are only two pages long, listing their seven uses.
Ebenezer Emmons (1799-1863), a physician, chemist, agriculturalist, stratigrapher and paleontologist with the Geological Survey of New York, contributed the most specimens (46), including strontianite
(Emmons 1835), from the well-known localities in the Schoharie area of New York State (Fig.
Lines covered in the deal include salts, sulphur (except sublimed, precipitated and colloidal sulphur), natural graphite, quartz, silica and quartz sands, kaolin or other kaolinitic clays, bentonite, decolourising earths and Fuller's earth, fire-clay, andalusite, mullite, chamotte, microdol, natural calcium phosphates, natural barium sulphate, natural barium carbonate, gypsum, white asbestos, talc, natural arsenite, strontianite
(not stronitium oxide), natural cryolite and chiolite, fluorspar, vermiculite, perlite and chlorites (unexpanded), and others.

Other minerals which occur in significant quantity in Malawi and which, under more favourable economic circumstances, could perhaps be worked on a commercial scale, include apatite, bauxite, kyanite, monazite and strontianite
, and niobium minerals.
ankerite, siderite, witherite, strontianite
, may form if the respective metal cations are available.
A combination of well-characterized minerals and synthetic materials were used to calibrate for EPMA, including SMS scapolite (S and Cl), Corning W glass (6) (Co), SMS gahnite (Zn), SMS cassiterite (Sn), SMS strontianite
and Corning X glass (Sr).
