Soil properties of the six selected soils for the K uptake trial Dominant clay minerals given only; other clay minerals measured were albite, orthoclase, sanidine

Analysis proved the felspar to be sanidine
, a disordered potash felspar.
An exploration well is planned for mid 2007 on the Sanidine
prospect in the Kiarsseny license, while two wells will be drilled in the Nziembou license as part of the wider Niungo program.
composition has been studied in twelve drill-cores with an aim to identify the ash beds in the Telychian of Estonia.
Despite the inclusion of statements such as 'all contain sanidine
in the groundmass as well as significant amounts of plagioclase .
Essential minerals are phenocrysts and glomerocrysts of anorthoclase, sanidine
up to 1,5 cm and anorthoclase-mantled plagioclase; accessory minerals are red biotite, and hastingsite while trace minerals are augite, zircon, sphene and magnetite.
1986, Proterozoic sanidine
and microcline in pegmatite, Wausau complex, Wisconsin, Canadian Mineralogist, v.
The tuff is covered with 3 to 4 feet of claylike soil and alluvium, composed mainly of quartz, feldspar, sanidine
crystals, rhyolite, and latite.
Analysis by X-ray diffraction showed that, apart from the quartz, which is dominant, about 5% of albite is present with a lesser amount of sanidine
, but no iron oxide.
In the most recent effort, the researchers dated sanidine
, an ideal mineral because of its tight crystalline lattice.
