A simple fusion method for determination of plagioclase feldspar from thin section Cited by: 8.   The thin section shows a lot of feldspar with zonation and twinnings. Not sure if its a body fossil of a soft-bodied organism or a trace fossil. Fragments of unidentified plant fossils were also. Determination of thin section thickness The birefringence of anisotropic minerals can be determined in approximation by comparing the interference colours to those of the Michel-Levy colour chart, or it can be done precisely using the compensation method. For both methods the thickness of the mineral in thin section must be Size: 13MB. Rocks and Minerals in Thin Section, Second Edition: A Colour Atlas W.S. MacKenzie, A.E. Adams, K.H. Brodie This concise, clear and handy–sized volume, aimed at the undergraduate level, provides an introduction to the observation, description and identifi cation in thin section, using the polarizing microscope, of samples of the.

The barium feldspar celsian (Cn) is isostructural with sanidine with which it forms a continuous solid-solution series at high T. At high T there is extensive solid solution in the quaternary system BaAl 2 Si 2 O 8 (Cn)CaAl 2 Si 2 O 8 (An)NaAlSi 3 O 8 (Ab)KAlSi 3 O 8 (Or) but natural assemblages suggest several miscibility gaps at low T. Forms with different degrees of Sil order occur naturally. Sodium cobaltinitrite is inorganic compound with the formula Na 3 Co (NO 2) 6. The anion of this yellow-coloured salt consists of the coordination complex [Co (NO 2) 6] It was a reagent for the qualitative test for potassium and ammonium ions. 1 Synthesis and reactions. 2 Application for analysis of potassium.

IDENTIFICATION OF FELDSPARS IN CLASTIC ROCKS The total feldspar content of the fraction is measured by counting a stained sample. Early life & education.
